In dermatology, cotton gloves are used to enhance the absorption of creams and ointments for conditions like eczema, psoriasis, and dermatitis by creating a barrier that locks in moisture and prevents the product from wiping off. They provide comfort to sensitive skin, can be worn over medicated treatments overnight to moisturize dry or cracked hands, and some are specifically designed with soft, seamless, unbleached cotton for superior comfort and reduced irritation.
