What is inside
BioPeptin Complex
The brand's trademarked blend of peptides, botanicals and lipids. Trademarking a complex is normal practice, and RevitaLash is more forthcoming than most about what sits inside it — peptides, panthenol, biotin and green tea extract all appear on the published list. Still, a trademark is a name, not a specification, and it makes the formula harder to compare like-for-like.
Panthenol, biotin and green tea
The conditioning core is familiar and sensible: humectant, vitamin, antioxidant. It is the same logic our top pick follows, executed to a high standard.
No prostaglandin analogues
The brand states the formula is free of prostaglandin analogues, which places it in the category we recommend by default.
| Brand | RevitaLash Cosmetics |
|---|---|
| Key actives | BioPeptin Complex (peptides, botanicals), biotin, panthenol, green tea extract |
| Prostaglandin analogues | Brand states the formula is free of prostaglandin analogues |
| Applicator | Fine brush applicator |
| Routine | Once nightly, upper lash line, clean dry skin |
| Typical timeline | Brand suggests looking for a change at around 6 weeks |
| Price (USD) | $100.00 — 2.0 mL; one-time purchase. Other sizes: 1.0 mL $59; 3.5 mL $152. Official source Checked September 10, 2026. USD; tax and shipping excluded. Prices may change. |
Using it
The brush is excellent — soft, tapered and precise. Apply along the upper lash line once nightly on clean skin. The texture is slightly richer than our top pick and takes a moment longer to dry.
Whatever serum you choose, the technique matters more than the brand: one thin line, upper lash line only, on skin with no make-up or oil left on it. Our application guide walks through it properly, including the two mistakes that cause most irritation.
What to expect, week by week
The brand points to around six weeks. In user reports, meaningful change clusters between weeks six and twelve, in line with the rest of the category.
Who it is for
Buy it if
- You want a prestige product with a decade-plus retail track record
- You prefer to buy in person at a counter
- You want to trial a small size before committing
Look elsewhere if
- You are price-sensitive — this is among the most expensive per millilitre
- You want maximum transparency on exact active percentages
How it compares
Formula-wise it is the closest competitor to our number one. The deciding factors are price per millilitre and applicator precision, and both go the other way.
| Serum | Lead active | Prostaglandin-free | Price (USD) | Score |
|---|---|---|---|---|
 | Multi-peptide complex | No | $59.00 3.5 mL | 9.6/10 |
| BioPeptin Complex (peptides | No | $100.00 2.0 mL | 9.1/10 |
 | Peptides | No | $68.00 2 mL | 8.9/10 |
 | Phyto-actives including mung bean and red clover extracts | No | $68.00 3 mL | 8.6/10 |
 | Peptides | No | $49.00 2 mL | 8.3/10 |
Ashley's verdict
A dependable, well-made conditioner that has earned its reputation. It sits second only because you pay a significant premium for the name, and because our top pick matches it on formula philosophy with a kinder price and, in my hands, a slightly easier applicator.
