What it actually does

• Targets density from several directions at once. The Ordinary's stated approach is to hit multiple pathways rather than rely on a single peptide, while also nourishing and protecting the hair.
• Acetyl tetrapeptide-3 with red clover extract. This pairing — Trifolium pratense flower extract on the label — is listed as supporting how thick and dense the hair is.
• Biotinoyl tripeptide-1 with panthenol. A second combination credited with the same density and thickness support.
• Green tea, larch wood and zinc. Zinc chloride together with Larix europaea wood extract and Camellia sinensis leaf extract rounds out the third grouping, again aimed at density.
• A long exclusion list. No parabens, phthalates, mineral oil, coal tar, hydroquinone, oxybenzone, retinyl palmitate, triclosan or triclocarban; no SLS or SLES sulfates; and no formaldehyde or formaldehyde-releasing agents. Synthetic fragrance stays under one percent.
• What the testing reported. Thirty participants, twelve weeks, an outside efficacy study — those are the parameters The Ordinary quotes. Brows and lashes came out measurably denser and thicker-looking, with the brand noting that for some people the shift was already visible a month in. Small panel, brand-cited numbers; individual results vary.

How to use

1. Start clean and dry. Cleanse the area and let it dry fully before anything goes on.
2. Draw a thin line along the base of the lashes and sweep a thin layer over the brows.
3. Repeat morning and evening. It is a twice-daily treatment, and the study period was measured in weeks rather than days.

Questions

How long before I see anything?

The brand's study ran for twelve weeks on 30 people, with improvement reported from around the four-week mark for some participants. Treat that as the realistic window rather than a promise, and keep up the twice-daily routine throughout.

Can I use it on brows as well as lashes?

Yes — both areas are the intended use. The same thin layer goes along the lash line and over the eyebrows.

Does it contain a prostaglandin analogue?

The product information describes a peptide-based formula with eleven actives and does not list any prostaglandin ingredient. If you have a specific medical concern, check the full ingredient list on the pack with your doctor.

Is it vegan and fragrance-free?

It is vegan, gluten-free and cruelty-free, and arrives in recyclable packaging. Synthetic fragrance is present at under one percent rather than absent entirely.

Delivery, payment and returns?
