What’s chemical sunscreen?
Chemical sunscreen is formulated to dam UV rays utilizing non-mineral UV filters. The time period ‘UV filter’ means a substance able to absorbing or reflecting UV rays to stop them from penetrating pores and skin.
The components listed within the “lively ingredient” portion of a sunscreen consists of all of the UV filters in a product.
All components aside from ‘zinc oxide’ or ‘titanium dioxide’ are chemical UV filters. – Dermatologist Dr. Cynthia Bailey
When a sunscreen has solely chemical UV filters it’s totally a chemical sunscreen.

You discover the lively UV filters listed on the again label of each sunscreen.
The FDA requires sunscreens to have again labels which can be titled ‘Drug Info’.
Energetic Components: The primary part on a sunscreen Drug Info again label lists the “Energetic Components”, that are the UV filters.
Inactive Components: All the different components, together with the bottom (cream/lotion/gel/liquid and so forth.) and different components equivalent to nutritional vitamins and antioxidants, are referred to as “Inactive Components”. They’re listed on the backside of that label. They aren’t thought-about ‘lively’ on the subject of sunscreen.
I’ve advisable mineral sunscreens over chemical sunscreens for over 20 years.
I advisable zinc oxide sunscreens to my sufferers beginning in 1999 when a nice type of invisible zinc oxide turned out there. I began this weblog in September of 2009, writing 2 posts per week for many of that point. I created my web site about 9 months earlier than that. In these 12 years, I’ve internationally shared my opinion that sunscreen with a minimal of 5% zinc oxide provides one of the best, most steady and trusted safety based mostly on doing a whole lot of 1000’s of pores and skin exams on Californians over my profession.
My sufferers introduced me the outcomes of their sunscreen utilization in actual life. The medical literature and business lagged behind, however my sufferers and I noticed what labored and it was 5% or extra zinc oxide. – Dermatologist-Insurgent and Pores and skin Wellness Professional Dr. Cynthia Bailey
The FDA and medical consultants are coming to the identical conclusion, although for various causes. My suggestions haven’t modified – and as we speak, we’ve got even higher zinc oxide sunscreen expertise than we did again in 1999.

Chemical sunscreen is extra fragile and fewer steady than mineral sunscreen
You will need to perceive that chemical sunscreen molecules are fragile, each when in your pores and skin blocking UV rays and when sitting in a bottle or tube ready so that you can use them.
The soundness situation with chemical sunscreens makes them much less reliable in my expertise and I’ve seen them fail to guard my sufferers even when used based on directions for correct software and reapplication. – Dermatologist Dr. Bailey
How does chemical sunscreen work?
Chemical sunscreen UV filters work by absorbing UV rays with a chemical response.
- Every time a UV ray causes this response, the molecule of chemical sunscreen is destroyed. It is likely one of the causes that you have to reapply sunscreen throughout extended solar publicity, mainly, you run out of chemical sunscreen molecules in your pores and skin as they block the solar’s UV rays.
- This chemical response additionally generates a little bit warmth which can make pores and skin really feel a little bit hotter than with mineral sunscreens.
Chemical sunscreen additionally wants time to bind together with your pores and skin earlier than it begins working. That is one purpose why we advocate making use of sunscreen half-hour earlier than solar publicity. This time enable the product to soak up into the highest layer of your pores and skin the place it is going to work.
What separates chemical sunscreen from bodily sunscreen?
Bodily sunscreen, additionally referred to as mineral sunscreen, blocks UV rays utilizing the bodily mineral particles of zinc oxide and titanium dioxide. These particles sit on the highest of your pores and skin and block the solar’s UV rays by each reflecting and scattering rays. Additionally they work to some extent by absorbing the rays.
It has lengthy been thought that the majority of their safety comes from bouncing the rays off of pores and skin. Just lately, a laboratory examine suggests that there could also be extra absorption of zinc oxide and titanium dioxide than we thought however that has not been confirmed utilizing precise sunscreen mineral filters, that are very totally different than uncooked zinc and titanium. That is essential as a result of absorption breaks down the UV filter simply because it does with chemical sunscreens. It doesn’t matter what the mechanism of motion of mineral sunscreens, we advocate reapplication each 2 hours throughout sustained solar publicity.
What’s the proof that chemical sunscreen will not be protected?
The security of chemical sunscreen has come into query with a examine printed within the Journal of the American Medical Affiliation in 2019 and a second examine printed in 2020.
- Chemical sunscreen is quickly absorbed via the pores and skin into the blood below regular utilization circumstances. The primary examine confirmed that 4 of the chemical sunscreen filters current in 4 commercially out there sunscreens are readily absorbed into the blood stream throughout the course of regular advisable use/reapplication throughout a seashore vacation. The blood ranges exceeded the FDA’s protected degree by as early as day 1 and remained excessive for as much as 7 days after discontinuing using the sunscreen. The second examine confirmed one other 6 chemical UV filters from 4 commercially out there sunscreens did the identical factor.
- Some chemical sunscreens have been present in breast milk, together with oxybenzone and octocrylene.
- Oxybenzone/benzophenone has additionally been detected in amniotic fluid (fluid surrounding the newborn in a pregnant girl).
- Research recommend oxybenzone/benzophenone and octyl methoxycinnamate (OMC) could also be hormone disruptors and oxybenzone could also be a carcinogen. Each are widespread chemical sunscreen filters.
- The FDA has stated that solely the 2 mineral lively sunscreen components are acknowledged as protected and efficient, these are the bodily sunscreen UV filters zinc oxide and titanium dioxide. All others, that means all chemical sunscreen UV filters, want additional examine.
What are the environmental implications of chemical sunscreens?
Sunscreen components enter the setting after we swim and bathe, the place they wash off into aquatic environments and waterways. A number of the important sunscreen components used as we speak which can be recognized to hurt marine life embrace oxybenzone/benzophenone, nano-titanium dioxide and nano-zinc oxide, octinoxate, oxtocrylene. The picture here’s a real-life instance of the potential quantity of sunscreen in an aquatic ecosystem. If every of those bathing go well with carrying beachgoers utilized the requisite 1 ounce of sunscreen each 2 hours to stop sunburned pores and skin throughout this seashore vacation, you’ll be able to think about how a lot sunscreen is on this water!
It’s also essential to know that a few of these chemical sunscreen components, equivalent to octocrylene and benzophenone, are additionally utilized in private care and meals merchandise that aren’t sunscreens.

What chemical sunscreen components do you have to look out for and undoubtedly keep away from?
I might undoubtedly advocate you keep away from sunscreens with oxybenzone/benzophenone. Hawaii has already banned sunscreens that include oxybenzone due to its implication in coral bleaching.
Are there chemical sunscreens I can advocate?
I choose mineral sunscreens which can be comprised of non-nano measurement particles. Expertise has superior to the purpose that there at the moment are invisible pure mineral sunscreens which can be simple to make use of equivalent to my Sheer Power Pure Bodily Sunscreens. The expertise to make an incredible pure mineral sunscreen, particularly a pure zinc oxide sunscreen, is NOT cheap. I believe the advantages far outweigh the associated fee.
That stated, some individuals nonetheless choose chemical sunscreens as a result of they’re much less more likely to have a white forged and infrequently extra economical in contrast with the most recent invisible mineral sunscreen expertise. I choose solar protecting clothes and the high-tech invisible mineral merchandise, but when one needs to make use of a chemical sunscreen as an alternative of a mineral sunscreen then I like to recommend two based mostly on seeing them work effectively for my sufferers in actual life utilization:
- The mix of the chemical sunscreen octinoxate with zinc oxide which works very well, normally rubs in fairly clear, and limits the chemical publicity to only one chemical UV filter. An choice I used for years in my observe is Citrix SPF 40 Water Resistant Sunscreen. My sufferers and household used this for years till we had Sheer Power Pure Bodily chemical free choices.
- Ecamsule in Mexoryl SX or XL. These merchandise include ecamsule, a patented UV filter owned by L’Oreal and unique to their manufacturers below La Roche-Posay together with their Anthelios merchandise.
The opposite chemical sunscreens are normally mixture of no less than 3 or 4 chemical UV filters and I’ve seen so many of those merchandise fail to guard my sufferers in actual life utilization conditions; I see shock sunburns, tanning and darkening of freckles – all of which point out DNA pores and skin harm.
The underside line with chemical sunscreens:
It is my opinion that I wish to keep away from them. I like to recommend that you just learn sunscreen labels and use solely pure mineral merchandise. I solely use pure mineral merchandise. I mix them with carrying solar protecting clothes and searching for or creating shade to guard my pores and skin. It is what I like to recommend for everybody and what my daughter and her younger household do to guard the valuable pores and skin and well being of my toddler granddaughter.
