“…Our study's findings suggest a significant efficacy of lasers in lentigo and other superficial lesions and lower phototypes. The patients reported outstanding satisfaction levels, and a very low number of treatment sessions was necessary, confirming the picosecond pulsed laser as very effective as already reported by other studies in the medical literature [18,[27][28][29].…”

(1) Benign melanoses are a frequent issue in aesthetic dermatology. Solar lentigo, ephelides, café au lait spots, and other melanoses represent a cosmetic issue for a growing number of subjects. The Q-switched 1064/532-nanometer (nm) laser may be considered the gold standard for management of these aesthetic issues. A new generation of Q-switched lasers, capable of concentrating the energy pulse in the spectrum of hundreds of picoseconds, is emerging, promising better results than previous ones. In this paper, we report the use of a Q-switched laser with a picosecond pulse to manage hypermelanoses. (2) Methods: 36 patients seeking melanosis removal were retrospectively enrolled at Magna Graecia University of Catanzaro. Treatment parameters, although variable, were the following: 1064 nm with a pulse duration of 450 picoseconds (ps) for dermic lesions and 532 nm with 370 ps for epidermal lesions. Up to four treatments, with a minimum interval between laser treatments of 30 days, were performed. After the last session, patients’ satisfaction was assessed at a three-month follow up with a Visual Analogue Scale (VAS). Two blinded dermatologists measured the aesthetic outcome using a five-point scale comparing pictures before laser sessions and during follow-up. (3) Results: 36 patients were enrolled; 23 were females (63.9%) and 13 males (36.1%). The mean reported age was 49.2 ± 18.9 years. All participants were assessed with a complete/almost complete melanosis removal at the dermatological evaluation, with a mean VAS score of 9.39 ± 0.90. (4) Conclusions: The Q-switched 1064/532 nm laser may be considered the main weapon in treating benign hypermelanosis. The picosecond pulse seems to guarantee better results than other devices. However, a clinical trial comparing Q-switched nanosecond pulse with picosecond pulse is necessary to confirm this study’s findings.

“…In the case of melanin, although there were not many articles on the subject, some articles used petrolatum as a control for other cream studies. In some, control Vaseline showed a melanin increase, as in this study [ 19 ]. This could be explained by the color of the product.…”

Excipients are used as vehicles for topical treatments; however, there are not many studies that evaluate the impact of different excipients themselves. The aim of this research is to assess skin homeostasis changes in healthy individuals after using water/oil (W/O), oil/water (O/W), Beeler base, foam and Vaseline excipients. A within-person randomized trial was conducted that included healthy individuals without previous skin diseases. Skin barrier function parameters, including stratum corneum hydration (SCH), transepidermal water loss (TEWL), pH, temperature, erythema, melanin and elasticity (R0, R2, R5 and R7), were measured on the volar forearm before and after using each excipient. Sixty participants were included in the study, with a mean age of 32 years. After applying w/o excipient erythema decreased by 25 AU, (p < 0.001) and elasticity increased by 6%. After using the o/w excipient, erythema decreased by 39.36 AU (p < 0.001) and SCH increased by 6.85 AU (p = 0.009). When applying the Beeler excipient, erythema decreased by 41.23 AU (p < 0.001) and SCH increased by 15.92 AU (p < 0.001). Foam and Vaseline decreased TEWL and erythema. Excipients have a different impact on skin barrier function. Knowing the effect of excipients on the skin could help to develop new topical treatments and help specialists to choose the best excipient according to the pathology.

“…Side effects may include pain, erythema, edema, pinpoint bleeding, crusting, blistering, scarring, and postinflammatory hyperpigmentation. Our study’s results suggest increased effectiveness of lasers in the epidermal lesions, with better results when treating the extremities or the trunk, and lighter phototypes [ 24 , 25 , 26 ]. Digital skin analysis devices, especially when performing melanin biometric measurements, may be very useful in better scoring the improvement of the patient.…”

(1) Benign hyperpigmentations are a common problem in cosmetic dermatology. Melasma, solar lentigo, and other acquired hyperpigmentations represent an aesthetic issue for an increasing number of patients. The gold standard in managing this condition is currently 1064/532 nanometers (nm) Q-Switched lasers. This study reports our experience on the use of a Q-switched laser with a nanosecond pulse to treat these conditions. (2) Methods: A total of 96 patients asking for benign hyperpigmentation removal were consecutively enrolled at the Magna Graecia University of Catanzaro and Tor Vergata University of Rome. Treating parameters were the following: 1064 nm with a pulse duration of 6 nanoseconds (ns) for dermic lesions and 532 nm with 6 ns for epidermal ones. Up to five treatments with a minimum interval between laser treatments of thirty days were performed. A follow-up visit three months after the last session assessed patient satisfaction with a Visual Analogue Scale (VAS). Two blinded dermatologists assessed the cosmetic result using a five-point scale comparing pictures before treatment and at follow-up. (3) Results: 96 patients were included; 47 participants were women (49.0%) and 49 men (51.0%). The mean reported age was 50.0 ± 17.3 years. All patients reached a good to complete hyperpigmentation removal at the dermatological evaluation with a mean VAS score of 8.91 ± 1.07. (4) Conclusions: Q Switched 1064/532 nm laser may be considered the gold standard treatment for benign hyperpigmentations. Our results confirm the literature findings on the effectiveness of these devices.
