Reviews Summary
Customers say this serum helps control excess oil throughout the day. Many notice reduced shine on their T-zone and longer-lasting makeup. While some experience immediate results, others report it takes a few weeks to see benefits. The texture absorbs quickly for most users, though some mention a white residue if not properly blended. Reviews indicate it works particularly well for very oily skin types. Several note improved skin texture and smaller-looking pores with continued use. The product layers well with other skincare items, though some prefer using it mainly in targeted areas.

    Definitely reduces excess oil

    I like this product. It does what it claims. I use it daily and will reorder. The only thing is after I apply this and then my lotion and then my sunscreen I notice a flakiness. I dont think it's do to this but my lotiin that has niacinamide and glutathione in it . I am not sure if applying all these ingredients is causing the crumbling of what I applied. It's not dry skin. Anyway I tried is without my lotion with just sunscreen on top and it works fine. Does not flake. I do need to blott on hot days but it keeps my skin looking less oily. I highly recommended it and will be purchasing it again.
