Lightweight Sunscreen Formula for Acne-Prone Skin SPF 50+ PA++++

Based on the discussion, the staff recommended a formula for a lightweight sunscreen suitable for acne-prone, easily clogged, combination skin that provides SPF 50+ and PA++++ protection.

Here is the suggested formula:

• Water: Remaining (approx. 82.5%)
• SPF Protect Ultra II: 10%
• Tris-Biphenyl Triazine (Nano): 5%
• Mild Preserved Eco: 1%
• Satin Cream Maker: 1.5%

Mixing Steps:

1. Combine Water, Mild Preserved Eco, and Satin Cream Maker. Add Tris-Biphenyl Triazine (Nano) and blend until uniform. Heat this mixture to 70°C.
2. Heat SPF Protect Ultra II to 70°C.
3. Slowly add the hot mixture from step 1 into the hot SPF Protect Ultra II from step 2 while stirring until fully combined.

This formula uses modern sunscreen filters designed to provide high protection while aiming for a lighter texture compared to formulas heavy in physical filters or oil-soluble chemical filters requiring significant solvents.
