Sunscreen, Why Should We Apply It?
UV rays are the main culprit of skin aging. They can cause melasma, freckles, and even skin cancer. Sunscreen is an essential item to protect your skin from these UV rays.
Physical vs. Chemical Sunscreen: How They Work
Physical and chemical sunscreens block UV rays in completely different ways.
- Physical Sunscreen (Mineral Sunscreen): Mineral ingredients (zinc oxide, titanium dioxide) form a barrier on the skin’s surface, reflecting UV rays. It’s like a mirror bouncing off UV rays.
- Chemical Sunscreen (Organic Sunscreen): Chemical ingredients absorb UV rays and convert them into heat energy. It works like a sponge soaking up UV rays.

* Chemical Sunscreen: Some ingredients are controversial due to potential for allergies, skin irritation, and hormone disruption. It is important to carefully check ingredients, referring to EWG ratings.
## Recommendations by Skin Type
* Sensitive Skin, Atopic Skin: Physical sunscreens (zinc oxide, titanium dioxide) are recommended. They are gentle and cause less skin irritation.
* Oily Skin: Lightweight physical sunscreens or oil-free chemical sunscreens are recommended.
* Dry Skin: Physical or chemical sunscreens containing moisturizing ingredients are recommended.
