About this sunscreen
Siam Scents Day Cream UV Tanaka SPF 40 is a chemical-leaning day cream that uses Titanium Dioxide with older filters Ethylhexyl Methoxycinnamate, Octocrylene, and Benzophenone-3. It has a matte finish, feels lightweight, does not sting, shows no white cast, and is low on breakout risk, so it works well under makeup. The presence of Benzophenone-3 and other older filters weighs on the rating. At 50.7/100 with moderate protection, it is a light daily day cream rather than a high-defense sunscreen.
