About the Toplash range
One formula, three sizes, and the tools that go with it. The Toplash range is built around a single prostaglandin-free peptide serum that works on both lashes and brows, sold in 2 ml, 3 ml and 6 ml so you can match the bottle to how you actually use it.
The serum uses a triple-peptide complex — MP-17, BTP-1 and AT-3 — instead of the prostaglandin analogues found in most lash serums that produce fast results. Nothing in this range contains isopropyl cloprostenate, ethylcloprostenolamide, methylamido dihydro noralfaprostal or bimatoprost. An independent 8-week clinical trial measured +52.3% lash length and +31.9% volume, with 98% of users in a consumer study seeing visible change by Day 21.
Around the serum sit the products that support the same routine: a brow gel for daytime hold, mascara and liquid eyeliner, and three precision tools — a lash comb, a curler and a slant tweezer. Two bundles pair the pieces most people end up buying together.
Not sure where to start?
Three routes, depending on what you are actually trying to fix.
Which serum size is right for you
Identical formula in every bottle. The only differences are how long it lasts and what you pay per millilitre.
| Size | Price | Per ml | Lasts (lashes only) | Best for |
|---|---|---|---|---|
| 2 ml | $29 | $14.50 | ~2 months | Brows only, or trying the formula before committing |
| 3 ml | $39 | $13.00 | ~3 months | The standard single lash course — most popular |
| 6 ml | $49 | $8.17 | ~6 months | Full course plus maintenance, or lashes and brows together |
A full result develops over 8–12 weeks, the length of one complete lash growth cycle. Running out mid-cycle is the most common reason people conclude a serum "did not work" — which is why the 6 ml suits anyone treating both lashes and brows.
Questions about the range
Which size of Toplash lash serum should I choose?
It is the same formula in all three sizes, so the choice is about how long it lasts and cost per ml. The 2 ml ($29) covers roughly two months and suits brows only or a first trial. The 3 ml ($39) is the standard single lash course — about three months of nightly use, $13.00/ml. The 6 ml ($49) works out at $8.17/ml, the lowest of the three, and covers a full course plus maintenance, or lashes and brows treated together.
What is included in the Toplash lash and brow range?
The range is built around one prostaglandin-free peptide serum in 2, 3 and 6 ml. Alongside it: a Fix & Grow brow gel, Extra Ebony mascara, a liquid eyeliner with wing stamp, and three precision tools — an eyelash comb and separator, an eyelash curler and a slant tweezer. Two bundles are also available, the Brow Serum & Gel Set and the Complete Lash & Brow Set.
Are all Toplash products prostaglandin-free?
Yes. No product in the range contains isopropyl cloprostenate (ICP), ethylcloprostenolamide (DDDE), methylamido dihydro noralfaprostal (MDN) or bimatoprost. Growth in the serum comes from a triple-peptide complex of MP-17, BTP-1 and AT-3. This matters because the EU Scientific Committee on Consumer Safety concluded in opinion SCCS/1680/25 of 2 February 2026 that ICP, DDDE and MDN cannot be considered safe for cosmetic lash and brow use.
Do I need a separate serum for lashes and for brows?
No — it is one serum for both. Apply along the upper lash line at night and along sparse areas of the brow with the same applicator. The only practical difference is quantity: brows use less product, which is why the 2 ml is often enough for brow-only use while lashes usually need the 3 ml or 6 ml.
Can the serum and the brow gel be used together?
Yes, and they do different jobs. The serum works at the follicle overnight, so it goes on clean dry skin at night. The Fix & Grow brow gel shapes and holds brows during the day. Using both is the normal routine: gel in the morning, serum at night.
How long does each serum size last?
With one nightly application along the upper lash line: the 2 ml lasts roughly two months, the 3 ml about three months, the 6 ml about six. If you treat both lashes and brows daily, each runs out noticeably sooner — in which case the 6 ml is the only size that reliably covers a full 8–12 week result window without a gap.
