Most lash products only make lashes look fuller while you wear them; this clear serum works behind the scenes to support the look of longer, denser lashes and brows over time. Rimmel London Lash Accelerator Lash & Brow Serum is designed for everyday use, helping fragile hairs appear stronger, smoother and more refined with consistent application.

A blend of conditioning actives and peptides is combined to support visible lash and brow improvement. Panthenol and glycerin help attract and hold moisture for softness, while hydrolysed keratin works to smooth and fortify the hair surface. Biotin, myristoyl pentapeptide-17 and biotinoyl tripeptide-1 are included to support the appearance of fuller, more resilient lashes and brows.

The formula is a clear, lightweight gel-serum that glides on easily and dries down without feeling stiff or sticky. It sits comfortably under mascara and brow products or can be worn alone overnight. Once dry, it leaves lashes and brows feeling conditioned with a natural, flexible finish that does not flake.

Use consistently morning and night on clean, dry lashes and brows for best results. The precision brush allows you to trace along the lash line and comb through brow hairs, focusing on areas that appear sparse or fragile. Allow a short drying time before applying mascara or other eye products.

Peptide complex (myristoyl pentapeptide-17 and biotinoyl tripeptide-1) supports the appearance of lash and brow density.Hydrolysed keratin helps smooth and reinforce the hair fibre to reduce the look of breakage.Humectants such as glycerin and sodium hyaluronate provide moisture for softer-feeling hairs.Clear, flexible gel texture layers comfortably under make-up without clumping or residue.

Wear the serum alone overnight, then layer your usual mascara and brow products on top in the daytime once it has dried. It fits easily into an existing eye make-up routine, acting as a conditioning base to support a more polished finish from your other lash and brow products.

• Step 1. Start with clean, dry eyes, ensuring all make-up has been thoroughly removed.
• Step 2. Using the precision applicator, apply a thin line of serum along the upper lash line, as you would an eyeliner.
• Step 3. Gently comb the serum through lashes from root to tip, coating them evenly without saturating.
• Step 4. Sweep the brush through brows, following the natural hair direction and concentrating on sparse areas.
• Step 5. Allow the serum to dry completely for a few minutes before applying mascara or brow products.
• Step 6. Use twice daily, morning and evening, for at least 30 days to see visible improvement in lash and brow appearance.

Pro Tips

• Wipe off excess product from the brush before application to avoid overloading lashes or brows.
• Focus on the roots of the hairs, as this is where support for visible growth and density is most beneficial.
• Apply in the evening as the final step of your skincare routine to maximise uninterrupted overnight contact time.
• Be consistent; keep the serum by your toothbrush or skincare to help build a regular habit.
