Detailed answer

Skin brighteners can be used on hands to help reduce dark spots, uneven skin tone, and improve overall brightness. However, it is important to choose a product specifically formulated for the hands and to follow the instructions provided. Look for ingredients like vitamin C, kojic acid, or licorice extract which can help to lighten and brighten the skin. Apply the skin brightener to clean, dry hands and massage it in gently until fully absorbed. Remember to follow up with a broad-spectrum sunscreen during the day to protect your hands from further sun damage.
