La Mente Stem Cells Eyelush Serum — Lash Growth Serum with Stem Cell Extracts, 4 g
La Mente "Eyelush" Serum is a Japanese cosmetic lash serum developed with stem cell culture technology and a blend of bio-active peptides targeting the appearance of fuller, longer-looking lashes. The formula combines two types of stem cell culture extracts (including stem cell-derived exosomes) with growth-factor peptides — oligopeptide-1 (EGF-like), oligopeptide-13, and oligopeptide-5 — designed to work at the lash root zone to support the hair growth cycle visually. The lightweight gel-serum is applied to the lash line at the root, not to the lash body, making it a precision lash-care treatment rather than a cosmetic sealer or mascara. Results are described by La Mente as becoming visible after 30 days of consistent use. See also Japanese eye care products and anti-ageing care essentials.
Note on the name "Eyelush": "Eyelush" is La Mente's intentional product name (a portmanteau of "eye" + "lush") — not a spelling error. The product targets lash lushness and density, hence the name.
Cosmetic disclaimer: This is a cosmetic product, not a pharmaceutical or quasi-drug (医薬部外品). Claims relating to "stem cells" and "growth factors" refer to cosmetic ingredients in this product — they do not constitute medical claims or guarantees of hair regrowth. Individual results vary.
Key Benefits
- ✓ Dual stem cell culture extracts + stem cell-derived exosomes — La Mente uses two types of stem cell culture conditioned media alongside exosomes (30–200nm extracellular vesicles carrying bioactive molecules, mRNA, and proteins) as conditioning agents to support the lash follicle environment in cosmetic use.
- ✓ Oligopeptide-1 (EGF-like peptide) — a growth-factor-derived peptide widely used in premium cosmetic formulations to support the appearance of cell turnover in the follicular zone; this is a cosmetic active, not pharmaceutical EGF.
- ✓ Oligopeptide-13 + Oligopeptide-5 — complementary lash-conditioning peptides in the La Mente formula that support the look of hair density and resilience when applied to the lash root area.
- ✓ Hydrolyzed Keratin — the primary structural protein of the hair shaft; hydrolyzed (low molecular weight) keratin penetrates the lash cuticle to reinforce and condition existing lash fibres, reducing brittleness and breakage.
- ✓ Swallow's Nest Hydrolysate (Hydrolyzed Swallow's Nest Extract) — a premium Japanese beauty ingredient derived from the nest of Aerodramus swiftlet birds; rich in glycoprotein sialic acid compounds used in high-end anti-ageing and hair care cosmetics.
- ✓ Sodium Hyaluronate — hydrates the delicate lash-line skin and conditions the follicle environment; supports a comfortable application experience with no tugging.

Who Is This For?
- Anyone experiencing thin, sparse, brittle, or short-looking lashes who wants a cosmetic serum to support the appearance of fuller, healthier lashes without the commitment of lash extensions.
- People who have noticed lash thinning due to age, hormonal changes, or overuse of eyelash curlers and heavy mascara and are looking for a targeted cosmetic maintenance step.
- Those interested in advanced Japanese cosmetic biotechnology — stem cell culture technology, exosomes, and oligopeptide complexes represent premium cosmetic innovation.
- Anyone wanting to reduce dependence on lash extensions or lash-building procedures through daily preventative lash care.
- ⚠️ Contains Placenta Extract (source unspecified by La Mente — potentially equine, porcine, or plant origin) — not suitable for those avoiding placenta-derived ingredients; not suitable for confirmed vegans; AR customers: see halal FAQ below.
- ⚠️ Contains Swallow's Nest Extract — bird-derived ingredient; patch test recommended for those with bird-protein sensitivities.
How to Use
- Remove eye makeup thoroughly; cleanse the eye area gently.
- Open the Eyelush Serum and use the precision brush applicator to apply a thin line of serum along the base of the upper lash line — as you would apply eyeliner, but without extending past the natural lash line.
- Allow to dry completely (1–2 minutes) before applying any other product or closing your eyes.
- Can be used on the lower lash line if desired, though the primary focus is the upper lashes where follicle density is highest.
- Do not apply directly onto the lash body or mascara-coated lashes.
Frequency: Once daily, preferably at night as the final step in your evening skin care routine, or in the morning before eye makeup. Consistent daily use for a minimum of 30 days is recommended to evaluate results.

FAQ
What does "stem cell" mean in a cosmetic product — are there living stem cells in this serum?
No — cosmetic "stem cell" products do not contain living cells. In this serum, the "stem cell" components are: (1) a conditioned medium — a filtered aqueous solution in which stem cells were cultured, containing secreted proteins, peptides, and growth factors; and (2) exosomes — microscopic vesicles (30–200nm) released by stem cells during culture, carrying bioactive molecules including mRNA, proteins, and lipids. These conditioned media and exosome preparations are then purified and stabilised into the cosmetic formula. There are no living cells in the final product. All claims relate to cosmetic conditioning benefits.
What is "Eyelush" — is that a typo of "eyelash"?
No — "Eyelush" is La Mente's intentional brand name for this product, combining "eye" + "lush." It is a portmanteau designed to evoke the look of lush, abundant lashes. The serum itself targets eyelash density and fullness, hence the name. La Mente also produces the "Eyelush" name on packaging and in their marketing materials.
How long will results take and what can I realistically expect?
La Mente states that visible results appear after approximately 30 days of consistent daily use. This aligns with the natural hair growth cycle, during which a new lash takes approximately 4–8 weeks to grow from the follicle. As a cosmetic (not a pharmaceutical), results are individual and depend on baseline lash condition, consistency of application, and individual follicle activity. This serum supports the look of lash fullness and conditions existing lashes — it is not a medically proven hair regrowth treatment.
Can I use this serum while wearing contact lenses?
We recommend removing contact lenses before applying any lash serum near the lash line, and waiting at least 15 minutes after application before reinserting lenses. The precision brush applicator allows targeted application, but the proximity to the eye requires extra care. If the serum enters the eye, rinse with water immediately.
Is this serum suitable for use with eyelash extensions?
We do not recommend using this serum on top of lash extensions. Cosmetic serums and their conditioning ingredients (particularly polyols and humectants) can interfere with lash extension adhesive. If you have extensions and wish to use a lash serum, apply only to the base of the natural lash where the extension has not bonded, and consult your lash technician first.
Is the Placenta Extract in this serum halal and is the product vegan?
The product contains Placenta Extract, which can be derived from equine (horse), porcine (pig), bovine (cow), or plant sources. La Mente does not specify the source of the placenta extract in publicly available documentation. This means: (1) Vegans should not assume this product is vegan without confirming the placenta source with the manufacturer. (2) Muslim customers: If the placenta is porcine-derived, the product would not meet halal requirements for many scholars. If equine or bovine-derived, opinions differ — consult your religious authority. No halal certification is issued for this product. We recommend contacting La Mente directly for clarification on ingredient origin if this is important to you.
