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.

This study found that apocynin restored COL17A1 expression in human keratinocytes and reduced UVB-induced cellular senescence, DNA damage, and cell cycle arrest.

Excimer laser therapy can be an alternative for treating superficial morphea when topical steroids don't work.

This study observed that applying polyamines to the skin of hairless mice stimulates thymidine incorporation, suggesting polyamines may play a role in DNA synthesis control in the epidermis.

This study found that deleting the transcription factor Twist1 in keratinocytes significantly reduced UVB-induced skin carcinogenesis in mice, suggesting a potential target for preventing cutaneous squamous cell carcinoma.

In this study, overexpression of ornithine decarboxylase accelerated basal cell carcinoma in Ptch1+/– mice under UVB exposure, while its inhibition reduced tumor induction, suggesting potential chemoprevention strategies in humans.

This review discusses plant extracts for dermatological use, highlighting evidence that some can reduce edema in chronic venous insufficiency or help treat actinic keratoses, but it reports no new clinical results.

Kesh Kanti Expert Oil promotes hair growth and protects hair health.

This study found that inhibiting the enzyme ornithine decarboxylase (ODC) prevented UVB-induced basal cell carcinomas in a mouse model, suggesting ODC is a potential target for chemoprevention strategies.

This study found that PKCα activation in transgenic mice induces keratinocyte apoptosis and mediates neutrophilic skin inflammation via different pathways, suggesting potential mechanisms for cutaneous inflammatory diseases.

This review discusses the role of vitamin D metabolism in skin immunity and wound healing but does not present new results, highlighting the need for further research into its therapeutic applications.

This study observed that PCE-DP may improve skin pigmentation by increasing epidermal turnover and inhibiting melanin uptake and inflammation in human epidermal keratinocytes.

UV radiation may cause DNA changes in skin, certain UVB therapy helps psoriasis, a new gene mutation is linked to mild piebaldism, different immune cells affect psoriasis, a drug promotes hair growth, and some cancer drugs could treat skin barrier issues.

This study reported that introducing the TERT and Bmi1 genes into mouse dermal papilla cells resulted in immortal cells capable of inducing new hair follicles in vivo, and human immortal DPCs were also developed.

This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

In this in vitro study, pretreatment with Dead Sea water and saline magnetized water reduced UVB-induced DNA damage and inflammation markers in human keratinocyte cells, primarily through autophagy activation, suggesting potential use in topical products to prevent skin damage from UV exposure.

This study found that hairless mice with homozygous mutations developed significantly more aggressive basal cell carcinomas and a heightened inflammatory response to UVB exposure compared to their haired littermates.

The researchers reported that cancer incidences are rising over time in developed countries, with potential carcinogenic drivers including advancing age, estrogen, decreasing vitamin D3, and Human Papillomavirus.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.

This study found that deleting the Twist1 gene in skin keratinocytes significantly reduced UVB-induced skin cancer and hyperproliferation in mice and suggested Twist1 as a target for skin cancer prevention.

This study found that UV-B exposure significantly increased the expression of inflammatory cytokines IL-1β and IL-8 in cultured sebocytes.

This study found that human hair follicles serve as a crucial reservoir for Langerhans cells, which repopulate the epidermis depleted by ultraviolet B exposure.

In this study, 15d-PGJ2 administered in a topical cream inhibited oxidative and inflammatory skin changes caused by UVB radiation in hairless mice, suggesting it as a promising treatment approach.

In this study, treatment with cell-derived nanovesicles from hair follicle mesenchymal stem cells improved photoaging signs in UVB-exposed mice and human dermal fibroblasts by reducing oxidative stress, enhancing cell proliferation, and promoting extracellular matrix production.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.

In this study, orally administered Centella asiatica extract, standardized for asiaticoside content, significantly improved skin barrier function, elasticity, and reduced signs of UVB-induced photoaging in hairless mice, highlighting its potential as a nutricosmetic for skin health.

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.
