Abstract:Recently novel picosecond duration lasers (ps-lasers) have been developed for the treatment of multicolored and recalcitrant tattoos, and safety and efficacy have been reported. We therefore hypothesized that the ps-laser could be an alternative treatment for dermal pigmented lesions and performed a retrospective review to evaluate the efficacy and safety of the ps-laser. A retrospective photographic review of 10 patients with dermal pigmented lesions was performed (ages from 4 months to 52 yr), 6 nevus of Ota… Show more
“…The arising of a new generation of QS lasers, the picosecond lasers, seems to have not significantly modified the prognosis of the treatment of Ota naevus except perhaps by being followed by a shorter downtime and by decreasing the incidence of hypopigmentation . However, other prospective studies are required to confirm these facts. Recommendation The 1064 nm QS lasers are the gold standard treatment of Ota and Ito naevus.…”
Background
Lasers and intense pulsed light sources (IPLS) are proposed for the treatment of many pigmentary disorders. They are sometimes considered as magic tools able to remove any type of lesions. Although being the best option for several hyperpigmented lesions, they can also worsen some conditions and have potential side‐effects.
Objective
The aim of this review was to give evidence‐based recommendations for the use of lasers and IPLS in the treatment of hyperpigmented lesions.
Methods
These recommendations were produced for the European Society of Laser Dermatology by a consensus panel made up of experts in the field of pigment laser surgery. Recommendations on the use of lasers and light treatments were made based on the quality of evidence for efficacy, safety, tolerability, cosmetic outcome, patient satisfaction/preference and, where appropriate, on the experts' opinion.
Results
Lasers and IPLS are very effective for treating many hyperpigmented lesions such as lentigos, dermal hypermelanocytosis or heavy metal depositions. In the other hand, they have to be considered with great caution for other disorders, such as café au lait macules, melasma or postinflammatory hyperpigmentation. After making the correct diagnosis, if lasers or IPLS are indicated, the optimal wavelengths and parameters will be chosen taking into account the skin phototype, origin and depth of the target pigments.
Conclusion
Although potentially very effective, lasers and IPLS cannot be proposed for all types of hyperpigmented lesions. In all cases, precise recognition of the disorder is mandatory for choosing between these devices and other therapeutic approaches.

“…On the other hand, picosecond lasers were used initially to remove tattoo inks [15,16], then for various kinds of benign pigmentary problems [17][18][19][20], and additionally, these are used for acne scars and wrinkles [21][22][23]. Relatively higher efficacy and lower incidence of adverse effects have been reported with these lasers.…”
“…Recently, novel picosecond duration lasers (ps-lasers) have been developed for the treatment of unwanted tattoos [23][24][25][26][27]. The picosecond pulse duration is 10 times shorter than the traditional q-switched nanosecond devices.…”
Alopecia areata (AA) is an autoimmune disorder causing nonscarring hair loss. Alopecia totalis (AT), the severe form of AA, is usually refractory to many first-line treatments including topical and intralesional corticosteroids and topical immunotherapy. Systemic corticosteroids, ultraviolet light phototherapy, and immunosuppressants may be effective but can cause side effects and high recurrence rates after discontinuing treatment. Janus kinase inhibitors and numerous types of lasers, such as 308 nm excimer laser or light, low-level laser therapy, and fractional lasers have been explored for alternative treatment of AA over the past few years with beneficial effects. Herein, we presented a case of AT treated with the novel 1064 nm picosecond Nd:YAG laser (ps-Nd:YAG) (Cutera, Brisbane, CA, USA) under a split-scalp study. A 25-year-old woman presenting with AT for two years was treated with topical and intralesional steroid and the 1064 nm Nd-YAG picosecond laser on the right half of the scalp. The laser treatment interval was once a month. The left half of the scalp was treated with topical and intralesional steroids alone. After treatment for six times, the right half of the scalp had greater improvement than the left half of the scalp. 1064 nm picosecond Nd:YAG laser therapy may be an effective alternative adjuvant treatment for AT.
