Multi-Peptide Lash and Brow Serum
A lightweight peptide-based serum created to support denser, fuller-looking lashes and brows.
A strong choice for someone who wants a prostaglandin-free lash and brow serum with a more treatment-style ingredient approach.
It's an affordable entry point into lash serums without the prostaglandin concern. The ingredient list is more sophisticated than most drugstore lash serums — multiple peptides, extracts, and Biotinoyl Tripeptide-1 is actually well-studied for hair follicle support.
Apply to clean, dry lash line and brow area before your eye cream or moisturizer. The serum should be the first product on that area after cleansing. Both morning and night applications are recommended.
Someone with naturally sparse brows who wants a low-risk, treatment-style product to incorporate into their daily routine without concerns about prostaglandin side effects.
If you expect fast, dramatic results — this is a slow-build product. Also, if you're applying too much product, excess migrating toward the eye may cause irritation. A thin, precise layer is better than heavy application.
The formula is gentle — if you experience eye irritation, you're likely applying too close to the eye or using too much. Adjust application precision before stopping completely.
- A nourishing eye cream applied after it
- Consistency matters more than anything you pair it with — use it every day
- Brow oil at night for additional conditioning
Best For
- Sparse-looking brows
- Thinner-looking lashes
- Lightweight lash/brow serum
- Prostaglandin-free option
How to Use
Apply a thin layer to clean, dry lash line and brow area twice daily, morning and night.
Key Ingredients
Stimulates the expression of keratin genes in lash and brow follicle cells, theoretically supporting the production of stronger, denser hair. Used in professional-grade and mass-market lash/brow serums.
Supports the extracellular matrix surrounding hair follicles, aiming to improve the environment that keeps hair anchored and in an active growth phase.
Attracts and retains moisture, soothes irritated skin, supports barrier repair, and improves skin texture and softness.
May stimulate cell renewal and growth factor signaling pathways. In lash/brow serums, targeted toward supporting the hair follicle growth environment.
Supports the anchoring environment of hair follicles and works synergistically with other scalp peptides to promote a healthier follicle matrix.
Constricts blood vessels (reduces puffiness and dark circles), provides antioxidant protection, and stimulates scalp circulation when used in scalp serums.

About This Product
The Ordinary Multi-Peptide Lash and Brow Serum uses a combination of peptides — including Myristoyl Pentapeptide-17 and Biotinoyl Tripeptide-1 — alongside plant extracts to visually support lash and brow density. The formula is prostaglandin-free, making it a safer option compared to some lash growth serums that have been associated with iris pigmentation changes.
