In this study, both excimer light and low level light therapy were found to be safe and effective for treating alopecia areata, with excimer light showing better and more sustained improvement.

In this study, researchers found that Asian hair contains more integral lipids than European or African hair, which may protect it better from UV-induced damage.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.

This study found that lysine carboxymethyl cysteinate helps protect the epidermis from UVB-induced damage by activating autophagy and restoring cornification processes in a skin model.

This review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

This review discusses the potential of ultraviolet (UV) radiation technologies in wound care, highlighting their antimicrobial properties and risks of DNA damage, but reports no new clinical findings.

This study found that UV exposure in human skin induces IL-10 production by macrophages, while Langerhans cells are depleted and their IL-12 production is downregulated.

An 8-year-old girl with vitiligo developed extra hair growth on her knee after using tacrolimus ointment.

This study found that bioengineered skin substitutes developed for 21 or 28 days effectively mimic native skin's ability to absorb UV radiation, suggesting suitability for treating severe skin defects.

This study noted that combining oral acitretin with narrowband ultraviolet B therapy may reduce treatment time and dosages for psoriasis, potentially lowering the long-term skin cancer risk.

This review discusses the effects of calorie restriction on skin aging, highlighting its potential to benefit skin health by reducing age-related and photo-induced changes, although the impact of certain diets remains unexplored.

This article discusses the multifactorial nature of acne, including its association with follicular hyperkeratosis, sebaceous lipids, Propionibacterium acnes, and perifollicular inflammation, but reports no new clinical findings.

This chapter discusses various substances and therapies for dermatological applications, including heliotherapy, UVB, khellin, and others, but reports no new research findings.

In this study, tempeh oil rich in PUFAs, particularly from black soybean, significantly down-regulated MMP-9 gene expression in UVB-irradiated mice skin, indicating potential for use in preventing skin photoaging.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

This study found that IL-9 influences the behavior of human primary keratinocytes by promoting motility while reducing invasion potential through a novel mechanism independent of matrix-metalloproteinases.

The researchers reported that in nonmelanoma skin cancers, the expression of osteopontin splice variants is significantly higher compared to normal skin, with OPN-a elevated in basal cell carcinoma more than OPN-c.

Some treatments can improve skin's defense against damage, but overuse may cause other skin problems.

This review discusses the chemical effects of UV radiation on hair, hair photoaging, and photoprotective measures, and calls for more focused research in hair photoprotection as a field.

In this study, the use of wellness apparel emitting red and NIR light was associated with improved disease severity in patients with mild elbow psoriasis, PMLE, and limited AA, though the small sample size and continued use of other treatments were noted as limitations.

This review discusses how physical appearance, including skin, facial features, and physique, is linked to aging and health risks, but reports no new experimental results.

This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

This study found that both topical calcipotriol and narrow band ultraviolet B phototherapy improved hair regrowth and vitamin D3 levels in alopecia areata patients.

This article reviews practical approaches for managing dermatologic conditions in patients with skin of color and reports no new clinical findings.

This study found that combining excimer light at 308 nm with tacrolimus 0.1% was more effective in treating alopecia areata of the scalp compared to excimer light alone, as indicated by a greater reduction in the SALT score and better improvement in Treg function.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.

This review discusses the challenges in selecting optical parameters for photobiomodulation studies on hair regrowth and wound healing, reporting no new clinical results and recommending more rigorous, standardized research approaches.

The conference concluded that understanding hair and nail disorders is important, iron deficiency may be linked to hair loss, and while some treatments for skin conditions are effective, they may have risks and high costs.
