Most eyeliners only define your eyes for the day, then wash away without giving anything back to your lashes. Revlon ColorStay Lash Serum Liner goes further, combining precise, long-wear definition with daily lash care in one streamlined step.

This liner is powered by conditioning agents and humectants like propanediol and butylene glycol that help attract and hold moisture along the lash line. Plankton extract works alongside these to support the look of stronger, more resilient lashes with continued use. A network of modern acrylate polymers forms a flexible film that hugs the lash line for all-day wear.

The formula feels lightweight and fluid, gliding on smoothly without dragging the delicate eye area. Once set, it dries down to a defined, transfer-resistant finish that resists smudging and flaking for up to 24 hours. It maintains a flexible feel, so it moves comfortably with your skin instead of cracking through the day.

The precise tip and controlled, water-based formula make it easy to trace along the lash line, from subtle definition to bolder wings. For best lash-care benefits, apply close to the roots every day, allowing the serum-infused formula to sit where lashes need it most.

ColorStay film-forming technology locks pigment in place for up to 24 hours without smudging or transfer.Serum-infused formula with plankton extract and moisturising humectants supports the look of stronger, conditioned lashes.Water-based, lightweight texture delivers smooth, even lines without tugging the delicate lash line.Long-wear film removes with your usual cleanser, helping minimise lash breakage from aggressive rubbing.

Use this liner as your daily definition step, then follow with your preferred mascara to amplify both lash length and volume. Pair with a dedicated lash serum in your evening routine to further support the look of fuller, fortified lashes over time.

An eyeliner and lash-care step in one, it delivers precise 24-hour definition while supporting stronger-looking lashes with daily use.

• Step 1. Start with clean, dry eyelids free from oil or heavy cream.
• Step 2. Rest your elbow on a flat surface and gently lift your lid for a smoother canvas.
• Step 3. Starting at the inner corner, draw small, connected strokes along the lash line, keeping close to the roots.
• Step 4. Build intensity by layering a second pass, widening the line slightly towards the outer corner if desired.
• Step 5. Allow the formula to dry for a few seconds before blinking fully or applying mascara.
• Step 6. Use daily along the lash line to maximise the conditioning, lash-care benefits over time.

Pro Tips

• Tilt your chin up and look down into a mirror to see the lash line clearly and keep the line tight.
• For a softer effect, apply the liner, then gently diffuse the edge with a fine brush before it sets.
• If creating a wing, map the angle first with a tiny dot at the outer corner, then connect back to the lash line.
• Remove with a gentle eye make-up remover or cleanser, pressing a saturated cotton pad over the eye before wiping to help protect lashes.
