“…Because scar tissue remodels over many months, further improvement could occur over a longer follow‐up period. Finally, despite numerous tools available to assess the severity of acne scars, the lack of consensus concerning acne scar evaluation makes it difficult to compare our results with those from other studies .…”

Objectives There have been few studies regarding the use of a picosecond‐domain laser for acne scars in Asians. This prospective study evaluated the efficacy and safety of a high‐energy 1,064 nm Nd:YAG picosecond‐domain laser for ablation and resurfacing of facial acne scars in Asians. Methods Subjects were treated with a 1,064 nm picosecond laser (8 mm spot, 0.7–1.0 J/cm2, 5 Hz) every 4 weeks for three sessions. Two blinded dermatologists evaluated the pre‐ and 3‐month post‐treatment images with a 10‐point improvement scale. Subject pain, global improvement, and satisfaction were also assessed. The Facial Acne Scar Quality of Life (FASQoL) questionnaire was used to evaluate the subjects’ quality of life. Results Twenty subjects aged 18–50 years with Fitzpatrick skin type III–V were enrolled. The median dermatologist‐rated improvement score was 3 out of 10. Subjects were satisfied to very satisfied with global improvement. Subjects’ quality of life significantly improved with a median FASQoL score of 10 after treatment compared with 21 before treatment (P < 0.001). Adverse effects were limited to erythema, pain, and edema without postinflammatory hyperpigmentation. Conclusions The 1,064 nm picosecond‐domain laser with ablative resurfacing parameters is safe and effective for the treatment of acne scars in Asians. Lasers Surg.

Background Both topical and oral probiotics are becoming widely used. There is increasing interest in the cosmetic potential in topical probiotics. Nitrosomonas eutropha is an ammonia‐oxidizing bacteria. Aim The purpose of this study was to assess whether there is any improvement in facial wrinkles with the use of Nitrosomonas eutropha, a topical probiotic. Methods In this prospective study, high‐resolution photographs were obtained in twenty‐nine participants at baseline and after using topical Nitrosomonas eutropha for seven days. Results There was a significant difference in wrinkle depth and severity in the high concentration probiotic group. There was also a statistically significant improvement in pigmentation of the forehead and glabella in the higher concentration group. Conclusions Nitrosomonas eutropha may have aesthetic benefits in terms of reducing the appearance of wrinkles. Larger studies with longer treatment and follow‐up periods are required.

“…A prior study on acne scarring also correlated results of dermatologists’ subjective scores with a 3D photographic modeling system using 3 angled cameras to create a topographic map with computer‐generated quantitative volumetric measurements . This group reported a “statistically significant linear correlation (Spearman rank order correlation 0.76, P < .05) suggesting that facial scar imaging may help quantify postacne scarring.”…”
