    Sticky

    "I bought this with the wash, exfoliator, and a couple oils, sunscreen. Also a light tinted foundation I was suckered to buy to go with the sunscreen for "added coverage", my wet n wild tinted moisturizer is better than that stuff. There's already tint in the sunscreen Skin better I was told to buy. In combination it's an oily mess for my already oily skin. Silk plus makes my skin sticky with the night routine of the milky wash lotion, p50 tone lotion, and 2 serums, then after my water based moisturizer I add silk plus and it's sticky and oily. . . waste of money. . . snake oil. Don't waste your money. One plus, WELL HYDRATED, best suited for DRY skin, not oily."

    Beautiful finish

    "I think this is my favorite finishing serum because you can do so much with so little. 2-3 drops over your moisturizer and if feels like you've locked in hydration leaving your skin looking glassy and beautiful."

    "I ordered the Serum Silk Plus and about 4 other serums in the . 3 oz size. The containers are so small and with some, it is hard to get the liquid out. The Serum Silk seems good and I will continue to use it. My favorite product on your line is the P50 1970 and the U Lait. Truly amazing!"
