BACKGROUND The efficacy and safety of nonablative fractional laser for acne scars treatment has been described in several studies. [] Key MethodMETHODS Forty-six patients with atrophic facial acne scars were randomized to microneedling and laser groups, receiving 3 sessions performed monthly. Two blinded dermatologists applied the validated "Quantitative Global Grading System for Postacne Scarring" scale, before, 2 months, and 6 months after the treatment.

Efficacy of Microneedling Versus Fractional Non-ablative Laser to Treat Striae Alba: A Randomized Study
TLDR
NAFL and MN are safe for treating SD, particularly in individuals classified as phototype III or IV, and MN is a useful non-technology-dependent, low-cost alternative therapy for SA.
Clinical and histopathological comparison of microneedling combined with platelets rich plasma versus fractional erbium-doped yttrium aluminum garnet (Er: YAG) laser 2940 nm in treatment of atrophic post traumatic scar: a randomized controlled study
TLDR
Microneedling could be as effective as a fractional laser when combined with PRP and when used for more sessions, but there was no significant difference in improvement neither between groups I and II nor between groups II and III.
Combined use of microfocused ultrasound and a calcium hydroxylapatite dermal filler for treating atrophic acne scars: A pilot study

TLDR
Combining MFU-V and diluted CaHA is effective for treating atrophic acne scars, and a clear trend was apparent with the greatest improvement observed among subjects with severe scars.
A systematic review of treatments for acne scarring. Part 2: Energy-based techniques
TLDR
No standardised scale is available for acne scarring, leading to variability in evaluation and interpretation of data in different studies, and there is an overall lack of high-quality evidence about the effects of different interventions.
A Combination Approach to Treating Acne Scars in All Skin Types: Carbolic Chemical Reconstruction of Skin Scars, Blunt Bi-level Cannula Subcision, and Microneedling-A Case Series.
TLDR
The triple combination of CROSS, subcision, and microneedling appears to be effective for the treatment of acne scars, with consistently high satisfaction among patients and photographic evidence of improvements.
Skin needling for the treatment of acne scarring: a comprehensive review.
TLDR
Microneedling is a useful treatment for acne scarring and when combined with other treatments such as autologous platelet-rich plasma (PRP), chemical peels, filler injections or laser treatment, a greater improvement was reported.
Adverse Events of Nonablative Lasers and Energy-Based Therapies in Subjects with Fitzpatrick Skin Phototypes IV to VI: A Systematic Review and Meta-Analysis.
TLDR
The overall rate of adverse events in nonablative laser and energy-based therapies for SPTs IV to VI is low, but the incidence of postinflammatory hyperpigmentation (PIH) is not insignificant.
Fractional Laser Photothermolysis in the Treatment of Skin Defects: Possibilities and Effectiveness (Review)
TLDR
The review presented here illustrates the high efficacy of the application of both ablative and non-ablative fractional laser photothermolysis for wrinkles reduction, for general improvement of the skin appearance, for the abnormal pigmentation treatment, and the removal or appearance improvement of atrophic scars from acne as well as in areas of skin stretching.
Microneedling of Scars: A Large Prospective Study with Long-Term Follow-Up.
TLDR
The clinical results obtained in this study support the use of microneedling for various facial and non-facial scars across a broad range of skin phototypes with minimal risk of adverse effects.
A systematic review of treatments for acne scarring. Part 1: Non-energy-based techniques
TLDR
Post-acne scarring is a common and challenging condition with no easy and definitive solution, and treatment with PPMA led to improvement in 84% of patients, and dermal fillers also led to favourable outcomes.

Fractional nonablative 1,540-nm laser resurfacing of atrophic acne scars. A randomized controlled trial with blinded response evaluation
TLDR
The nonablative 1,540-nm fractional laser improves acne scars with a minimum of adverse effects and five of the ten patients evaluated their acne scars as moderately or significantly improved.

TLDR
Atrophic scars can be effectively and safely reduced with 1,550-nm erbium-doped fiber laser treatment, and improvement scores increased proportionately with each successive laser session.

TLDR
It is concluded that nonablative fractional photothermolysis is a safe and effective treatment for moderate or severe acne scarring.
Do combined alternating sessions of 1540 nm nonablative fractional laser and percutaneous collagen induction with trichloroacetic acid 20% show better results than each individual modality in the treatment of atrophic acne scars? A randomized controlled trial
TLDR
Combined alternating sessions of both modalities of 1540 nm nonablative fractional laser in alternation with PCI and TCA 20% in the treatment of atrophic acne scars shows better results than each individual modality.
Second‐Generation 1,550‐nm Fractional Photothermolysis for the Treatment of Acne Scars
TLDR
Fractional photothermolysis is a safe and efficacious treatment modality for the treatment of all types of acne scars of all severities and in patients with Fitzpatrick Skin Types III to V.
Efficacy of the Fractional Photothermolysis System with Dynamic Operating Mode on Acne Scars and Enlarged Facial Pores
TLDR
It is suggested that the fractional photothermolysis system (FPS) with dynamic operating mode may provide a new treatment algorithm in some cases with acne scars and enlarged pores.
Fractional Resurfacing for the Treatment of Atrophic Facial Acne Scars in Asian Skin
TLDR
The introduction of fractional photothermolysis of atrophic facial acne scars resulted in significant improvement even in a single treatment, with good satisfaction and unremarkable side effects.
Fractional laser resurfacing for acne scars: a review
TLDR
This review investigates the effectiveness of ablative and nonablative fractional photothermolysis (FP) lasers for treating facial acne scars and finds that a higher proportion of patients who underwent ablative FP experienced postinflammatory hyperpigmentation (PIH) than those who hadNonablative FP.
Which Type of Atrophic Acne Scar (Ice‐pick, Boxcar, or Rolling) Responds to Nonablative Fractional Laser Therapy?
TLDR
Using an objective evaluation tool, an erbium‐doped glass laser was found to improve atrophic acne scars, markedly so for boxcar and rolling scars.
Fractional photothermolysis: Current and future applications
TLDR
Fractional photothermolysis (FP) produces arrays of microscopic thermal wounds called microscopic treatment zones (MTZs) at specific depths in the skin without injuring surrounding tissue and represents an alternative for treatment of dermatologic conditions without the adverse effects of ablative laser devices.
