How to Use ISDIN K-Ox Eyes Correctly: Apply a Small Amount (Grain of Rice) with the Cooling Applicator in Your Skincare Routine

Using the product correctly ensures you get the most out of its benefits. Here’s a step-by-step guide:

1. Cleanse your face: Start with a clean, dry under-eye area. Avoid applying other products (like serums) before this treatment to maximize absorption.

2. Dispense the right amount: A little goes a long way. The amount should be applied is about the size of a grain of rice.

3. Apply with the applicator: Gently pat the cream around the eye contour using the ceramic applicator. Its cooling effect helps reduce puffiness instantly while delivering a firming effect.

4. Gently extend the product: Use your finger to lightly tap and smooth it over the under-eye area until fully absorbed. This ensures the delicate skin under the eyes receives even coverage.

5. Wait before makeup: If applying makeup, wait 2–3 minutes for the product to set and protect skin from moisture loss.

Common mistakes to avoid:

• Using too much product (can irritate sensitive eyes).

• Rubbing aggressively (can cause unnecessary tugging on delicate skin).

• Applying to wet skin (dilutes the formula and reduces effectiveness).

• Skipping cleansing and before using the treatment (can lead to clogged pores).
