Does Siam Skin Retinol Day Cream leave a white cast?
White cast is rated medium, so the hybrid formula with Titanium Dioxide can leave some whiteness, which usually rubs down with effort on most skin tones.
Is the Siam Skin Retinol Lighten Day Cream SPF 30 good for oily skin or under makeup?
It is generally low on the pore-clogging scale with a balanced finish, but it is a poor base under makeup, so it suits skincare wear more than a makeup primer role.
Is Siam Skin Retinol Day Cream SPF 30 any good?
It scores 62.8/100 with good rated protection. It is a modest daily cream best suited to light wear, held back by its medium white cast and weak makeup compatibility.
