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 and instantly diminish the appearance of fine lines for an immediately firmed complexion. Meanwhile, YOUTH SERUM’s safe, bio-identical growth factors help to visibly reduce fine lines and wrinkles long-term. Our patented Extremozyme® technology, combined with a powerful blend of antioxidants, provides UV photoprotection, and helps prevent environmental damage. The result is a more youthful, vibrant, and resilient complexion.
