iS Clinical Youth Serum is designed to give skin the best of both worlds: instant smoothing and tightening, with dramatic wrinkle reduction over time. Intelligent proteins target damaged sites, strengthen the dermal structure, and instantly smooth fine lines for an immediately firmed complexion. Meanwhile, Youth Serum's safe, bio-identical growth factors gradually rebuild lost collagen to reduce fine lines and wrinkles long-term. The patented Extremozyme technology, combined with a powerful blend of antioxidants, including vitamins A, C, E and centella asiatica, encourage cellular health, provide UV photoprotection and prevent environmental damage. The result is a more youthful, vibrant and resilient complexion.
