Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.

Scientists developed tools to observe hair regeneration in real time and assess skin health, using glowing mice and light-controlled genes.

Ultrasound is a useful, non-invasive tool in dermatology for diagnosing skin conditions and guiding treatments, but it has some limitations.

The study introduced a new imaging technology to track skin healing and bone marrow cell activity over time.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.

Thicker hair grows faster; hair loss patients have slower growth.

Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.

Multiphoton microscopy effectively images rabbit skin structures in detail without staining and shows differences from human skin.

NIR-II imaging effectively tracked stem cells that helped repair facial nerve defects in rats.

The keratin network in mouse skin changes during cornification and affects the skin's protective barrier.

Topical glucocorticoids thin the skin and change collagen structure.

A girl initially thought to have a psychiatric disorder was later found to have a lupus-related condition, which improved with proper treatment.

The technique effectively shows how human skin and hair cells form into ball-like structures.

Women with PCOS often have hair loss, which is linked to acne or excess body hair but not to worse hormone or metabolic issues.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

More research is needed to understand hair and scalp disorders in people with skin of color.

Higher light doses cause more damage to hair follicles, predicting better hair removal results.

A young woman with late-stage Vogt-Koyanagi-Harada disease was successfully treated at a hospital.

New imaging tools help doctors better examine hair and scalp health without surgery.

Men with baldness, ear creases, and hairy ears have a higher risk of heart disease.

Imaging helps detect adrenal gland issues and monitor treatment in congenital adrenal hyperplasia, and can identify tumors affecting fertility.

New imaging techniques can assess and track changes in mouse acne without harm, aiding treatment choices.

Genetic risk for PCOS can affect children's growth, metabolism, and development from early life into adulthood.

The hair cuticle is made of tough proteins that protect the hair, but more research is needed to fully understand its structure.

The document concludes that specific dermoscopic features can help diagnose different facial red skin conditions.
