We tapped the specialists and did some digging so that you’ve all of the info earlier than making a choice.
What Is Chemical Sunscreen?
Chemical sunscreens use chemical compounds to forestall UV rays from coming into your pores and skin by absorbing the rays with a chemical response. “Every time a UV ray causes this response, the molecule of chemical sunscreen is destroyed,” explains Bailey. “It is likely one of the causes that you must reapply sunscreen throughout extended solar publicity—principally, you run out of chemical sunscreen molecules in your pores and skin as they block the solar’s UV rays.” Mineral sunscreens do the identical factor, however they use mineral particles to forestall UV rays from coming into your pores and skin with a mixture of absorbing, scattering, and reflecting the rays.
“Chemical sunscreen additionally wants time to bind together with your pores and skin earlier than it begins working. That is one purpose why we suggest making use of sunscreen 15-Half-hour earlier than solar publicity. This time permits the product to soak up into the highest layer of your pores and skin the place it’ll work,” says Bailey.
Is Chemical Sunscreen Secure?
A few of the substances in chemical sunscreens may be controversial, and because of this, many individuals keep away from utilizing them and follow mineral sunscreens. As a result of chemical sunscreens are absorbed into the pores and skin, they have an inclination to have a lighter formulation than bodily sunscreens. Nonetheless, additionally they are inclined to have extra chemical substances to supply broad-spectrum protection from UV rays, together with preservatives, dyes, and fragrances, which might trigger pores and skin irritations.

Bailey, however, has a extra skeptical take relating to chemical sunscreens. “Over the course of my profession, I’ve seen chemical sunscreens fail to supply dependable UV safety for my sufferers below actual use situations,” she says. “I see shock sunburns, tanning, and darkening of freckles throughout their pores and skin exams—all of which point out DNA pores and skin harm.”
“Bodily sunscreens, however, have confirmed far more dependable,” Bailey continues. “The FDA has mentioned that solely two energetic sunscreen substances are acknowledged as protected and efficient: These are the bodily sunscreen UV filters zinc oxide and titanium dioxide. All others, which means all chemical sunscreen UV filters, want additional research. I don’t suggest chemical sunscreens. That mentioned, they’re fashionable and higher than no sunscreen in any respect.”
So, whereas chemical sunscreens are extra available, and infrequently don’t depart a white solid, it’s essential to learn the substances label. “Secure substances to search for in sunscreen are titanium dioxide and zinc oxide,” says Peredo. “Each are protected for the atmosphere. Particularly, zinc oxide acts as a barrier on the pores and skin’s floor and is oftentimes gentler for those who have delicate pores and skin. It is best to keep away from PABA and trolamine salicylate, two chemical compounds that are actually not often utilized in sunblock.”
Moreover, you must look out for avobenzone, octinoxate, mexoryl SX, tinosorb S, and tinosorb M, as they might be dangerous.

“A few of the foremost sunscreen substances used at present which can be recognized to hurt marine life embrace oxybenzone (benzophenone), nano-titanium dioxide and nano-zinc oxide, octinoxate, and octocrylene,” warns Bailey.

Then that you must enhance the frequency of functions.”
In keeping with Bailey, the mix of the chemical sunscreen ingredient octinoxate with zinc oxide works very well, often rubs in fairly clear, and limits the chemical publicity to only one chemical UV filter.
For the face, Peredo recommends Alastin’s HydraTint Professional as a result of it has a chemical block and tint that provides you an additional layer of safety as a result of it displays the solar. Plus, it evens the pores and skin tone. It’s light-weight, supplies broad-spectrum safety, and is oil-free and fragrance-free, so it received’t break you out.
