The intense Thai sun feels like a trial by fire. A major concern for beauty enthusiasts is sunscreen causing the face to "melt" or foundation to streak and cake throughout the day.

Exploring the causes of why sunscreen application can lead to"melting face" or foundation breaking down

Before looking at how to choose sunscreen, it's important to understand that the "melting face" or foundation separating happens because the textures of skincare and makeup products don't blend well. Especially, sunscreens with high oil content (oil-based) react with sweat and foundation, causing the product not to adhere properly and clump together into patches.

These days, selecting sunscreen means more than just checking SPF; consider the following checklist as well.

1. Choose a texture that suits your skin type

• For oily or combination skin: opt for gel, essence, or water-based formulas that absorb quickly and don't leave a greasy residue.
• For dry skin: select cream or milk textures that provide moisture but set quickly.
• For makeup lovers: look for products labeled "Primer Base" to help makeup last longer without melting.

2. SPF and PA ratings must meet standards

In Thailand's sun, only SPF 50+ and PA++++ offer adequate protection against UVA, which causes premature aging, and UVB, which burns the skin.
