Barbi Marengo, founder of Philogeni - science-led skincare line for women in perimenopause and beyond, formulated around the skin changes that estrogen decline brings. As a certified cosmetic formulator and menopause coach, I work at the intersection of biochemistry and lived experience. The unglamorous part: every claim held to Health Canada standards, every formula tested on my own skin first. Philogeni is skincare for the evolution of midlife, made by someone living it.
