About this sunscreen
Belif Dew Guard Glow Boost Serum SPF 40 is a chemical SPF serum built on avobenzone, homosalate, octisalate, and octocrylene. It keeps a balanced finish, stays lightweight, and shows low white cast, with low breakout risk and an okay fit under makeup. It does carry a higher chance of stinging if it reaches the eyes, so caution near the eye area is wise. Good protection and a 63.1/100 score make it a reasonable everyday serum-style SPF.
