This product is specially designed to solve the white cast and fake pale problems of traditional sunscreens, focusing on an "invisible zero-trace" finish on the face. The formula adopts a highly soluble organic UV filter compound system, replacing traditional large-particle powders that easily cause white cast. It is completely transparent and colorless after application, leaving no white residue, mask-like effect or grey tone on all skin tones including yellow-dark skin and deep skin tones, truly suitable for all skin tones.With SPF 50 and PA+++, it provides long-lasting broad-spectrum UV protection for daily commuting and short outdoor activities. The product has a sheer essence lotion texture, as light as water to the touch. It forms a film quickly after spreading, with no greasiness after film-forming. It does not stick to masks or hair, leaving the skin with a natural and transparent original texture. The formula has passed hypoallergenic testing, free of alcohol, fragrance and artificial pigments, gentle and non-irritating, safe for all skin types including sensitive skin. When paired with base makeup, it fits smoothly without pilling or caking, and can be used as a pre-makeup sunscreen base without affecting the finish and staying power of subsequent makeup. Suitable for people who pursue burden-free skin feel, dislike sunscreen white cast, and need sunscreen for daily commuting and makeup base.
