Split face comparative study of microneedling with platelet rich plasma versus fractional carbon dioxide laser with platelet rich plasma in treatment of atrophic post acne scars

Abstract

Majority of the acne scars occur on the face, thus impacting the quality of life. Improvement of scars is a common request from acne patients. According to Goodman and Baron, atrophic post acne scars are graded into: • Grade 1: Macular erythematous hypo or hyperpigmented scars. • Grade 2: Mild atrophy not obvious at social distances of >50 cm or easily covered by facial make up or beard hair. • Grade 3: Moderate atrophy obvious at social distance of >50 cm; not easily covered by make up or beard hair; but able to be flattened by manual stretching. • Grade 4: Severe atrophy not flattened by manual stretching of skin.
