Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

Facial plastic surgery has evolved to focus on less invasive techniques and innovative technologies for cosmetic and reconstructive procedures.

Hair follicle stem cells can help repair nerve and spinal cord injuries.

Touch sensitivity in mouse skin decreases during hair growth due to changes in touch receptors.

Hair follicle shape determines hair type: curly, straight, or in-between.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

Lidocaine-loaded microparticles effectively relieve pain and fight bacteria in wounds.

Scientists have made progress in growing mini-organs and regenerating parts of the skin, with plans to treat hair loss in a future trial.

Platelet-based therapies using a patient's own blood show promise for skin and hair regeneration but require more research for confirmation.

The method increases stem-like cells for better skin regeneration.

The study suggests computer-assisted analysis of scalp biopsies could improve hair loss diagnosis but needs more validation.

Photoacoustic imaging can accurately assess hair follicle density and orientation for hair transplant planning.

New materials that better mimic natural skin structure could improve healing, especially for chronic wounds.

Deoxycholic acid effectively reduces double chin fat with temporary side effects and high patient satisfaction.

New topical treatment using spherical nucleic acids shows promise in reducing psoriasis inflammation.

The new wound dressing material speeds up healing, fights infection, and outperforms traditional dressings.

New synthetic polymers help improve skin wound healing and can be enhanced by adding natural materials and medicines.

Cirsium japonicum flower extract increases melanin production and could help treat depigmentation conditions.

HAP stem cells can repair nerves, grow hair follicle nerves, and become heart muscle cells, making them useful for regenerative medicine.

Certain cells around hair follicles help improve skin regeneration for potential use in skin grafts.

Nanofiber scaffolds help wounds heal by delivering drugs directly to the injury site.

The document concludes that more research is needed on making and understanding biomaterial scaffolds for wound healing.

The research showed that CRISPR/Cas9 can fix mutations causing a skin disease in stem cells, which then improved skin grafts in mice, but more work on safety and efficiency is needed.

A single medium, PRIME AIRLIFT, supports better human hair follicle formation in grafts.

Mesenchymal stem cell proteins in a special gel improved healing of severe burns.

The PRECISE scale helps estimate how many grafts are needed for hair transplant based on the severity of hair loss.

Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

Skin organoids with NCSTN mutation show changes in hair follicle development and higher inflammation, key features of Hidradenitis Suppurativa.

Scientists improved how to make skin-like structures from stem cells using special gels and a device that controls growth signals, leading to better hair and skin features.

The study concludes that as skin matures from infancy to childhood, there are major changes in cell differentiation, stemness, and growth, leading to a stronger skin barrier in older children.
