The purpose of this pivotal investigation is to evaluate the efficacy and safety of the Cutera enlighten multi-wavelength 532 nm and 1064 nm Nd:YAG picosecond pulse duration laser and an investigational micro-lens array (MLA) handpiece attachment for improvement of acne scars.

This is an open-label, prospective, multicenter, pivotal study in up to 45 male or female subjects, age 18 to 65 years who desire laser treatment for the improvement of acne scars. Subjects will receive up to 6 laser treatments, spaced 6 weeks (± 2 weeks) apart with the Cutera enlighten laser with the Micro-Lens Array handpiece attachment. Subjects will be contacted by phone 7 days (± 2 days) after their first treatment for follow-up. Subjects will return to the site after all study treatments have been delivered for two follow-up visits: 6 and 12 weeks (± 2 weeks) following their final study treatment.

1. The Primary Efficacy Endpoint as the correct identification of the 12 weeks post final treatment photographs from the baseline by at least two of the three blinded reviewers in 75% of the patients and an improvement of one point in the ASAS.

2. The Secondary Efficacy Endpoints as the:

   • Efficacy of the Cutera enlighten laser with the Micro-Lens Array handpiece attachment treatment as assessed by the investigator starting from the 2nd treatment onward, and
   • Subject satisfaction levels as assessed from the subject questionnaire completed at the final follow-up visit 12 weeks post final treatment.

3. The Safety Endpoint as the safety of the Cutera enlighten laser with Micro-Lens Array handpiece attachment as assessed by the frequency and severity of device related adverse events,

4. The Exploratory Analysis as the Efficacy of the Cutera enlighten laser with a Micro-Lens Array handpiece attachment for the improvement of skin quality as assessed by the investigator and/or blinded evaluators 12-weeks-post final study treatment.

Inclusion Criteria:

1. Subject must be able to read, understand and sign the Informed Consent Form.

2. Female or Male, 18 to 65 years of age (inclusive).

5. Subject has bilateral moderate to severe signs of facial acne scarring.

6. Must be willing to have Cutera enlighten laser with the Micro-Lens Array handpiece attachment treatments and able to adhere to the treatments, follow-up visit schedule, and post-treatment care instructions.

7. Willing to have very limited sun exposure and use sunscreen on the treatment area every day for the duration of the study, including the follow-up period.

8. Willing to have digital photographs taken of the treatment area and agree to use of photographs for presentation (educational and/or marketing), publications, and any additional marketing purposes.

9. Agree to not undergo any other procedure(s) or treatment(s) for acne scars during the study and has no intention of having such procedures performed during the course of the study.

2. Any type of prior cosmetic treatment to the target area within 6 months of study participation, such as laser procedures, facial fillers, i.e. (Bellafill) and those used for general aesthetic correction, facial peel, lightening creams, or facial surgery.

3. Use of prescription topicals in the treatment area within one month prior to treatment or use of topical agents one week prior to treatment that may cause facial sensitivity.

4. Suffering from significant skin conditions in the treated areas or inflammatory skin conditions, including but not limited to, open lacerations or abrasions, hidradenitis, rash, infection , or dermatitis of the treatment area prior to treatment (duration of resolution as per the Investigator's discretion).

5. Pregnant and/or breastfeeding, or planning to become pregnant. 6. Significant concurrent illness, such as diabetes mellitus, immunosuppression/immune deficiency disorders (including HIV infection or AIDS) or using immunosuppressive medication.

7. Hypersensitivity to light exposure. 8. Any use of medication that is known to increase sensitivity to light according to the Investigator's discretion.

9. History of keloid scarring, hypertrophic scarring or abnormal wound healing or prone to bruising.

10. Has a history of squamous cell carcinoma or melanoma in the treatment area. 11. History of epidermal or dermal disorders (particularly if involving collagen or microvascularity), including collagen vascular disease or vasculitic disorders.

13. History of connective tissue disease, such as systemic lupus erythematosus or scleroderma.

14. History of disease stimulated by heat, such as recurrent herpes simplex and/or herpes zoster (shingles) in the treatment area, unless treatment is conducted following a prophylactic regimen.
