RETINOL TIPS from Dr. Koo
USE IT AT NIGHT
Retinol is naturally photo-unstable so it breaks down in sunlight, making it less effective. Nighttime use is most effective.
APPLY TO CLEAN, DRY SKIN
Apply retinol to clean skin, after cleansing, for maximum absorption.
BE CONSISTENT
Consistent application of your Retinol is how you get results.
PAIR WITH VITAMIN SERUM
Apply Vitamin Serum after Retinol to boost its effectiveness—and see quicker results.
