Biotinoyl Hexapeptide-2 Amide

Our take
Is Biotinoyl Hexapeptide-2 Amide a Good Ingredient?
Evidence for visibly strengthening lashes and brows is mostly marketing-driven or small-scale, so results may be subtle, which is why it's rated Fair. Eye-area use can also pose a slight irritation risk for sensitive users.
What it does
Skin Benefits
Helps lashes, brows, and hair fibers feel conditioned and appear less brittle, supporting a fuller-looking appearance and improving the feel of density and suppleness over time; evidence for dramatic effects is limited.
Where you'll find it
Uses in Skincare & Cosmetics
Frequently formulated into lash serums, brow gels, and scalp leave-ons, and also used in conditioning mascaras and brow pomades.
Before you use it
Safety
Typically well tolerated, but peptides and eye-area formulas can cause stinging or redness in some. Patch test on the lash line perimeter first, and avoid direct contact with the eyes.
