Reviews Summary
Customers say this serum has a lightweight, easily absorbed texture that works well on their skin. Many reviews mention reduced facial oil and redness, with frequent users noting improvements in skin texture. The serum pairs well with other skincare products, though some find it needs time to dry between layers. While most experience positive results, a few report sensitivity or breakouts. Reviews particularly highlight its effectiveness for oily skin concerns and many mention becoming repeat purchasers.

    My skin feels clear after using it

    I had acne for a while and it was difficult finding products that actually worked without making my skin super dry or flaky, but this was really nice! I eventually stopped using it since my skin has become more clear, but I was very happy with it when I did use it!

    Soothing before retinol

    This serum is great to use before retinol. It soothes my skin and it’s brightening. It really helps with redness. It seems to go a long way because of the texture, you don’t need a lot to cover your face.
