A powerful outbreak of acne can often leave ugly and persistent acne marks behind. Acne can occur in various forms which include blackheads, whiteheads, and pimples. When there is a bout of acne, the underlying skin tissue undergoes significant damage. As the attack recedes, the skin goes through a repairing process, which results in permanent acne marks on face or back, depending on the affected area. Therefore, once you are affected by acne related problems, acne marks are almost inevitable. The intensity of acne marks depends on the severity of the acne problem that you have been subjected to. The greater the damage, the deeper the marks post healing.
