Learn the correct way to apply The Ordinary Lacto-PDRN 4% + B9 Eye Cream for firmer, hydrated under-eyes. Step-by-step routine tips and common mistakes to avoid.

Quick Answer

Apply a pea-sized amount of Lacto-PDRN 4% + B9 Eye Cream to the under-eye area using your ring finger, gently tapping until absorbed. Use once or twice daily after cleansing and before heavier moisturizers.

Why the Eye Area Needs a Different Routine

The skin around your eyes is thinner and more delicate than the rest of your face. It also has fewer oil glands, which means it can dry out faster and show signs of fatigue more easily. That's why a targeted eye cream like Lacto-PDRN 4% + B9 Eye Cream is formulated specifically for this area, with ingredients that support firmness and hydration without causing irritation.

When to Apply in Your Skincare Order

Apply this eye cream after water-based serums and before heavier creams or oils. If you use a vitamin C serum or a treatment like The Ordinary Caffeine Solution 5% + EGCG, let it absorb fully first. The lightweight texture layers well without pilling, but applying it too early can dilute other active ingredients.

How to Apply Lacto-PDRN 4% + B9 Eye Cream

Cleanse and Prep: Wash your face and pat dry. If you use a toner or serum, apply it first and wait 30 seconds for it to absorb. Skipping this step can trap dirt or dilute the eye cream.
Dispense a Pea-Sized Amount: Squeeze a small amount—about the size of a pea—onto your ring finger. Less is more; using too much can cause the product to migrate into your eyes. A pea size is enough for both eyes. More product does not mean better results.
Dot Along the Eye Bone: Gently dot the cream along the orbital bone (the bone under your eye), starting from the inner corner to the outer corner. Do not apply directly on the lash line or eyelids unless the product instructions allow it. Applying too close to the eye can cause stinging or irritation.
Tap, Don't Rub: Use your ring finger to gently tap the product into the skin. Use a light, patting motion rather than dragging or rubbing. This minimizes tugging and helps absorption. Rubbing can stretch the delicate skin and reduce the product's effectiveness.
Wait Before Layering: Allow the eye cream to absorb for 30-60 seconds before applying a moisturizer or sunscreen. This prevents the layers from mixing and reduces the chance of pilling. Rushing to the next step can disturb the eye cream's film and reduce its lifting effect.
Use Consistently: Apply once in the morning and once at night for best results. Consistency matters more than quantity. Visible firmness and hydration improvements typically appear after a few weeks of regular use. Sporadic use will not deliver the visible lift the formula is designed to provide.
