Science-backed ingredients

What is Estriol?
Estriol is one of three forms of estrogen our bodies naturally produce, until menopause. Once we hit menopause, we lose up to 30% of our dermal collagen in the first five years alone. And it only goes down from there. The solution to losing estrogen is replenishing it, and that's where estriol comes in.
Research shows that topical estriol can address hormonal aging and helps keep skin resilient, youthful, and balanced. Topical estriol stays on the surface of your skin and doesn’t enter your bloodstream, making it safe for everyday use.

What is Tretinoin?
Tretinoin as a topical skin treatment isn’t new. It’s been used to treat mild to moderate acne for almost 50 years. Tretinoin is also known as retinoic acid, and it’s the generic name for synthetic vitamin A.
Anti-Aging Rx Tretinoin is a prescription-strength topical cream or gel that is used mainly to treat acne, fine lines, hyperpigmentation, and discoloration. Tretinoin is able to speed up the life cycle of skin cells, making them divide faster and die faster, so newer, healthier cells can take their place.
