Experimental Hybrid Fractional laser - SOC |
23 participants with fitzpatrick skin type IV-V will be in this arm. At the first visit, participants will undergo informed consent, education about the procedure, education about proper sun-care, and will be provided sunscreen. Participants will be prescribed a prescription of hydroquinone or a retinol to prevent hyperpigmentation, per standard of care. If participants choose to take this they will wait one month of taking the prescription and then begin treatment sessions. If not, participants can begin treatment sessions right away. Treatment consists of 3 laser sessions with the Sciton Halo hybrid fractional laser. Session amount depends on the degree of improvement. At each session before and after images will be collected. At each session participants will fill out the dermatology quality of life survey as well as a patient satisfaction survey. |

Experimental Hybrid Fractional laser- Non- SOC |
23 participants with Fitzpatrick skin type I-III will be in this arm. At the first visit, participants will undergo informed consent, education about the procedure, education about proper sun-care, and will be provided sunscreen. Participants will be prescribed a prescription of hydroquinone or a retinol to prevent hyperpigmentation, per standard of care.

Detailed Description
Acne is chronic inflammatory condition involving the pilosebaceous unit. One of the most common complications of acne is scarring, which occurs as a result of dermal damage during the healing process of active acne. Studies have shown that acne scarring can have a negative impact on an individual's quality of life and has been described as a risk factor for multiple psychiatric conditions including depression, anxiety, suicide, and poor self-esteem. Unfortunately, treatment of acne scarring, particularly those of the atrophic subtype, prove difficult to treat. A 2016 Cochrane review failed to provide sufficient evidence to support the first-line use of any intervention. Laser technology has been emerging as an effective, non-invasive treatment of acne scarring. Ablative lasers work by delivering energy to the dermal layer of the skin, resulting in thermal injury and stimulation of dermal cells to produce collagen, thus resolving the scar. More recently, fractional lasers, which create multiple tiny columns of thermal injury, have been introduced with the benefit of reduced downtime and adverse effects compared to ablative lasers. The fractional CO2 laser is widely used for the treatment of acne scarring, however its use is limited in patients of Fitzpatrick IV and V skin due to risk of hyperpigmentation among other adverse events. The erbium-YAG fractional laser serves as an alternative, and has shown to produce less thermal injury and thus be more well-tolerated with lower risk of adverse effects in patients. The hybrid fractional laser combines a 2940 nm wavelength with a 1470 wavelength and has an ablative component targeting the epidermis and a nonablative component targeting the dermis at the same spot. The investigators seek to investigate the Sciton Halo, hybrid fractional laser for its efficacy in treating acne scarring and tolerability in patients with a specific emphasis on those with Fitzpatrick IV and V skin.
