The FDA just did something remarkable with sunscreens

The FDA just did something remarkable with sunscreens

© 2019 Arthur W. Perry, MD

Last week, the FDA said that the only two sunscreen ingredients that are safe and effective are zinc oxide and titanium dioxide.  That’s absolutely remarkable.  But not to me.  I’ve been saying that for years and even went on the Dr. Oz television showstating this.  And every sunscreen I’ve ever designed, including my Dr. Perry’s DayThyme SPF20 and my upcoming Dr. Perry’s SunThyme SPF30, include only the safest zinc oxide. 

The FDA’s new rule proposes to ban PABA and trolamine salicylate, two of the most dangerous sunscreen ingredients.  That leaves 12 so-called “chemical” sunscreens on the market, although right now the FDA does not consider them to be generally recognized as safe and effective.  So, if the FDA is not convinced they’re safe, why would you?

The FDA also will require all SPF 15 or higher sunscreens to be effective against UVB (which the SPF measures) and UVA (which has nothing to do with the measured SPF).  That’s good for consumers, because the average person really should not need a chemistry degree in order to be able to use safe sunscreen.

You may wonder why companies want to make sunscreens with unsafe ingredients.  Two reasons – they are cheap and the chemicals are easy to work with.  And while I don’t generally like government intervention in our lives, this is where it is necessary.  If you are happy with the short story, stop reading here…. But if you want to know why I, as a plastic surgeon and biologist consider sunscreens with chemical ingredients unsafe, keep reading…(In the spirit of scientific accuracy, I've even included some scientific references for you...)

The FDA is worried about chemical sunscreens with an unproven safety record. The scariest thing is their potential to cause cancer.  Benzophenones may cause ovarian and breast cancer, leukemia and other cancers. [1][2][3][4] [5][6].  PABA and Padimate-O are also suspected carcinogens [7][8][9][10].   Ensulizole damages DNA and might also be a carcinogen.[11]  Benzophenone and oxtinoxate are considered very risky substances.[12]   

Most sunscreens are endocrine disruptors

Nine of the 15 chemical sunscreens are considered endocrine disruptors- chemicals that interfere with the normal function of hormones[13].  Endocrine disruptors that interfere with estrogen, progesterone, testosterone, thyroid, and steroids contribute to cancer, diabetes, obesity, and infertility. Endocrine-disrupting chemicals have likely been the cause of increases in breast, prostate, and testicular cancer, diabetes, obesity, and decreased fertility over the last 50 years.  These chemicals are not proven to cause cancer but there is a higher risk of hormone related cancer in industrialized countries.  People who come from countries with lower cancer rates have a higher rate when they move to the United States.

In Great Britain, from 1978 to 2007, cancer increased by 32% in women. Breast cancer increased 57% in that time period.  In the US, childhood cancers increased almost 1% per year from 1975 to 2002. Many scientists believe this increase in cancer is due to bathing our bodies in toxic endocrine disruptors.

The 2009 Endocrine Society Scientific statement entails considerable evidence indicating that endocrine disruptors contribute to the risk of breast cancer, prostate cancer and testicular cancer[14].  These cancers may well be due to endocrine disruptors, particular estrogen like substances.  

Endocrine disruptors are worse for developing children, hurting development of their brains and reproductive organs.  That’s why pregnant women, breast feeding women, and growing children should avoid them.  Endocrine disruptors interfere with intrauterine growth in boys and girls and hypospadias and cryptorchidism in boys, small testicles.  In girls, they cause premature puberty, polycystic ovary syndrome, and abnormal periods.  In adults, low sperm counts, testicular cancer, prostate growth and in girls, vaginal cancer, breast cancer, ovulation disorders, uterine fibroids, and difficult breastfeeding.  

Exposure to estrogens throughout a woman’s life, including the period of intrauterine development, is a risk factor for the development of breast cancer.  Benzophenones specifically have estrogen effects. [15][16]  The increased incidence of breast cancer noted during the last 50 years may be because of women’s exposure to estrogen-mimicking chemicals that have been released into the environment.

Octylmethoxycinnamateshas hormonal effects and interferes with fat and thyroid metabolism. [17][18]  This very common sunscreen causes many different types of hormonal problems in pregnant animals.[19]   Octyl methoxycinnamate and avobenzoneare actually toxic to cells [20]and many sunscreens cause allergic reactions when exposed to the sun.[21]  Octyl methoxycinnamate, oxybenzone, homosalate, octyl salicylate, padimate-o, andsulisobenzoneincrease penetration of toxic herbicidesthrough skin.[22]   And most sunscreens increase the penetration of pesticides.[23] A large number of animal and laboratory studies have shown numerous adverse effects including developmental and reproductive effects of UV-filters present in sunscreens and cosmetics. 

So here’s the bottom line.  Because chemical sunscreens get into the body, blood, and tissues and are not considered absolutely safe, I believe thatchemical sunscreens shouldn’t be used in children or pregnant or breastfeeding women.[24]Read labels and avoid sunscreens that list any active ingredients other than zinc oxide or titanium dioxide.   And remember, you are safe with my DayThyme SPF20 skin protector...

Fraud in Sunscreens

By Arthur W. Perry MD July 6, 2018 No comments
Did you know that so much of the sunscreen industry operates dishonestly? It's because of the prolific use of what are called SPF boosters. Never heard of them? Most people haven't. So here's a primer on why mineral sunscreens are the best sunscreen ingredients but you might not be getting pure minerals even if the label says so... Zinc oxide is the best sunscreen agent because it does not get absorbed into the body and it does not get “used up” by the sun. But there is a pretty strict relationship between the SPF achieved per % of zinc oxide in the cream: Every 1% increases the SPF by between 1.5 - 2.5, depending on the exact preparation. The elegant forms of zinc oxide (micronized = small particles, nano = very small particles) are much more expensive than the chemical sunscreens and most of them are patented. Elegant mineral sunscreens (ones that disappear on the skin and do not feel tacky) are 10 times costlier than chemical sunscreen ingredients. Most companies that advertise “mineral sunscreens” include a mix of cheaper chemical sunscreen agents. But, chemical sunscreens are almost all endocrine disruptors and, by definition, must be absorbed into the body to function (that is why they have to be applied 20 minutes before going into the sun). They hang around the body for 48 hours after application. No other drug, other than antacids, is consumed in such high amounts. And chemical sunscreens are topical drugs that are not processed by the liver before traveling to every organ in the body. The other game played by sunscreen companies is the use of “booster” chemicals. Boosters indeed block or absorb ultraviolet light, but they are not approved by the FDA for this purpose and therefore can not be listed on the label as a sunscreen agent. The FDA has a very short list of ingredients that can not be included in skincare preparations, and boosters are not on that list. That allows their use as simply “inactive ingredients”. Companies use this to their advantage, because they can achieve higher SPF values with just “mineral” sunscreens, and can legally claim to be “100% mineral” even though their SPF is largely achieved through the use of chemical boosters. Some commonly available mineral sunscreens advertise their SPF of 60 but list less than 10% mineral sunscreens on the label. This is physically impossible without the use of boosters, because the level of minerals in the sunscreens can only generate an SPF in the low 20s. Dr. Perry's DayThyme SPF 20 sunscreen and our soon to be released SPF 30 SunThymeTM suncreen will be honest as to the ingredients, effective, and aesthetically elegant.

It's the results that count

By Arthur W. Perry, MD August 12, 2017 No comments
So many skin care products make absolutely ridiculous claims. They claim that their products can rejuvenate your skin in just hours. Or they claim to cure certain disease conditions of the skin. When I look at the ingredients, I know that this is just plain fraud. But how do you know? It's so tough, and the FDA tolerates these lies... Why? I suppose they have their plates full with regulating medical devices and the entire food and drug supply of the United States. So when it comes to ridiculous claims for plant stem cells (don't work) and hexapeptides (can't work), I guess they just figure that no one is being injured and so they don't waste their resources pursuing them. My patients and my customers know that I tell it like it is. And I create products that are honest. With real ingredients that are scientifically proven to work. On this website, I'll be posting photographs of women who have used my products and I'll show you their real results. Here's the first woman. She's 64 years old and has used my Basic Regimen (NightThyme, DayThyme, and CleanThyme) for 6 months. Most of the women in my study had similar results. Her photo on the top is before she started the program and the bottom photo is after 6 months.

Don't Shake the NightThyme!

By Arthur W. Perry, MD June 3, 2017 No comments
Some people want to shake their products. I'm not sure why, but I'm going to ask you NOT to shake your bottle of NightThyme. First of all, it's simply not necessary. NightThyme has been perfectly formulated as a beautiful serum. There's nothing floating around in there that you have to mix up. There's nothing that will settle down to the bottom of the bottle... But here's why I don't want you to shake the bottle (sounds a little like the old "don't squeeze the Charmin" commercial....). I received my patent on the unique way I preserve the Vitamin C in NightThyme. I bottle NightThyme under a little pressure, And as the Vitamin C in the NightThyme ages (oxidizes), it generates a little carbon dioxide. So that little bottle of NightThyme is sort of like a can of soda. And you know what happens if you shake a can of soda....watch out as it spews across the kitchen. The same thing will happen to NightThyme. So here's how I open my NightThyme. First, I refrigerate it to cool it down. Then I certainly don't shake it. Then I unscrew the cap slowly to release a little gas. You should hear a little "shvip" as it unscrews. And that's it. Keep it from getting too warm during the month that you use it. Room temperature is just fine, but don't let it sit in the sunroom. If you're stocking up, keep the extra bottles in the refrigerator. As for color - NightThyme starts out with a tiny tinge of beige. After about 6 months, there is a vague yellow color. After about a year, the color should be yellow. After 2 years, it will be darker yellow. After about 3 years, it will be light brown. It is still usable and will still have enough vitamin C with this color. When the product turns dark brown, it's thyme to toss it out.

The truth about "Organic" Skincare

By Arthur W. Perry, MD October 20, 2016 1 comments

“Organic” may be the most bastardized word in the English language.

The strict definition of “organic” chemicals are chemicals that are carbon based. Somewhere along the line, the term became associated with edible products that did not contain toxins such as pesticides, herbicides, or antibiotics. While the definition was not particularly good, the concept was a welcome one. And over the last two decades the “organic food” industry has been steadily growing.

In the last few years, the "organic" concept has become even more bastardized, with the introduction of “organic skincare”. Real chemists cringe when products containing substances like inorganic zinc oxide, titanium dioxide, talc, and iron oxide are described as “organic”.   We are entering a whole new world of obfuscation…. The FDA does not even have a legal definition for “organic” and so if a company calls their products “organic”, they must follow the US Dept. of Agriculture definition. This is particularly bizarre since inorganic minerals are not agricultural products.

But let’s go a step further and consider why a skincare product should even consider being “organic”. The concept comes from a desire for healthy, wholesome products, made with healthy ingredients. This is a reasonable goal, but consider a skincare product made from organically grown poison ivy. Legally it could be labeled “organic”, but you don’t need to be a physician to know that this is not something you would want on your body. It turns out that essential oils, which make up so many wonderful fragrances, may be organic but also may cause allergic reactions called “contact dermatitis”. In fact, 14% of the population are allergic to one essential oil or another. Synthetic fragrances, certainly not called “organic” but indeed may be created with organic chemicals (in the strictest sense of the word), are often less likely to cause allergies than the “natural” ones.

And that brings us to the definition and benefits of “natural” substances in skincare. Plutonium and cadmium are natural, but you sure would not want those chemicals near your body. On the other hand, phenoxyethanol is a synthetic preservative that is particularly nontoxic and helps keeps your products safe and fresh. But organic or natural? No. So we must all be skeptical of the cosmetics and skin care that describe themselves as “organic” or “natural”.

The truth is that a well formulated product that is carefully evaluated for toxicity and efficacy is what should be created... For my products, I try and keep as short an ingredient list as possible because I know that each and every ingredient, whether “natural”, “synthetic”, or “organic” has the potential to cause toxicity or allergy. I choose my ingredients for for their scientifically proven efficacy and I scour the toxicology database to eliminate anything that can potentially cause problems. That is not as easy as it may seem, because safe and effective ingredients, such as vitamin C, can cause a terrible corneal injury if splashed in the eye. And because of that concept, simple table salt or vitamins are often considered “mildly toxic”.

Skincare is not as simple as it seems, and that is the precise reason I, as a plastic surgeon and biologist, have enjoyed creating safe and effective products for you.

It's sunscreen season

By Arthur Perry MD July 18, 2016 No comments

It's the middle of summer. The time when the sun is at its most intense. And that means you need to protect your skin - no matter what color it is. Sunshine contains visible light and invislble ultraviolet light (UV). You know that visible light contains all of the colors of the rainbow, but you may not know that UV light also contains a rainbow of colors. But you can't see the colors of UV light (did you know that some animals can?). The two main "colors" of UV light are called "A" and "B" (those scientists know how to name them, don't they?). The SPF designation deals with UVB. If your sunscreen covers UVA, it is called "broad spectrum". Sounds simple...but it isn't. In fact, there are many "colors" within UVA (85 to be exact), and to earn the "broad spectrum" designation by the FDA, a product only has to block exactly 1 of the 85 colors of UVA. Most broad spectrum sunscreens only block a few of the UVA colors. And that's the problem. So what's the solution? Zinc oxide - it blocks ALL of the UVA and UVB colors. It's a complete sunscreen. And now you know one of the reasons I use zinc oxide in my DayThyme product. (For the other reasons, check out my blog on the Dr. Oz website http://www.doctoroz.com/article/your-sunscreen-might-be-poisoning-you)

How do you determine whether a product really works?

By Arthur Perry MD November 26, 2015 No comments
There are tens of thousands of skin care products in the USA. So many make absolutely ridiculous claims and so many contain ingredients that can't possibly work. But how can you, the consumer, determine whether a product or ingredient is useful...or useless. It's actually nearly impossible, unless you have degrees in both chemistry and medicine. I've spent years looking at ingredients and I do believe that some work...they do what they say they do. But the vast majority of products don't work. They either contain ingredients that are too big to penetrate the skin, or they don't have enough of an active ingredient, or they have ingredients that are destroyed by sunlight....the list goes on. I spend hours reading labels of products. Sometimes I snicker and then I wonder if the clerk thinks there's something wrong with me. When I design my products, I only use ingredients with proven effectiveness. I use enough of the ingredient to make a difference, and I use the types that are biologically active. That's why my slogan is..."with my products, you don't have to read the labels...I do it for you." Have a great Thanksgiving!

New NightThyme is Ready!

By Arthur Perry MD July 8, 2015 No comments

Greetings from Dr. Arthur Perry.  

I've got great news to share with all of you.  Beginning at midnight tonight, we'll be selling the new NightThyme. Here's the good news:  the actual product hasn't changed a bit.  Here's the better news - the pump bottle that was so, so finicky, has been replaced with a glass bottle with a dropper.  I guarantee you won't have issues with this bottle.  

If you've used NightThyme, you know what an incredible product it is.  It combines the real form of Vitamin C, high amounts of Vitamin A, 2 fruit acids in proper concentrations, 5 antioxidants including milk thistle, and 4 skin brighteners.  It's in a serum form because serums leave less useless residue on the skin than creams.  You know that your skin feels smoother the next morning after using NightThyme and that after a month or two, brown spots begin to fade and after several months, you notice less wrinkles.  But...that old pump was driving you crazy.  In the hot weather it could leak or stop working...despite the fact that it was the best and most expensive pump in the world (produced for me in France by Lablabo).  So, I set out to find a better pump.  None would work, because my product contains 20% acid and has a very low pH.  Ultimately, the solution was to package NightThyme in glass with a special type of cap.  I replace the air in the bottle with Nitrogen to preserve the product for as long as possible and refrigerate it from the moment of creation.  The glass is amber, to block light.

When you receive your new NightThyme, don't remove the cap until you are ready to use it for the first time.  Then replace the cap with the glass dropper cap.  I've tested the dropper cap and I know that the product does just fine, without refrigeration, with the dropper in place, for at least 5 months.  If you purchase extra bottles, you'll prolong their life by refrigerating them. 

I am confident that the new bottle will solve the problem of occasional leaks and pump issues.  Of course, glass bottles can break if dropped, so you'll notice that the new carton is a beautiful rigid box that can be dropped from 4 feet without the bottle breaking.  All of these changes cost quite a bit of money and the product cost is almost twice the original cost, but I have decided not to raise the retail price of NightThyme.  My goal is to provide the highest quality products at fair prices.  

I am so excited to offer this new NightThyme to you and welcome your feedback.  If you like my products, please tell your friends.  This is a "grass roots" company that I am trying to grow.

CleanThyme awarded a patent!

By Arthur W. Perry, MD, FACS February 22, 2015 No comments

I recently received a patent for my CleanThyme soap. "So what" you may say. Let me tell you why this is important.

It is pretty difficult to patent a product, no less a soap. The US patent office only grants patents for unique products - you've got to prove to them that your product is different from everything else on the market. I knew right from the start that CleanThyme was the most unique product that I've created. It is the only soap on the market that has the correct pH - it's acidic like the skin should be - and has no toxic sulfates, no preservatives, no petrolatum, and no dyes. The lather comes from the plant that makes root beer frothy. The bar is held together with edible beeswax. Even the fragrances are naturally occurring aromatherapy agents. They're proven to improve mood and decrease blood pressure. But since lemon oil sets you up for sunburn, I removed the part of lemon oil that does that.

It's one thing to make a scientifically perfect product. It's another thing to make a product that the public likes to use.  With CleanThyme, I hit a home run - it's a perfect product that cleans your skin without stripping it of your important natural oils.  It "performs" well with just the right balance of "slip" created with glycerin and oatmeal and..you'll love the tons of lather.  On top of that, it smells good enough to eat.

Traditional soap is one of the most toxic skin care products. It messes up the pH balance of your skin and allows bacteria to proliferate. The SLS in most soap destroys the barrier function of the skin, allowing toxins to penetrate and creating irritation and a syndrome of rough, oily, slightly red and swollen skin. Many of you have that and have always thought that that's how your skin always is. I addressed each and every problem with traditional soap and created CleanThyme.  

Now, you might be wondering why I made a bar soap, instead of a liquid soap, which looks so much fancier.  The simple fact is that bar soaps do not require preservatives.  And 14% of you are allergic to preservatives.  

Try my soap and many of you will see a difference in the appearance of your skin within a few days. (You've also got to start using an SLS free shampoo).

Now you can understand why the US Patent Office has decided that my CleanThyme is unique enough to warrant a patent. The only problem with CleanThyme? You'll never be able to use your old soap again.

Preservatives in skin care

By Arthur W. Perry, MD, FACS June 24, 2014 No comments
Preservatives are one of those things we don't want, but we can't live without. That's because we are surrounded by germs. They're everywhere - on our skin, on the table, on the floor, on your pet, in the garden. Bacteria, viruses, and fungi live (usually) in harmony with us. And they serve a useful purpose in the environment, helping organic matter decay. Anytime there is water, there will be bacteria. Just look at that piece of cheese way back in your refrigerator to see bacteria in action. The warmer and wetter it is, the more bacteria. That's why food grows bacteria. Refrigeration stalls the growth of bacteria and a so do preservatives. If you want something with water to stay fresh for more than a few days, it must have preservatives. That's why all cosmetics contain preservatives. The trick is to choose the safest ones. My CleanThyme does not contain preservatives because it's a solid. And the thyme and lemon naturally kill germs. My other products do require preservatives, but I purposely stay away from parabens and triclosan, notorious for their "endocrine disruption". In fact Minnesota just banned triclosan. I wish I did not have to use any preservatives at all, but then the products would not be able to sold commercially. So, I use the safest of all preservatives.
