Frequently Asked Questions
What is the 'Sandwich Method' for using Tretinoin after 40 without dryness?
After cleansing at night, apply a thin layer of ceramide moisturizer first, wait 10 minutes until dry, apply a pea-sized dot of Tretinoin, and seal with moisturizer again.
Can I combine prescription Tretinoin with an estriol face cream?
Many women over 45 use topical estriol cream (from Alloy or Musely) in the morning for plumpness/hydration and prescription Tretinoin 3 nights a week for cellular turnover.
