Background: Hyperpigmentary disorder is one of the commonest skin concerns in dermatology clinics. The availability of noninvasive instruments provided a convenient, objective, and reproducible methodology for the evaluation of pigmentation and skin color. The aim of this study is to compare CSKIN and VISIA in measuring facial hyperpigmentation, as well as to assess the correlation between the instrumental analyzing and clinical evaluation.

Methods: Eighty Chinese patients were enrolled. Images were taken and analyzed by VISIA from Canfield and CSKIN from Yanyun Technology, and the facial hyperpigmentation was graded by three dermatologists.

Results: Feature counts within the facial pigmented areas analyzed by VISIA showed positive correlations with brown pixels (r = 0.331, p < 0.05) and brown percent (r = 0.395, p < 0.0001) measured by CSKIN. The parameters measured by CSKIN and VISIA were significantly correlated with visual scores graded by the dermatologists, with VISIA presenting a moderate correlation (r = 0.509, p < 0.001) and CSKIN a slightly stronger correlation with the visual scores (r = 0.653, p < 0.001).

Conclusion: CSKIN could serve as an alternative in the assessment and follow-up of skin disease featuring with facial hyperpigmentation.

Acne and acne sequelae can have an important impact on patients' quality of life, affecting interpersonal relationships and social functioning. Acne-induced scars (AIS) and acne-induced macular hyperpigmentation (AIH), in particular, are a major concern for patients with acne, as their management is challenging and often unsatisfactory. Retinoids are considered the mainstay of acne treatment because of their action on multiple pathogenetic factors, and there is increasing evidence that they can also improve AIS and AIH.

Purpose Of Review: Arboviral infections caused by Dengue, Zika, and Chikungunya viruses continue to pose a significant global health threat, particularly in endemic regions. This review is timely because of the increasing prevalence of these infections, driven by factors such as urbanization and climate change. Dermatological manifestations of these viruses are crucial for early diagnosis, especially given the overlap in symptoms, which can complicate differential diagnosis.

Little is known about the anti-pigmenting effects of skin-whitening agents on solar lentigos (SLs). To characterize the anti-pigmenting effects of a newly designed derivative ascorbyl glucoside-arginine complex (AGAC) on SLs, lotions with or without 28% AGAC were applied twice daily for 24 weeks in a double-blind half-face study of 27 Japanese females with SLs. The pigmentation scores and skin colors of previously selected SLs on the right and left sides of the faces of the subjects were evaluated using a photo-scale, a color difference meter and a Mexameter.

Background: Exosomes are nanoscale vesicles derived from various cell types and tissues that have many potential applications, generating great interest from researchers. One particularly intriguing application of exosomes is their use as a direct therapeutic for aesthetic indications. Several studies and case reports have explored the impact of exosomes for numerous cosmetic concerns but a consensus on the outcomes of these studies has not been established.

Background: There is continuous demand for safe, effective cosmetic ingredients to treat the signs of aging skin, including fine lines, wrinkles, brown spots, discoloration, laxity, and sagging. While there are a plethora of cosmeceutical peptides, few combine anti-aging and anti-inflammatory benefits with small size.

Methods: Preclinical and clinical studies evaluated the anti-inflammatory properties, anti-aging benefits, and tolerability of acetyl dipeptide-31 amide (AP31), a novel, small, anti-aging micropeptide, to understand its impact as a multifaceted, cosmetic, anti-aging, and anti-inflammaging ingredient.
