Caire is designed for women 40 and up, experiencing dramatically changing skin -- the sags, bags, volume loss, elasticity loss, drier skin, menopausal acne and deeper creases and folds -- that are the signatures of hormone-caused skin aging. Did you know that estrogen/progesterone Hormone Decline actually starts at 40, well before actual menopause? Caire is at the forefront of a movement to rethink quality of life products for ‘grown up’ women. Their expertise is skin; and their editor-loved Theorem Serum + Triple Molecule Mask features PhD-invented Triple Hyaluronic Acid Complex.
