The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Tiny pollution particles called PM2.5 can harm skin cells by causing stress, damage to cell parts, and cell death.

Certain spices may help prevent and treat skin cancer, but more human trials are needed.

Ginsenoside Rg1 protects mouse skin from UVB damage and helps control inflammation.

Women in Australia report different signs of facial aging compared to women in the US, UK, and Canada; men with Lichen planopilaris often have hormonal abnormalities and thyroid disease.

New nanocomposites with copper show promise for healing burn wounds and regenerating skin.

Platelet-rich plasma (PRP) speeds up skin wound healing and has potential in medical and cosmetic uses.

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

Men with androgenetic alopecia have oilier and less hydrated scalps, especially in sensitive areas.

Probiotic bacteria improved skin and hair health in aged mice.

Hair disorders are caused by a complex mix of biology, genetics, hormones, and environmental factors, affecting hair growth and leading to conditions like alopecia.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

Hair loss in Rhesus macaques may be caused by a skin allergy-related condition.

Adult acne severity is influenced by stress, skin sensitivity, makeup, stopping oral contraceptives, and requires female-specific treatment guidelines.

Backhousia citriodora leaf extract effectively reduces oily skin across different ethnic groups.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

FFA's causes may include environmental triggers and genetic factors.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

Older adults have a wide range of skin conditions, with dry skin being very common and many also experiencing skin growths, itching, and infections.

Hair analysis can show nutritional status and environmental exposure, with phosphorus being very stable in hair and differences found based on gender and conditions like depression and autism.

HIF-1A may aid hair growth, Backhousia citriodora improves skin, autologous cells stabilize hair loss, infrared thermography assesses alopecia, and a new treatment preserves hair.

The document concludes that managing skin conditions during pregnancy is important and requires specialized care.

Injections of special skin cells showed potential in treating hair loss, with some participants experiencing increased hair density.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Human hair contains diverse proteins, including keratins and histones, which could help assess hair health and aging.

Genetic variations affecting skin structure play a key role in severe acne.

The document suggests that blocking sweat glands with antiperspirants might allow skin-generated hormones to be absorbed, possibly increasing breast and prostate cancer risk.
