CELLMETICS BEAUTY Peptide Lash Serum for Eyelash Growth — Vegan, Gentle Night Treatment for Longer Fuller Lashes

Cellmetics Beauty Peptide Lash Serum is a vegan, gentle lash treatment formulated with a science-backed peptide blend to help lashes appear longer, fuller, and stronger with regular nightly use.

This lightweight eyelash serum pairs targeted peptides with hydrating and soothing actives to support the lash environment without irritating sensitive eyes. Designed for nightly application to clean, dry lids, the formula combines Myristoyl Pentapeptide-4 with moisturizing agents and calming ingredients to condition each hair and the skin at the lash line. It’s cruelty-free, paraben-free, and formulated to be non-irritating for mature or delicate eyes.

How quickly will I notice changes in my lashes?

Most users report visible differences in lash fullness and length within four to six weeks of consistent nightly application. Initial improvements typically show as better hydration and reduced brittleness, followed by enhanced appearance as lashes strengthen.

• Use nightly on clean lids for best results
• Expect initial conditioning within 2–3 weeks
• Fuller-looking lashes usually appear around 4–6 weeks
• Maintain with every-other-night use after results

What key ingredients are in the formula and what do they do?

The serum centers on Myristoyl Pentapeptide-4, a peptide designed to support the visible strength and length of lashes. It also contains glycerin and panthenol for deep hydration, plus allantoin and arginine to soothe and protect the delicate lash line.

• Myristoyl Pentapeptide-4 – supports lash resilience and appearance
• Glycerin & Panthenol – hydrate and reduce breakage
• Allantoin & Arginine – calm and help maintain a healthy lash base
• Vegan, cruelty-free base without parabens

Is this safe for sensitive eyes and contact lens wearers?

The formula is created to be lightweight and non-irritating, making it suitable for many people with sensitive eyes. Apply sparingly along the lash line; if you wear contacts, remove them before application and rinse immediately if irritation occurs.

• Non-irritating formulation for delicate skin
• Remove contacts before applying to lids
• Discontinue use if persistent irritation appears
• Patch-test recommended for highly reactive skin

How do I apply the serum for best outcomes?

Apply a thin line of serum along the upper lash line on clean, dry skin once each night. A precise applicator helps deliver a small amount of product to the roots so the actives can work while you sleep; reduce frequency to maintenance every other night after you reach your desired results.

• Cleanse face and remove makeup first
• One thin strip across upper lashes nightly
• Avoid getting product directly in the eye
• Switch to every-other-night to maintain improvements
