It also improves skin hydration, making it smoother and more youthful. Alloy M4 is particularly beneficial for women experiencing menopausal skin changes. However, this cream can worsen hyperpigmentation, dark spots, sun spots and melasma. Do not use if you are a pigmented Baumann Skin Type. This cream requires a prescription, ensuring it is used safely and effectively under medical supervision.
