Long, full lashes without expensive extensions or layers of mascara? According to our Eves members, a good lash serum is the ultimate hack. Especially if you naturally have short, fragile lashes or damage from extensions, curlers, or makeup. But how does a lash serum actually work? And what should you look out for? The experts at Syrene fill us in.

A lash serum is a lightweight liquid that you apply daily along your upper lash line. The formula is often packed with powerful ingredients such as peptides, biotin and prostaglandin analogues. These nourish the hair follicles, strengthen the lashes and support their natural growth cycle. In short: a lash serum helps your lashes grow longer, fuller and stronger.

Yes! If you use it correctly and choose a serum with the right ingredients, you’ll often see results after 4 to 8 weeks. The most powerful formulas contain prostaglandin analogues or growth factors – these stimulate the lash growth cycle and boost both length and volume. Peptides help make your lashes stronger and thicker, while plant extracts improve circulation around the follicles. So always check the ingredients carefully! Serums containing only oils or biotin are great for nourishment, but rarely deliver a true lash glow-up.
