Hand calluses, also called calluses, can be removed through the use of exfoliators, removal with a knife, and reduction of friction. A callus is a limited thickening of the stratum corneum caused by prolonged pressure or friction on the skin of the hand, which is manifested by the appearance of a limited, flat, waxy-yellow patch. If the callus is thick enough to cause pain, or if you find it unsightly, you can usually soak the callus in hot water to soften it, and then use a knife to chip away the over-keratinized callus. This treatment is usually done in a hospital, and it is important to minimize excessive pressure and friction on the skin of the hand. Alternatively, exfoliators such as salicylic acid ointment and urea ointment can be used to soften and remove the callus. If the callus is mild, it can be gradually relieved to disappear simply by reducing excessive pressure and friction on the skin of the hand. General hand callus if there is no discomfort symptoms, can not be dealt with, its for the skin has a certain protective effect. If you want to deal with callus, it is recommended to consult a doctor in a timely manner, under the guidance of the doctor to deal with, in order to avoid improper handling damage to the skin. Drugs need to be used in accordance with medical advice.
