Learn the correct steps to apply The Ordinary's Multi-Peptide Lash and Brow Serum for thicker, fuller lashes and brows. Avoid common mistakes and see real results.

Quick Answer

Apply The Ordinary Multi-Peptide Lash and Brow Serum once daily, ideally at night, to clean, dry lash lines and brows. Use the precision applicator to draw a thin line along the upper lash line and brush brows upward. Consistency is key—visible results typically appear after 8–12 weeks of regular use.

Why Consistency Matters More Than Quantity

Lash and brow serums rely on peptides to support the natural growth cycle. Applying too much product won't speed up results—it can cause irritation or waste formula. A single, thin application per day is all you need. The Multi-Peptide complex in The Ordinary's serum is designed to be effective with minimal product, so resist the urge to reapply.

When to Apply for Best Absorption

Evening application works best because lashes and brows are at rest, and product won't be disturbed by makeup, sunscreen, or sweat. If you prefer mornings, apply after cleansing and before any other eye-area products. Wait a few minutes for the serum to dry before applying makeup or moisturizer.

Step-by-Step Application Guide

Step 1: Clean and Dry the Area: Remove all eye makeup, then wash your face and dry thoroughly. The serum must be applied to a clean, dry surface to prevent irritation and ensure absorption. Common mistake: applying over damp skin or residual makeup, which dilutes the formula. Wait 5 minutes after cleansing to ensure the skin is fully dry.
Step 2: Apply to Upper Lash Line: Dip the applicator wand once—do not overload. Draw a thin line along the base of your upper lashes, from inner to outer corner, similar to applying liquid eyeliner. One stroke per eye is enough. Common mistake: using too much product, which can cause stinging or migration into the eye. If product gets in your eye, rinse with water and skip that night's application.
Step 3: Brush Through Brows: Use the same wand to gently brush through your brows in the direction of hair growth. Coat the brow hairs lightly without saturating the skin underneath. Common mistake: rubbing the wand back and forth, which can cause shedding. For lower lashes, use a clean spoolie to dab a tiny amount along the lower lash line—avoid direct contact with the waterline.
Step 4: Let It Dry, Then Wait: Keep eyes closed for 30–60 seconds to allow the serum to dry. Do not touch or rub the area. Continue with the rest of your skincare routine, but avoid applying rich creams or oils directly over the lash line for at least 10 minutes. Common mistake: immediately layering heavy products that can block the peptides. A slight tingling sensation is normal; if it persists, reduce application to every other day.
Step 5: Use Once Daily for 8–12 Weeks: Consistency is everything. Apply every evening for at least two months before evaluating results. The peptide complex works gradually to support the hair growth cycle. Common mistake: stopping after a few weeks when no change is visible. Take a photo on day 1 and again at week 8 to track progress objectively.
