Acne is a skin concern which emerges due to the overproduction of oil by the skin’s oil glands. While the skin sebum is required to lubricate the skin, it sometimes gets trapped in blocked oil ducts, giving rise to pimples.
Hormonal changes also cause the obstruction of sebaceous glands in the skin. The damage that occurs in and around the pilosebaceous unit, during the acne process causes acne scarring.
