Store Properly: Keep the serum in a cool, dry place, away from direct sunlight, to maintain its potency.
Patch Test: Do a patch test first to ensure the serum doesn’t cause irritation.
Use Gradually: If you’re new to retinol, start with 2-3 times a week to build skin tolerance, then gradually increase frequency.
Sun Protection: Retinol can make your skin more sensitive to the sun.
Consistency: For best results, use consistently as part of your nighttime skincare routine.
