About the Product

What it is: Lip plumper, 7 ml. Safe & clean. Suitable for all skin types, OS-01 LIP MASK is fragrance-free, non-comedogenic, and cruelty-free (Leaping Bunny certified). Dermatologist-tested and awarded the National Eczema Association Seal of Acceptance.

What Else You Need to Know:

  • Powered by the os-01 senescence-blocking peptide: Works at the cellular level to target thinning, aging lips at the source, restoring visible fullness and smoothness over time.
  • Restore fullness & smoothness: Visibly reduces the appearance of fine lines and wrinkles on the lips, for more resilient, fuller-looking lips over time.
  • Overnight deep hydration: Lips stay hydrated for hours, with lasting moisture retention that builds over time. The rich, non-sticky formula melts in and works while you sleep.
  • Directions: Using the reusable metal applicator, apply a generous layer onto clean, dry lips. For a deep treatment, apply before bed and leave on overnight.
