Full list of ingredients: estriol, C12-15 alkyl benzoate, caprylic/capric triglyceride, cetyl alcohol, ethylhexylglycerin, glycerin, glyceryl stearate, hydroxyethyl acrylate/sodium, acryloyldimethyl taurate copolymer, oleic acid, olea europaea (olive) fruit oil, PEG-100 stearate, phenoxyethanol, dimethicone, polymethylsiloxane, water (aqua), stearic acid, trolamine, vitamin E acetate.
Who is it for: M4 was made for women in perimenopause and menopause—the life stages when hormonal changes start to visibly affect the skin, causing dryness, fine lines, and loss of radiance.

How to get it: Prescription required. A menopause-trained doctor will review your medical history to determine if this is the right treatment for you.

Did you know?
Up to 30% of dermal collagen is lost in the first 5 years of menopause—with another 2.1% lost every year after.

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.
