How it works

How to use Kosen

Kosen is a clear peptide gel that firms the look of under-eyes in about five minutes. Here's exactly how to get the best result.

  1. Applying Kosen under the eye

    Keep your face relaxed for 3–5 minutes while the film sets clear. Don't touch or squint.

Tips for the smoothest finish

  • Less is more: a thin layer dries clearest.
  • Apply after moisturizer has fully absorbed.
  • Dab it on with your ring finger. Don't rub.
  • Pat concealer on top instead of dragging it.
