What to expect: Skin often feels smoother and more hydrated with consistent daily use.

SMOOTH OUT THE SIGNS OF AGING

Our Filler Serum targets fine lines and wrinkles with a combination of niacinamide, hyaluronic acid, and a copper-peptide complex. With medical-grade ingredients and an advanced formula, it is built to support firmer, smoother-looking skin.

  • In a 15-day study of its NF-13 peptide complex, the look of wrinkle depth was reduced by 15% and wrinkle volume by 13%.
  • In a placebo-controlled study, the same complex produced a significant increase in a cutometer measure of skin firmness at 15 days.
  • In laboratory (ex vivo) skin-tissue testing, the complex increased elastin content by 190% over 11 days versus untreated tissue.

Ingredient Highlights

  • NIACINAMIDE

    Regulates oil production, minimizes the appearance of pores, and reduces the redness and skin inflammation.

  • PEA EXTRACT

    Rich in antioxidants, which help combat free radicals and protect the skin from oxidative stress

  • SODIUM HYALURONATE

    This gentle ingredient is responsible for keeping skin plump and hydrated, which results in younger-looking skin.
