Olaplex Lashbond Peptide Lash Serum — 4.5 mL clear building serum for fuller, conditioned lashes

Olaplex LASHBOND™ Building Serum is a clear, lightweight peptide formula designed to help lashes look healthier, more conditioned, and visibly fuller with twice-daily use.

Developed by Olaplex hair science experts, this ophthalmologist-tested lash serum combines a proprietary peptide complex with bond-building support, hyaluronic acid and biotin to support lash retention and the appearance of longer, thicker lashes. The fast-absorbing, clear texture is formulated without prostaglandins and is compatible with contact lenses, lash lifts, lash extensions, and false lashes. Clinical consumer testing reported visible improvements in lash appearance within weeks, though individual results may vary.

How quickly will I notice changes after using LASHBOND™?

Many users notice improved conditioning and a healthier look to lashes after just two weeks of morning and evening application. Continued nightly and morning use supports the look of increased length and fullness over a longer period.

• Conditioning and hydration visible in about 2 weeks
• Perceived length and density often reported after 4 weeks
• Twice-daily swipe for optimal, consistent results

What key ingredients deliver those lash benefits?

LASHBOND™ combines three targeted complexes: a proprietary Olaplex peptide blend to support the natural growth cycle, Olaplex Bond Building Technology to reinforce the skin barrier at the lash line, and a nourishing complex that includes hyaluronic acid and biotin to reduce dryness and brittleness.

• Olaplex Peptide Complex Technology: peptide blend to support lash retention
• Bond Building Technology: supports healthy lash-line skin for a better growth environment
• Hyaluronic Acid + Biotin: helps lashes appear hydrated and less brittle

Is this serum safe to use with common eye treatments and wearables?

The formula is ophthalmologist tested and compatible with contact lenses, lash lifts, lash extensions, and false lashes, making it suitable for a wide range of lash care routines. It is prostaglandin-free and lightweight, absorbing quickly without leaving visible residue.

• Ophthalmologist tested for compatibility
• Safe alongside lash lifts, extensions, and false lashes
• Prostaglandin-free, clear finish, quick-absorbing texture

How should I apply LASHBOND™ for best results?

Apply a single swipe along the upper lash line morning and night to clean, dry skin. Consistent application helps maintain the environment at the lash base that supports improved-looking lashes over time.

• Use on clean, dry eyelids; one swipe per application
• Apply twice daily—morning and evening—for consistent support
• Compatible with makeup and other lash services once dry

Who is this for? LASHBOND™ is formulated for anyone seeking a science-backed lash serum that prioritizes conditioning, retention and visible improvement without prostaglandins. It suits people who wear contact lenses, have lash lifts or extensions, or simply want a clear, non-irritating daily treatment to help lashes appear fuller, longer and healthier. As with any eye-area product, discontinue use if irritation occurs and consult an eye care professional for specific concerns.
