Low-tech Treatments for Acne Scarring: CROSS, Subcision, and Injectables

Dermatologists routinely treat acne with the objective of preventing acne scarring. Once control of acne has been achieved, our patients are often keen to improve textural skin changes such as atrophic acne scars. We often equate the management of atrophic acne scars with the need to reach for high-tech devices such as resurfacing lasers or radiofrequency-microneedling. While these modalities can play a pivotal role in resurfacing the skin, low-tech treatments can also be used in monotherapy or combination treatment to improve specific types of acne scars. In this article, we discuss the CROSS technique, subcision, and the use of injectables for acne scars.
