“…In our study, the picoseond laser demonstrated significant acne scar improvement compared to the control side ( P < .05). However, the median ECCA score improvement was 24.73% on the treatment side, which was lower than previous studies 2,7 . We suggest the reasons could be as follows.…”

“…However, the median ECCA score improvement was 24.73% on the treatment side, which was lower than previous studies. 2,7 We suggest the reasons could be as follows. First, the picosecond laser has the best effect on improving the appearance and texture of rolling scars, whereas the rolling type comprises only 15% to 25% of atrophic acne scars.…”

The 755 nm picosecond Alexandrite laser has been demonstrated to be effective and well tolerated in patients with acne scars. In this split-face, investigator-blinded study, 16 patients with post-inflammatory erythema (PIE) and acne scars were randomized to receive laser treatment on half the face, with the other half serving as a control. The treatment side demonstrated a significant improvement in both PIE and scars compared to the baseline and also when compared to the control side. Treatment was well-tolerated, with only transient and mild erythema and edema reported as side-effects. In our study, the picosecond Alexandrite laser was safe and effective in the treatment of PIE and acne scars. Comprehensive treatment outcomes should be taken into consideration when deciding on which device to use.

“…Picosecond laser for acne scars has been studied in one case series; four retrospective reviews; five prospective open-label clinical trials; and one randomized, split-face, comparison trial versus fractional 1550 nm erbium fiber laser involving a cumulative total of 194 subjects [8,9,63,65,66,71,72]. Additionally, there has been one case series of 16 patients studying picosecond laser treatment of hyperpigmented scars; one retrospective review of 24 patients with hypertrophic scars; one retrospective review of nine patients with atrophic surgical scars which was subsequently extended by the same group to include an additional eight subjects with atrophic scars and eight subjects with hypertrophic surgical scars; and one randomized, evaluator-blinded, split-body comparison trial of fractionated picosecond Nd:YAG laser versus 1565 nm fractional non-ablative laser for the treatment of striae alba in 20 subjects [64,[67][68][69][70].…”

Background and Objectives The use of picosecond laser in dermatology was originally focused on optimizing the removal of unwanted tattoos. Subsequent advances in this technology have broadened its clinical indications to include treatment of benign pigmented lesions, photodamage, melasma, and scar revision. In this systematic review, evidence‐based recommendations are developed for the use of picosecond laser in dermatology. Study Design/Materials and Methods A comprehensive search of the English language literature was performed up to and including November 2019. Relevant citations were individually evaluated, synthesized, and categorized based on the Level of Evidence. With the addition of the authors’ combined clinical experience, clinical recommendations were developed. Results After application of inclusion and exclusion criteria, a total of 77 unique studies were evaluated. Treatment of benign pigmented lesions was associated with level I–IV evidence; rejuvenation was associated with level II evidence; melasma was associated with level II evidence; scar revision was associated with level II–III evidence; tattoo removal was associated with level I evidence. Conclusion Picosecond laser is a safe and effective treatment modality for an increasing range of dermatologic indications. Further development of this technology is warranted. Lasers Surg.

Acne scars are the most common sequelae of the severe inflammatory process of acne. They affect almost 95 percent of patients with acne vulgaris, which is prevalent in more than 90 percent of adolescents. 1,2 Scars are characterized by a loss or damage of tissue, vary in morphological characteristics such as shape, size, and depth, 3 and are graded as various types such as rolling, boxcar, and ice pick. Furthermore, they can be erythematous at the early stage, or may get purplish or pigmented as they develop. 4,5 In most patients, acne scars are mixed types and distributed around the face. A standard tool for assessing atrophic scars is the four-grade Goodman and Baron classification. 6 Managing acne scars is a challenge, 7-10 and therapies are divided into nonsurgical and surgical. The former includes anti-acne agents, 11,12 chemical peels, 13 microneedling, 14-17 and ablative 18 and nonablative fractional 19-22 and nonfractional 23 lasers, as well as autologous growth factors. 24-27 The latter include subcision, 28-30 autologous cell regeneration, 31 and autologous adipose-derived stem cells. 32
