Great! Let’s dive into Chemical Sunscreens — what they are, how they work, and whether they’re right for your skin.
π What Are Chemical Sunscreens?
Chemical sunscreens use active ingredients that absorb UV radiation, convert it into heat, and release it from the skin. They're formulated to blend seamlessly into the skin — no white cast, no chalkiness.
π¬ How They Work
Unlike mineral sunscreens that sit on top of the skin and reflect UV rays, chemical sunscreens penetrate the skin’s surface and absorb UV rays before they can damage your cells.
π§ͺ Common active ingredients include:
-
Avobenzone (UVA protection)
-
Oxybenzone
-
Octinoxate
-
Octocrylene
-
Homosalate
These are often combined to offer broad-spectrum protection (UVA + UVB).
