Who is it for?


Our skincare solutions are for anyone looking to reverse the effects of estrogen-deficiency in the skin due to menopause, perimenopause, or just aging (loss of collagen, decreased elasticity and moisture, and appearance of wrinkles), and for those looking to treat acne, fine lines, hyperpigmentation, and discoloration. We formulated M4 Face Cream and Tretinoin Face Cream with women just like us in mind!

Science-backed ingredients:


Learn about the key ingredients in M4 Face Cream.



Increases collagen production, retains and restores skin moisture, increases skin firmness, decreases pore size, decreases wrinkle depth, and increases skin elasticity.



Attracts moisture and locks it into the top layer of the skin, leaving it more hydrated.


Vitamin E:

Stops skin from losing moisture, protects cells from UV damage, and helps soften skin.


Learn about the key ingredients in Tretinoin Face Cream.



Speeds up cell turnover.



Reduces the appearance of blemishes and brightens your overall skin tone.



Helps moisturize and soothe your skin.

The routine:

  • Adding M4 to your morning or nighttime skincare routine is easy. You can replace your current moisturizer and firming creams with M4 or add it to your regime. Just apply one pump of M4 to the face and neck.
  • Follow it up with Tretinoin: Apply a pea-sized amount (about ½ pump) using your fingers to your forehead, cheeks, and chin, avoiding your eyelids and the corners around your mouth and nose. Start by using every other night, and after a few weeks of use, increase to nightly as your skin tolerates it.
  • Remember to always complete your morning routine with an SPF!

By the numbers:

Aging skin

Did you know that up to 30% of dermal collagen is lost during the first 5 years of menopause? It decreases by an additional 2.1% every year after. And, did you know that tretinoin provides epidermal thickening by up to 30%?
