Consult Evidence
Verdict: Good Peptide Formula — Bond Mechanism Unproven for Lash Growth
- Prostaglandin-free — fully SCCS/1680/25 compliant
- Contains AT-3 and MP-17 peptides (2 of Toplash's 3 core actives)
- Bond Building Technology™ strengthens existing lash fibers
- Clinical evidence is brand-commissioned consumer perception only
- No independent measured data for lash length or volume gains
- Missing BTP-1 (Toplash's follicle-preservation peptide)
- Significantly cheaper per mL (~$6.67) but less proven growth data
SCCS/1680/25 Compliant — No Prostaglandin Analogs
Olaplex LASHBOND contains no ICP (Isopropyl Cloprostenate), DDDE (Dechloro Dihydroxy Difluoro Ethylcloprostenolamide), or MDN (Methyl Amide Dinoprost). These three prostaglandin analogs were classified as "cannot be considered safe" for use in cosmetics by the SCCS Opinion SCCS/1680/25 (February 2026). LASHBOND is fully compliant, ophthalmologist-tested, and poses no iris darkening or periorbital fat atrophy risk.
What Is Olaplex LASHBOND Building Serum?
Olaplex LASHBOND Building Serum is a 4.5 mL clear lash serum that adapts the brand's patented hair Bond Building Technology™ to the eye area. Olaplex built its entire product line around one key ingredient: Bis-Aminopropyl Diglycol Dimaleate (BADGD) — a molecule that repairs broken disulfide bonds in the keratin structure of chemically damaged hair.
In LASHBOND, this bond-building core is combined with a three-peptide complex (including two peptides that also appear in Toplash: AT-3 and MP-17) and Red Clover Extract — the same phytoestrogen component found in VEGAMOUR's CAPIXYL complex. The result is a formula that works on two levels: structural strengthening of existing lash fibers via bond repair, and follicle-level support via the peptide complex. The brand is PGA-free by design and markets the serum as ophthalmologist-tested.
Bond Building vs. Growth-Cycle Activation: Two Different Mechanisms
Understanding how LASHBOND works requires distinguishing between two fundamentally different approaches to lash improvement:
Olaplex Approach: Bond Building
Structural Fiber Repair
Bis-Aminopropyl Diglycol Dimaleate repairs broken disulfide bonds in the keratin matrix of existing lash fibers. This reduces lash breakage, brittleness, and mid-shaft splits — making lashes appear longer because they retain their full length rather than snapping off. The mechanism was originally validated in bleached and chemically processed hair, not specifically in lash follicle biology.
Toplash Approach: Growth Cycle Activation
Direct Follicle Stimulation
Toplash's triple-peptide complex (AT-3 + MP-17 + BTP-1) targets the lash follicle at three distinct biological points: follicle anchoring in the dermal papilla (AT-3), keratin synthesis stimulation in the hair shaft (MP-17), and follicle bulge stem cell preservation to extend the anagen phase (BTP-1). This is a growth-cycle mechanism distinct from structural fiber repair.
Olaplex's BADGD technology has strong published evidence in hair — particularly for bleached and chemically processed hair that has experienced disulfide bond breakage. However, healthy, uncoloured lash hairs have significantly fewer broken disulfide bonds than bleached scalp hair. The extent to which bond repair drives meaningful growth results in typical lash use has not been independently studied. The mechanism is sound for conditioning; its specific contribution to lash length gains in a controlled setting remains unvalidated.

Peptide Overlap: What Olaplex Shares With Toplash
Olaplex LASHBOND uses three peptides. Two of them are identical to peptides in Toplash's triple-peptide complex. The critical difference is the third peptide in each formula:
| Peptide | Olaplex LASHBOND |
Toplash | Role |
|---|---|---|---|
| Acetyl Tetrapeptide-3 (AT-3) | ✅ Yes | ✅ Yes | Follicle anchoring via laminin-332 |
| Myristoyl Pentapeptide-17 (MP-17) | ✅ Yes | ✅ Yes | Keratin synthesis stimulation |
| Palmitoyl Pentapeptide-83 Amide | ✅ Yes | ❌ No | Lash retention / ECM support (Olaplex-specific) |
| BTP-1 (Biotinoyl Tripeptide-1) | ❌ No | ✅ Yes | Follicle bulge stem cell activation; extends anagen phase (Toplash-specific) |
| Trifolium Pratense (Red Clover) | ✅ Yes | ✅ Yes (via AT-3) | Phytoestrogen; DHT inhibition; CAPIXYL component |
Both serums share the two foundational growth peptides. Olaplex adds Palmitoyl Pentapeptide-83 for retention. Toplash adds BTP-1, which specifically extends the anagen (active growth) phase by activating follicle stem cells — the key differentiator for sustained lash lengthening.
Clinical Evidence: Consumer Perception vs. Measured Results
Olaplex conducted a 12-week brand-commissioned consumer perception study with the following self-reported outcomes:
- 94% reported more voluminous-looking lashes
- 97% reported longer and denser-looking lashes
- 100% reported thicker-looking lashes
- Results based on "2 weeks" for conditioning improvements; "4 weeks" for fuller/longer appearance
Perception studies measure how users feel about their lashes, not how lashes actually changed. Without photographic measurement, digital caliper data, or trichoscopy before and after, it is impossible to confirm whether lash length increased by 1 mm or 5 mm. Brand-commissioned studies also carry inherent design bias. By contrast, Toplash's independent clinical trial (conducted by a third-party research organisation) used digital image analysis to measure actual lash length (+52.3%) and volume (+31.9%) at 8 weeks — providing objective, peer-reviewable data rather than subjective survey results.

Side Effects & Safety Profile
Olaplex LASHBOND has a notably clean safety record across its reviews. Because it contains no prostaglandin analogs, it carries none of the major side effects associated with PGA-based serums:
- No iris darkening risk — absent in all prostaglandin-free formulas
- No periorbital fat atrophy — a documented side effect of PGAs including ICP and DDDE
- No skin discolouration — a common complaint with ICP-based serums (e.g., GrandeLASH-MD)
- Ophthalmologist-tested — suitable for contact lens wearers per brand claims
- Free from fragrance, oils, silicones, parabens — low allergenic potential
The most commonly noted user concern is mild eye area sensitivity for those with very reactive skin, related to the preservative system (Phenoxyethanol + Chlorphenesin + multiple organic acid preservatives). Users with known sensitivities to these preservatives should perform a patch test.

| Size available | 4.5 mL | 3 mL |
On price: Olaplex LASHBOND is significantly cheaper per mL (~$6.67 vs ~$16.63). This reflects both product positioning and the lower cost of the bond-building formula relative to Toplash's concentrated triple-peptide complex. If budget is a primary concern and you want a safe, PGA-free peptide-containing serum, LASHBOND is a genuine option. However, if measurable lash growth with independent clinical validation is your goal, Toplash offers a meaningfully stronger evidence base.
🔬 Want Independent Clinical Evidence for Lash Growth?
Olaplex LASHBOND is a safe, peptide-containing option — but it relies on a brand-commissioned perception study and a bond-building mechanism not independently validated for lash growth. Toplash's triple-peptide formula (AT-3 + MP-17 + BTP-1) has been evaluated in an independent clinical trial with digital measurement, not just self-reported perception scores.
- ✅ Independent trial: +52.3% lash length, +31.9% volume at 8 weeks
- ✅ Contains BTP-1 — the anagen-extending peptide absent from LASHBOND
- ✅ 98% of participants recorded visible change by Day 21
- ✅ Fully SCCS/1680/25 compliant — no prostaglandins
Frequently Asked Questions
Does Olaplex LASHBOND actually grow lashes?
Olaplex LASHBOND can improve the look of lashes. A 12-week brand-commissioned consumer perception study reported 97% of users saw longer-looking lashes. However, this was a perception survey — there are no independently published measurements of actual lash length or volume change. The serum's bond-building technology was originally developed for hair, and its specific contribution to lash growth has not been independently validated. The peptides (AT-3, MP-17, Palmitoyl Pentapeptide-83) do have published follicle-supporting evidence, but the combination has not been measured in a controlled, independent lash-specific trial.
Is Olaplex LASHBOND safe? Does it contain prostaglandins?
Yes, Olaplex LASHBOND is prostaglandin-free and SCCS/1680/25 compliant. It contains no ICP (Isopropyl Cloprostenate), DDDE, or MDN — the three prostaglandin analogs classified as "cannot be considered safe" in EU cosmetics by the SCCS Opinion of February 2026. The serum is ophthalmologist-tested and poses no iris darkening or fat atrophy risk. It is a safe choice for users concerned about prostaglandin side effects.
What is Bond Building Technology in LASHBOND?
Olaplex's Bond Building Technology is based on the ingredient Bis-Aminopropyl Diglycol Dimaleate (BADGD) — the company's patented active originally developed to repair broken disulfide bonds in chemically damaged hair. Applied to lashes, it works as a structural strengthener, bonding to disulfide bridges in the keratin of existing lash fibers. This reduces lash breakage and brittleness, making lashes appear fuller and healthier. It does not directly stimulate follicle activity or accelerate the anagen growth phase the way peptide complexes specifically do.
How does Olaplex LASHBOND compare to Toplash?
Both are prostaglandin-free and SCCS-compliant. Olaplex LASHBOND costs significantly less per mL (~$6.67 vs $16.63). Toplash contains three growth-specific peptides (AT-3, MP-17, BTP-1) backed by an independent clinical trial showing +52.3% lash length and +31.9% volume at 8 weeks. Olaplex shares two of those peptides (AT-3 and MP-17) but lacks BTP-1, and its clinical evidence is limited to a brand-commissioned perception survey. Olaplex's bond-building angle provides structural conditioning; Toplash's approach directly targets lash follicle activity and growth cycle support with independently measured results.
How long does it take Olaplex LASHBOND to work?
Olaplex claims users can see more conditioned-looking lashes in as little as 2 weeks, with fuller and longer-looking results appearing within 4 weeks. These timelines are based on their brand-commissioned 12-week consumer perception study. Individual results vary depending on starting lash condition and consistent application.
Can I use Olaplex LASHBOND with lash extensions?
Olaplex LASHBOND's bond-building mechanism — repairing disulfide bonds in keratin — can be beneficial for lashes stressed by extension adhesive and removal. The serum's structural strengthening may help protect natural lashes between extension appointments. It contains no oils that would break down extension adhesive. Always check with your lash technician before applying any serum near extension bonds.
What is Palmitoyl Pentapeptide-83 in Olaplex?
Palmitoyl Pentapeptide-83 Amide is a synthetic lash-conditioning peptide. The palmitoyl (fatty acid) attachment improves skin and follicle penetration. Research suggests it supports the extracellular matrix around the lash follicle and promotes lash retention — helping existing lashes stay in the anagen (growth) phase longer rather than entering telogen (shedding) prematurely. It is Olaplex's primary proprietary peptide and complements the AT-3 and MP-17 peptides also found in Toplash.
