Chemical Sunscreens Vs. Physical Sunscreens: Which Is Better?

Understanding Sunscreens: Chemical vs. Physical

Sunscreens protect your skin from harmful UV rays, and there are two main types: chemical and physical (mineral). Each works differently, so choosing one depends on your skin’s needs and your preferences.

Chemical Sunscreens

• How They Work: Absorb UV rays, turn them into heat, and release it from your skin.
• Key Ingredients: Avobenzone, octocrylene, octinoxate, oxybenzone.
• Pros: Lightweight, blends easily, no white residue.
• Cons: May irritate sensitive skin; some ingredients harm coral reefs.

Physical Sunscreens

• How They Work: Sit on the skin’s surface and reflect UV rays.
• Key Ingredients: Zinc oxide, titanium dioxide.
• Pros: Gentle on sensitive skin; safer for the environment.
• Cons: Thicker texture, can leave a white cast.

How to Choose

• Skin Type: Chemical sunscreens work for most skin types, but physical ones are better for sensitive or reactive skin.
• Texture Preference: Chemical sunscreens are lighter; physical ones can feel thicker.
• Environmental Impact: Physical sunscreens are generally reef-safe, while some chemical ones aren’t.

The Bottom Line
The best sunscreen is the one you’ll use daily. Look for a broad-spectrum formula with SPF 30 or higher, and reapply often.
