Every ingredient. Nothing hidden

  1. 1

    Lashes are made of keratin.

    Healthy-looking lashes start with the proteins they are built from.

  2. 2

    Peptides support the look of fuller lashes.

    Myristoyl pentapeptide-17 supports the keratin lashes are made of, for a thicker, fuller look.

  3. 3

    Then the rest of the formula.

    Biotin peptide, panthenol and hyaluronic acid round out the gel. More on each one below.

Our story

We almost launched a lash serum like everyone else's. Then we read the ingredient lists.

So we built ours differently: two well-known peptides in a gentle, fragrance-free gel, with every ingredient on the label. It won't work overnight. It's made to be used with patience.

Our promise

Try it for 60 days.

Use it every evening. If you don't love your lashes, we'll refund you, even on an opened tube.

  • Even on an opened tube
  • 60 days to decide
  • Duo: return the 2nd tube unopened

Questions, answered.
