Product details

Formulated by leading board-certified dermatologic surgeon Dr. Antony Nakhla, this patented serum delivers clinical results through a proprietary technology called Peptide-Rich Plasma®—a bioidentical blend of 24 peptides, growth factors, and amino acids that mimic the molecules your skin already understands.


By signaling cells to repair, restore, and renew, the formula helps visibly improve elasticity, smooth fine lines, even tone, and reduce signs of inflammation. Additional actives deliver hydration, strengthen the skin’s barrier, and boost radiance. Designed to treat the 10 most visible signs of aging, this all-in-one treatment is a foundational step for skin that looks lifted, luminous, and visibly transformed.


INSIDE THE FORMULA

  • Peptide-Rich Plasma®: 24 bioidentical peptides, amino acids, and growth factors that stimulate deep skin regeneration
  • Hyaluronic Acid: Hydrates and plumps
  • Niacinamide: Calms redness and strengthens skin barrier
  • Glycolic Acid: Refines texture and reduces visible pores
  • Manuka Honey: Supports healing and skin immunity
  • Savage Ginger + Knotgrass Flavonoids: Provide antioxidant protection against UV, infrared, and blue light damage


CLINICAL RESULTS
After 4 weeks of use:

  • 97% saw a significant improvement in firmness and elasticity (measured via Cutometer®)
  • 100% agreed skin felt firmer and tighter
  • 100% agreed fine lines and wrinkles were visibly smoothed

    It’s too early to tell if this is effective for me or not.

    Wonderful product!

    Between that and the Resurfacing Tonic, my skin has less breakouts and has slightened the marks on my skin.

    I see absolutely no difference in my skin and for that price i should at least feel some moisture even though its a serum. Just think its a gimmick. Sticking with zo ame agistininus bader
