Infant skin cells may be less capable of repairing UV-induced DNA damage than adult cells.

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.

Genetic defects and UV radiation cause skin damage and aging.

Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.

Researchers found new hair and nail genes, how hair reacts to UV, differences in white and pigmented hair growth, nerve changes in alopecia, treatments for baldness and alopecia, a toenail condition linked to a genetic disorder, and that nail fungus is more common in people with psoriasis.

Cosmetics improve skin and hair health, protect from UV damage, and boost mood and confidence.

Long-term use of seizure medications can disrupt calcium metabolism, but this can be treated with vitamin D or UV light and does not affect seizure control.

BMAL1 controls skin cell growth and UV damage risk, peaking at night.

Caffeic acid protects human scalp cells from UV damage.

Azelaic acid helps protect hair cells from UV damage and encourages hair growth by increasing certain gene expressions and proteins.

Combining hair transplantation with microneedling or laser and UV light may help treat tough vitiligo on hands and feet, with microneedling being affordable and easy to learn.

Damaged hair follicles make mice more prone to skin inflammation and skin cancer after UV exposure.

New wig coating technique makes them more durable, UV resistant, and less static.

Increasing type 17 collagen reduces aging signs in skin cells caused by UV light.

Fat-derived stem cells can help protect and repair skin stem cells from aging caused by UV light.

Sun exposure after laser hair removal can cause skin darkening, which is hard to treat and requires avoiding UV light.

Some moles can disappear naturally, maintenance therapy for Stage 1 mycosis fungoides may not be necessary, allergic skin reactions in children are rising, weekly methotrexate for psoriasis is more effective than daily, long-term finasteride use improves hair growth with few side effects, and petrolatum improves UV therapy for psoriasis.

Melatonin is important for skin health and protection, and can be made by the skin or applied to it.

Researchers created a mouse with the same mutation as humans with trichothiodystrophy, showing similar symptoms and confirming the condition is due to defects in DNA repair and gene activity.

Melatonin may benefit skin health and could be a promising treatment in dermatology.

Caffeine in cosmetics may reduce cellulite, protect skin, and stimulate hair growth, but more research is needed on its use and effects.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

The document concludes that skin biopsies, genetic and environmental factors, and specific treatments are important in managing cutaneous lupus erythematosus.

The cause of Frontal Fibrosing Alopecia is unclear, diagnosis involves clinical evaluation and various treatments exist, but their effectiveness is uncertain.

Vitamin D and its receptor may help prevent skin cancer.
