“…The use of MLA may contribute to elimination of the cellular component of ABNOM, which previously caused pigments to be resistant and to respond inconsistently to treatment. Similar results were also concluded in a previous study [21] in which PS laser treatment yielded better clinical outcomes and fewer adverse effects than QS laser treatment.…”

Picosecond (PS) laser is a novel dermatological laser technology that is useful in treating various cutaneous benign pigmentary disorders (BPDs), including freckles, solar lentigines, melasma, Hori macule, nevus of Ota, post-inflammatory hyperpigmentation, and tattoo. Treating Asian BPDs can be troublesome as Asian skin is typically associated with a high incidence of laser complications, such as burns, hyperpigmentation/hypopigmentation, and textural changes, which can result in various cosmetic and even psychosocial problems. This study aimed to describe the PS laser treatment for common Asian BPDs compared with traditional laser treatments. Peer-reviewed articles published from 1965 to 2018 were identified from PubMed and Google Scholar, and qualitatively reviewed with respect to the treatment of Asian BPDs. PS lasers achieved greater effectiveness and potentially fewer complications in the treatment of Asian BPDs through breakthrough mechanisms including photomechanical effects and laser-induced optical breakdown. PS laser is especially suitable and effective for treating various BPDs in Asian skin.

“…PIH is reported after laser therapy in Hori's nevus following high fluence QSNYL (Kunachak & Leelaudomlipi, ; Lee et al, ; Suh et al, ), low fluence QSNYL (Polnikorn et al, ), combination of QSNYL 532 nm and QSNYL 1064 nm (Ee et al, ), QSAL(Lam et al, ; Wang & Chen, ; Yu et al, ), QSRL (Kunachak et al, ) and after dermabrasion (Kunachak et al, ). The lesions were more common after high fluence QSNYL therapy.…”

“…Both QSAL 3 mm + HF and 4 mm + LF were found to be comparable in efficacy and safety (Wang & Chen, ). When QSAL is compared to PSAL, PSAL was found to be more efficacious with low pain sensation and lower PIH rates compared to QSAL (Yu et al, ).…”

“…While comparing PSAL and ER:YAG + ND:YAG combination, in PSAL treated patients, excellent improvement was seen in 76.7% cases and rate of transient PIH was 27.77% (lasted for mean of 1.32 ± 0.73 months) (Yu et al, ). On the other hand in case of ER:YAG + ND:YAG combination, excellent improvement was seen in 100% patients and there was not even a single case of dyschromia.…”

Hori's nevus is a pigmentation disorder reported mainly in middle-aged Asian women.There is no systematic review addressing its pharmacotherapy. The population for our systematic review was patients with a clinical/histological diagnosis of Hori's nevus (both sex, any age group). We screened five literature databases using relevant keywords. All RCTs, observational studies and case series mentioning at least one intervention and outcome of that intervention were included. Nineteen studies were included in the final systematic review from total 680 identified nonduplicate records. Different forms of laser (alexandrite laser [QSAL and PSAL], Nd:YAG laser [QSNYL high fluence, low fluence, 532 followed by 1064 nm], Er: YAG and Nd:YAG combination, ruby laser [QSRL], CO 2 laser followed by QSRL) and dermabrasion were found to be useful in treatment of Hori' nevus. Among alexandrite lasers, PSAL is more efficacious and safe than QSAL. In case of high fluence QSNYL, hyperpigmentation rate is quite high while low fluence QSNYL requires more number of treatment sessions. The combined 1064 nm + 532 nm protocol is better in terms of efficacy and safety. Er:YAG + Nd:YAG combination have similar efficacy and added advantage of synergistic action and no adverse event.

A Systematic Review of Picosecond Laser in Dermatology: Evidence and Recommendations

et al. 2020

View full text Add to dashboard Cite

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.
