The variety of procedures used to maintain the integrity of the skin, improve its look, and treat skin disorders is known as skin care. They may involve a good diet, avoiding too much sun, and using emollients as needed. Cosmetics, botulinum, exfoliation, fillers, laser resurfacing, microdermabrasion, peels, retinol therapy, and ultrasonic skin treatment are some techniques used to improve the look. In many situations, taking care of the skin is a daily practice. Examples include treating skin that is either too dry or too wet, preventing dermatitis, and treating skin injuries.
