Love your extensions but worried about what's happening underneath? You can absolutely use a lash serum with extensions on. Done right, it supports your natural lashes while your set looks full, so you get the best of both.

Can you use a lash serum with eyelash extensions?

Yes. A peptide lash serum is designed to work on bare lashes or under extensions, so you do not need to take a break from your sets to keep up your routine. The goal is simple: condition and support the natural lashes carrying your extensions, so your base stays healthy between appointments.

Extensions sit on your own lashes, and your own lashes shed and regrow on their natural cycle. Looking after that natural base is what keeps your sets sitting well and your lash line looking dense even on the days you go without extensions.

How do you apply lash serum when you have extensions?

Apply a thin line along the upper lash line once daily on clean, dry lashes, just as you would on bare lashes. The serum goes on the skin at the base of your lashes, not down the length of the extensions, so it targets your natural lashes without soaking the bonds.

A few habits make this easier with a set on:

• Apply at night after cleansing, once your lash line is fully dry.
• Use the smallest amount that traces the lash line. More product is not better and can leave residue near the bonds.
• Let it dry completely before bed so nothing transfers to your pillow.

Follow the once-daily routine for 1 to 12 weeks, then drop to 2 to 3 times per week to maintain. If you want to read the full routine and ingredient detail, here is the peptide-based Lash Population growth serum and how it works.

Will a lash serum affect how long my extensions last?

Used as directed, a thin line along the lash line keeps product away from the extension bonds, so your routine and your sets can coexist. The serum is applied to the skin at the base, not to the adhesive points or the length of the lashes.

To protect your bonds while you use a serum, keep oils and heavy creams away from the lash line, avoid rubbing your eyes, and let the serum dry fully before sleeping. If you ever have questions about your specific adhesive, check with your lash artist, who can tell you what plays nicely with their products.
