LiLash Purified Eyelash Serum 2ml is a once-daily conditioning serum designed to deliver longer, fuller-looking lashes within weeks. The slim brush-tip applicator places the formula precisely along the upper lash line, where conditioning actives — panthenol, hydrolysed lupine protein, sweet almond extract and the brand's signature dehydrolatanoprost — work to fortify and nourish the lashes for visible improvement in fullness and length. About LiLash LiLash is the flagship lash serum from Cosmetic Alchemy, a US-based brand specialising in eye-area conditioning treatments. The brand built its reputation on physician-formulated, ophthalmologist-tested products that are safe for sensitive eyes, contact lens wearers and those with lash extensions — a combination of clinical credibility and gentle formulation that's earned it cult status over more than a decade. Key benefits Longer, fuller-looking lashes — most users report visible change in 4–8 weeks, with full results in 8–12 weeks of nightly use Conditions and fortifies — panthenol penetrates both lash shafts and follicles to strengthen weakened lashes Extension- and contact-lens-safe — gentle enough to use alongside lash extensions or daily contact wear Ophthalmologist-tested — physician-formulated and tested for safety on sensitive eyes Vegan and cruelty-free — no animal-derived ingredients or testing 90-day supply — the 2ml bottle delivers approximately three months of nightly application Who it's for LiLash suits anyone with thin, sparse or short lashes — particularly those who have lost lash density through ageing, mascara wear or lash extensions. It's also a strong choice for sensitive-eye sufferers who can't tolerate harsher lash growth serums. How to use Cleanse the lash line thoroughly and pat dry; ensure the area is free of makeup or skincare residue Apply a single, thin stroke of LiLash along the upper lash line — like a liquid eyeliner — using just one stroke per eye Do not apply to the lower lash line or directly onto the lashes themselves Allow to dry for 2–3 minutes before continuing with skincare or makeup Use once daily, ideally at night. For sensitive skin, begin every other day for the first 1–2 weeks Specifications Size: 2ml (approx. 90-day supply) Format: Conditioning lash serum Application: Once daily, along the upper lash line Vegan, cruelty-free, ophthalmologist-tested Brand: LiLash (Cosmetic Alchemy)
