I am in love with this mattifier! Exuviance Matte Perfection is a light, oil-free gel primer. Aside from acting as a mattifier, it also contains Mandelic Acid, a naturally occurring Alpha Hydroxy Acid (AHA) found in almonds, and Gluconolactone to improve uneven pigmentation and roughness. Mandelic Acid can also help a bit with acne.
The primer feels like most silicone primers and absorbs quickly. It can be worn alone as a mattifier and treatment product, but it also provides a nice base for makeup by filling in fine lines and smoothing the skin. When I use it I find that I tend to stay shine free for most of the day with it.
Exuviance has a real winner with this one!
