Rimmel Wonder’Serum Lash & Brow Serum, Clear 0.37oz — Strengthens and Stimulates Growth, Slim Mess-Free Brush

Rimmel Wonder’Serum is a conditioning lash and brow serum designed to strengthen, nourish, and support the appearance of fuller lashes and brows with a precision, mess-free applicator.

This lightweight, clear serum combines a nutrient-rich complex — including bamboo extract, biotin, peptides, and castor oil — to help condition fragile hairs and reduce breakage. The formula is designed for overnight use and features a super-slim brush to make targeted application simple and tidy. Clinically tested for conditioning benefits and formulated to be gentle on sensitive eyes, Wonder’Serum can be paired with your favorite Rimmel mascaras or brow products for enhanced eye definition.

How will this serum fit into my nightly routine?

Apply the serum to clean, makeup-free lashes and brows once a day, ideally at night, to let the conditioning complex work while you sleep. The slim brush delivers an even, controlled line along the lash base and brow hairs without smudging.

• Use after cleansing and removing all eye makeup.
• Two or three light strokes along the upper lash line per eye.
• Brush lightly through brows where you want extra conditioning.
• Leave on overnight; no rinsing required.

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

The serum blends plant-derived and cosmetic actives chosen to condition and protect hair. Bamboo extract and biotin help fortify the hair fiber, while peptides and castor oil contribute to resilience and smoothness, minimizing the look of breakage.

• Bamboo extract for structural support and surface conditioning.
• Biotin to help maintain hair strength and tensile resilience.
• Peptides to support healthy-looking hair appearance.
• Castor oil for added softness and reduced brittleness.

Is the application safe for sensitive eyes and compatible with mascara?

The formula is developed to be gentle and is suitable for sensitive eyes when used as directed. Because it dries clear and has a fine applicator, you can use it alongside mascara routines; apply serum at night and mascara during the day for best results.

• Clear, non-tinted formula minimizes visible residue.
• Slim brush prevents product smears on lids and lashes.
• Works with daily makeup — serum overnight, mascara day.
• Follow packaging guidance if you have specific eye conditions.

Who is this for? Rimmel Wonder’Serum suits anyone seeking to improve the look and condition of natural lashes and brows without adding color or heavy oils. It’s a good option for people with fragile or thinning hairs who want a simple, low-effort add-on to their beauty routine, especially those who prefer targeted, mess-free application and overnight treatment. Ideal for makeup-lovers who plan to pair a conditioning serum with their daily mascara or brow styling products.
