“…Akerman et al 18 have reported an overall moderate improvement in scar appearance and a statistically significant decrease in scar severity in post‐surgical scars using a similar approach with the nanosecond 1064 nm wavelength in a fractional delivery mode, but with lower energies per pixel. Histological changes (multicellular and wavy epidermis, dense collagen fibers, and collagen regeneration in the dermis) were also observed in a study by Urdiales‐Galvez et al 21 where a fractional approach for the improvement of acne scars was used also with picosecond lasers (around 10 times shorter pulses) of the same wavelength, showing good results.…”

“…In recent years, new studies have shown that the fractional Q‐switched (nanosecond and picosecond) laser can be highly effective in the treatment of acne scars and other indications with minimal side effects. However, most of these studies have used lower, non‐ablative fluences 15–20 . The aim of our study was to assess the efficacy and safety of Nd:YAG laser treatments using a higher, ablative fluence that in our experience gives better results with fewer sessions when compared to lower, non‐ablative fluence treatments.…”

Acne vulgaris is one of the most common skin diseases; it will affect one out of two people in their lifetimes and about 80% of people aged between 11 and 30 years. [1][2][3] Acne scarring, a common complication, develops to some degree in the majority of acne sufferers. 4 Scars are divided into three general categories: ice-pick scars, rolling scars, and boxcar scars 5 and are a result of excessive inflammation, acne severity, physical manipulation of the skin, and a delay in seeking adequate treatment. 3 It affects people both physically and emotionally worldwide, regardless of sex, age, and ethnicity. 2,6 There is also a negative societal perception of acne scars. 7 Unfortunately, many cases of acne remain untreated or are treated sub-optimally, and patients that later develop acne scarring often need acne scarring treatment. None of the currently available treatments achieve a complete resolution of scars, and thus, prevention of scarring by early and aggressive acne treatment is the best option. 8 There are many different treatment modalities for acne scarring, such as chemical peeling, retinoids, dermabrasion, microneedling, subcision, surgical excision, dermal fillers, platelet-rich plasma (PRP), and different energy-based devices. Evidently, a combination of various treatment modalities gives better results than monotherapy. 8,9 Energy-based devices, such as intense pulsed light (IPL), radiofrequency, and lasers, have gained popularity as part of the scar treatment arsenal in recent years. The ablative 2940 nm Er:YAG and 10 600 nm CO 2 lasers have been used in treating various types of scars. However, due to adverse effects such as edema, erythema, dyspigmentation,

“…Both our own personal experience and the available literature convince us that non‐ablative lasers, both fractional and non‐fractional, are useful in treating various types of scars 3 including post acne scars 4 . However, one important issue has to be address before initiating treatment, which is setting realistic patients expectations regarding outcome.…”

“…In the past decade, the safety and efficacy of a Q-Switched domain, 1064 nm neodymiumdoped yttrium aluminum garnet (Nd: YAG) laser have been widely demonstrated in many different conditions like melasma, tattoo removal, hair removal, and skin rejuvenation [6][7][8][9][10]. A growing interest in treating scars with fractional Nd: YAG laser is present [11].…”

Fractional Q-Switched 1064 nm Laser for Treatment of Atrophic Scars in Asian Skin

et al. 2022

View full text Add to dashboard Cite

Background and Objectives: Asian patients with Fitzpatrick skin type III-IV are a less studied subtype of patients in the medical literature. Q-Switched, 1064 nm neodymium-doped yttrium aluminum garnet (Nd: YAG) laser with a fractionated beam profile (QSF) is a new modality that was reported to be effective in the treatment of scars. This study aims to evaluate the efficacy and safety of QSF Nd: YAG laser in treating scars in Asian patients. Materials and Methods: A total of 29 Subjects were treated with 1064 nm QSF laser. Each patients had three treatments with a fractionated microlens array handpiece every 8 weeks). Efficacy of treatment was evaluated using the Goodman and Baron’s quantitative grading scale before and 3 months after the last treatment. Results: All 29 patients treated had significant improvement of acne scars according to Goodman and Baron’s Quantitative Global Acne Scarring Grading System. No side effect has been observed except some minor erythematous reactions in three patients. Conclusions: Our results confirm that the 1064 nm QSF Nd: YAG laser is a safe and effective technique for treating scars in Asians.
