No7 Lash Impact Lash Serum — Lash & Brow Treatment 6.1ml, Visible Fuller Thicker Darker Lashes

No7 Lash Impact Lash Serum is a nightly brow and eyelash treatment designed to visibly enhance the look of fuller, thicker, and darker lashes with consistent use over eight weeks.

This concentrated 6.1ml serum from No7 is formulated to be used along the lash line and on brows to improve the appearance and definition of both lashes and eyebrows. It’s lightweight, suitable for all hair and skin types—including sensitive skin—and is intended to be applied nightly for the most noticeable results. The formula is made to complement your eye-makeup routine by creating a stronger base that helps lashes and brows look more defined.

How quickly will I notice a difference in my lashes?

Many users report initial improvement in lash appearance after a few days to weeks thanks to immediate conditioning and enhanced definition. For more pronounced visible change—fuller, thicker, and darker-looking lashes—follow nightly application for about eight weeks. Individual results vary depending on natural lash cycle and consistent use.

• Visible conditioning within days for smoother, glossier lashes
• Noticeable fuller and darker look typically after 6–8 weeks of nightly use
• Best results with continuous application as directed

Can I use the serum on both my eyebrows and eyelashes?

Yes — the product is formulated for dual use on lashes and brows to improve the overall look of hair density and darkness. Apply sparingly along the base of the lashes and along sparse brow areas. The design supports targeted application where you want more definition or the appearance of volume.

• One brush for precise application along lash line and brow hairs
• Helps create the look of fuller brows when applied to sparse areas
• Works under makeup as a nourishing base for eye looks

Is this appropriate for sensitive skin and daily use?

No7 formulates this serum to be compatible with all skin types, including sensitive skin, when used as directed. Start with nightly application and discontinue if irritation occurs; consult a professional for persistent reactions. Because the texture is lightweight and non-greasy, it layers well beneath mascara and brow products.

• Suitable for sensitive skin when patch-tested first
• Nightly application recommended for sustained results
• Non-greasy finish that layers with makeup

How should I apply the serum for best results?

Apply the serum once daily, preferably at night, to clean, dry skin and lashlines. Use the applicator sparingly to draw a thin line along the base of the upper and/or lower lashes; for brows, apply to sparse areas following the natural shape. Consistent nightly use promotes the most visible improvement over an eight-week period.

• Cleanse face and dry the eye area before application
• Use the brush to apply a thin line along the lash base and to fill sparse brows
• Allow to dry before applying other products; nightly use recommended

Who is this for? No7 Lash Impact Lash Serum is intended for anyone seeking the appearance of more defined lashes and brows without changing their makeup routine. It’s a practical choice for people with naturally fine, light, or sparse lashes and brows who want a non-invasive cosmetic boost. If you prefer a nightly, low-effort treatment that supports a more noticeable lash and brow look over weeks, this serum is built for that daily habit. Avoid use if you have known sensitivities to the product ingredients; when in doubt, perform a patch test or consult a dermatologist.
