ABSTRACT
Scarring that result from acne is a very distressing and difficult problem for physician and patient alike. The type of scarring following acne eruptions is also variable and each type requires a different treatment strategy. Subcision techniques or skin needling in conjunction with non-ablative lasers may be used in patients presenting milder to slightly more severe scarring. The morphology of each scar must be assessed and treatment designed accordingly. Scarring occurs in all types of acne, not linked tonodulocystic disease, but does vary with the severity and delay until effective treatment is organized. Therapeutic intervention for post-acne scarring has historically been limited by the considerable morbidity of most treatments for only marginal disease improvement. Options and treatment algorithms for dealing with post-scar scarring are explored and a systematic review of literature is performed. Hypopigmented macular scarring also called perifollicular scarring has been reasonably refractory to treatment.
