A physical sunscreen is often heavier and thicker on the skin than a chemical sunscreen with the same SPF. Therefore, physical sunscreens might not be the best choice for oily or acne-prone skins. Additionally, mineral actives alone often offer less protection from damaging UVA radiation than chemical filters.
Which sunscreen is best chemical or physical?
The Pros of Chemical Sunscreen
Chemical sunscreens are quick and easy to apply, and unlike mineral sunscreens, they don’t leave a white film on the skin. What’s more, chemical sunscreens statistically perform better on consumer tests that look at how long they protect the skin from UV rays, Dr. Ploch says.
Why is physical sunscreen better than chemical?
While physical sunscreens work like a reflective barrier on skin’s surface, chemical sunscreens partially absorb into skin and prevent UV damage through a chemical reaction.
Why Physical sunscreens are better?
Pros of Physical Sunscreens:
You skin is protected from the sun as soon as it’s applied; no need to wait before heading outdoors. Less likely to irritate sensitive skin and better for those prone to heat-activated skin conditions such as rosacea. Longer shelf life.
Which lasts longer chemical or physical sunscreen?
Lasts longer than chemical sunscreen when exposed to direct UV light (but NOT when doing physical activities that cause the skin to get wet or sweaty) … Less likely to cause a stinging sensation or irritation, making it better for sensitive, easily-reactive skin types.
Why is chemical sunscreen bad?

What type of sunscreen is best?
Dermatologists recommend using a sunscreen with an SPF of at least 30, which blocks 97 percent of the sun’s UVB rays. Higher-number SPFs block slightly more of the sun’s UVB rays, but no sunscreen can block 100 percent of the sun’s UVB rays.
Does mineral or chemical sunscreen last longer?
Your sunscreen will theoretically last longer since they break down when they deflect UV rays! It’s a simple trick. Zinc oxide particle breakdown is slower than chemical UV filter breakdown. It’s sort of like you get more “wear and tear” from your zinc oxide product than a chemical product.
Can you apply chemical sunscreen over physical sunscreen?
