Detailed answer

Hand cream can help with dark elbows caused by friction by providing hydration and promoting healing. It can also soothe and nourish the skin, reducing inflammation and preventing further damage. However, hand cream may not be effective for hyperpigmentation, which is caused by an overproduction of melanin. Hyperpigmentation typically requires targeted treatments such as topical creams containing ingredients like hydroquinone or kojic acid, chemical peels, or laser therapy. It is advisable to consult with a dermatologist to determine the best course of treatment for hyperpigmentation on the elbows.
