This serum is truly a must have and has transformed my skin completely. I mix this with the Glow Serum for glowing, plump, hydrated skin.
This is the best serum ever! My fine lines are diminishing. My husband noticed and started using my youth serum so I had to buy him his own.
If I could only choose one SP product to have in my arsenal, this would be it. Youth Serum helps me in keeping my skin clear of blemishes and my perpetually dry skin moisturized. Overwhelmingly recommend this product!
