Detailed answer

Night creams are typically designed to address concerns related to the face, such as moisturizing, anti-aging, or acne. Underarm darkness, also known as hyperpigmentation, can be caused by various factors such as shaving, friction, or hormonal changes. It is important to identify and address the underlying cause of the darkness. While night creams can provide hydration and nourishment to the skin, they may not contain specific ingredients or formulations to target and lighten underarm darkness. Consult with a dermatologist who can recommend appropriate treatments or procedures such as laser therapy, chemical peels, or topical lightening agents specifically formulated for underarm hyperpigmentation.
