This is a Tinted serum with light, dewy coverage, mineral SPF, and potent levels of skincare ingredients. I love how lightweight this serum is but my color has changed and I have not opened/used this bottle. Color is Formosa ST4 Brand New and Exp date is 11/2025 Apply this with your fingertips for the best coverage. Does leave your skin with a dewy finish which I like (not thick)
