Can be used twice daily (AM and PM) or as directed by a physician.
Start use daily PM only, as the potent ingredients might take time for your skin to adjust, and you may experience some initial dryness, flakiness or irritation.
If you experience any irritation, gradually work up to AM and PM use.
If you don’t experience any irritation, start to use both AM and PM.
Apply 2-3 drops to your face, neck, chest, and back of hands as desired. Allow several minutes for serum to absorb before applying additional products.
