Complete Application Guide for Optimal Results

Before You Begin

Patch Test Recommended: Before first use, apply a small amount to a discrete area of skin and wait 24 hours to check for any adverse reactions.

When to Use: Evening application is recommended for beginners. Once your skin adjusts, you may gradually increase to twice daily use.

Step-by-Step Application

Step 1: Prepare Your Serum
