After raising a child and entering your 40s, oil and moisture are lost simultaneously, making your skin thin and prone to sagging. Beyond simply applying products, you need an "elasticity lifting" routine that restores skin density. For cleansers, we recommend a moisturizing milk or oil-based cleanser rather than a thick one. For the base step, generously use a highly concentrated ampoule containing peptides or EGF, which are effective in enhancing elasticity. For creams, choose a rich, oily formula rather than a gel-based one to create a strong protective layer on the skin. At the end of your evening routine, mix in a drop or two of face oil or combine it with a gua sha massage to promote lymphatic circulation and shape facial contours. This is the secret to maintaining a sagging jawline.
