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 forestall 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.

When a sunscreen has solely chemical UV filters it’s solely a chemical sunscreen.
How are you aware what’s in your sunscreen?
You discover the lively UV filters listed on the again label of each sunscreen.
The FDA requires sunscreens to have again labels which might be titled ‘Drug Information’.
Energetic Elements: The primary part on a sunscreen Drug Information again label lists the “Energetic Elements”, that are the UV filters.
Inactive Elements: All the different components, together with the bottom (cream/lotion/gel/liquid and so on.) and different components akin to nutritional vitamins and antioxidants, are known as “Inactive Elements”. They’re listed on the backside of that label. They aren’t thought-about ‘lively’ in terms of sunscreen.
I’ve really useful mineral sunscreens over chemical sunscreens for over 20 years.
I really useful zinc oxide sunscreens to my sufferers beginning in 1999 when a nice type of invisible zinc oxide grew to become accessible. 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 offers the very best, most steady and trusted safety based mostly on doing tons of of hundreds 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 trade 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 Skilled 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 now have even higher zinc oxide sunscreen expertise than we did again in 1999.

Decrease the quantity of uncovered pores and skin by sporting solar protecting clothes on as a lot of you as you might be keen to cowl then A.S.Okay. your self in case your uncovered pores and skin is satisfactorily – and safely – protected.

I’ve made it my precedence to supply the fitting vary of pure mineral non-nano particle sunscreens for each day in our lives;
Pure Zinc Sunscreens:
Zinc Oxide and Titanium Dioxide Mineral Sunscreens
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 steadiness 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 in accordance with 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 it’s essential 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 along with your pores and skin earlier than it begins working. That is one purpose why we suggest 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 would work.
What separates chemical sunscreen from bodily sunscreen?
Bodily sunscreen, additionally known 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. In addition they work to some extent by absorbing the rays.
It has lengthy been thought that almost all of their safety comes from bouncing the rays off of pores and skin. Not too long ago, a laboratory research 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 completely different than uncooked zinc and titanium. That is necessary 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 suggest reapplication each 2 hours throughout sustained solar publicity.
What’s the proof that chemical sunscreen is probably not secure?
The security of chemical sunscreen has come into query with a research revealed within the Journal of the American Medical Affiliation in 2019 and a second research revealed in 2020.
- Chemical sunscreen is quickly absorbed by way of the pores and skin into the blood underneath regular utilization circumstances. The primary research confirmed that 4 of the chemical sunscreen filters current in 4 commercially accessible sunscreens are readily absorbed into the blood stream in the course of the course of regular really useful use/reapplication throughout a seashore vacation. The blood ranges exceeded the FDA’s secure stage by as early as day 1 and remained excessive for as much as 7 days after discontinuing the usage of the sunscreen. The second research confirmed one other 6 chemical UV filters from 4 commercially accessible 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 secure 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 research.
What are the environmental implications of chemical sunscreens?
Sunscreen components enter the atmosphere once we swim and bathe, the place they wash off into aquatic environments and waterways. A number of the primary sunscreen components used as we speak which might be identified to hurt marine life embody 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 swimsuit sporting beachgoers utilized the requisite 1 ounce of sunscreen each 2 hours to forestall sunburned pores and skin throughout this seashore vacation, you possibly can think about how a lot sunscreen is on this water!
It is usually necessary to know that a few of these chemical sunscreen components, akin to octocrylene and benzophenone, are additionally utilized in private care and meals merchandise that aren’t sunscreens.
What are the commonest chemical sunscreen UV filters?

What chemical sunscreen components do you have to look out for and positively keep away from?
I might positively suggest you keep away from sunscreens with oxybenzone/benzophenone. Hawaii has already banned sunscreens that comprise oxybenzone due to its implication in coral bleaching.
Are there chemical sunscreens I can suggest?
I choose mineral sunscreens which might be produced from non-nano measurement particles. Expertise has superior to the purpose that there at the moment are invisible pure mineral sunscreens which might be simple to make use of akin to my Sheer Energy Pure Bodily Sunscreens. The expertise to make a terrific pure mineral sunscreen, particularly a pure zinc oxide sunscreen, is NOT cheap. I feel the advantages far outweigh the price.
That stated, some folks nonetheless choose chemical sunscreens as a result of they’re much less prone to have a white solid and infrequently extra economical in contrast with the newest invisible mineral sunscreen expertise. I choose solar protecting clothes and the high-tech invisible mineral merchandise, but when one desires to make use of a chemical sunscreen as a substitute of a mineral sunscreen then I like to recommend two based mostly on seeing them work nicely for my sufferers in actual life utilization:
- The mix of the chemical sunscreen octinoxate with zinc oxide which works very well, often rubs in fairly clear, and limits the chemical publicity to only one chemical UV filter. An choice I used for years in my follow is Citrix SPF 40 Water Resistant Sunscreen. My sufferers and household used this for years till we had Sheer Energy Pure Bodily chemical free choices.
- Ecamsule in Mexoryl SX or XL. These merchandise comprise ecamsule, a patented UV filter owned by L’Oreal and unique to their manufacturers underneath La Roche-Posay together with their Anthelios merchandise.
The opposite chemical sunscreens are often mixture of a minimum of 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 injury.
The underside line with chemical sunscreens:
It is my opinion that I need to keep away from them. I like to recommend that you simply learn sunscreen labels and use solely pure mineral merchandise. I solely use pure mineral merchandise. I mix them with sporting 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 dear pores and skin and well being of my toddler granddaughter.
