About this sunscreen
Hawaiian Tropic Silk Hydration Continuous Spray SPF 15 is a chemical spray on an older-school base of Homosalate, Octocrylene, Butyl Methoxydibenzoylmethane, and Ethylhexyl Salicylate. It leaves a matte finish with a low white cast and a lightweight feel, and works well under makeup, but it is flagged as likely to sting the eyes. The low breakout-trigger reading suggests it is generally fine for blemish-prone skin. With a 63.7/100 score, the modest SPF 15, and good protection, it suits light exposure more than intense sun.
