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.

    This is phase 1 of my miracle anti wrinkle trio

    I bought this on secret sale, just to try it or give to my teenage sons, it is not the kind of product my skin normally needs because I don't have oily skin. I also bought two more products just to try them since they were very cheep during the sale, I bought the 1% RETINOL SERUM and the 10% UREA MOISTURIZER. And then I decided to use all three as my evening routine. And that is how I discovered the best trio for wrinkles and bright skin, for mture skins. The next morning my face looks amazing!
