A serum that happens to be SPF50+. TIRTIR's Air Fit Hyasis Sun Serum protects like a sunscreen and feels like skincare: a hydrating, serum-light texture with SPF50+ PA++++ that melts in with no white cast and no heaviness.
Sun cream vs sun serum
Same protection, different feel: the Sun Cream is a classic lotion finish, while this Serum version is even lighter and more hydrating, ideal if regular sunscreens feel like a layer on your skin. Both love company: cushion, makeup, or nothing at all.
Make it a routine
Apply two finger-lengths as the last morning step after moisturizer; reapply every two hours of sun exposure (the Cool Sun Cushion MINI makes over-makeup top-ups easy). Compare more in Korean sunscreen or the TIRTIR collection.
