Lash Serum

What is a lash serum?

A lash serum is a liquid treatment that you apply with a fine brush directly along the lash line. It supplies lashes and hair roots with caring ingredients so that they look stronger, fuller and healthier. Most serums can be used on your brows too.

What ingredients do lash serums contain?

• Peptides such as palmitoyl pentapeptide-4 or acetyl hexapeptide-8 care for the hair root and support lash elasticity.
• Biotin (vitamin B7) is one of the best-known hair care ingredients.
• Panthenol and hyaluronic acid add moisture and make lashes more supple and less brittle.
• Newer formulas contain exosomes or copper peptides.

Good to know: some lash serums on the market contain prostaglandin analogues such as isopropyl cloprostenate. They can strongly stimulate growth but may also cause eye irritation and discolouration of the eyelid skin. If you have sensitive eyes, it’s worth checking the ingredient list. The lash serums in our range rely on caring ingredients such as peptides, biotin, panthenol and hyaluronic acid.

How to use a lash serum

1. In the evening, remove make-up thoroughly and let the eye area dry.
2. Sweep the brush once, thinly along the upper lash line – like eyeliner. Less is more: too much serum can run into the eye.
3. If you like, treat the lower lash line very sparingly.
4. Take out contact lenses first and let the serum absorb for a few minutes.

Patience pays off: lashes grow slowly. You’ll usually see first changes after four to eight weeks of daily use and the full result after about three months.

Who is a lash serum for?

• thin or short lashes
• lashes that have become brittle from curlers, extensions or lash lifts
• sparse brows

Stop using the serum if your eyes are red, itchy or inflamed. Sudden heavy loss of lashes or hair should be checked by a doctor.

What does the research say?

The effect of prostaglandin analogues on lash growth is well studied – they were originally used as eye drops for glaucoma. For cosmetic lash serums with peptides and biotin, most studies come from the manufacturers. Large independent studies are still lacking.
