HtrA2 activity is crucial for normal hair growth by regulating fat cell development.

The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.

An elderly woman with cancer improved after treatment for a rare skin condition with coiled hairs.

The transfollicular route shows promise for noninvasive, targeted drug delivery but needs more research.

Skin can be cooled quickly and safely during laser treatments to protect it without affecting deeper layers.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.

Printing human stem cells and a special matrix during surgery can help grow new skin and hair-like structures in rats.

The study found that giant pandas have more melanin in black hair follicles than white, with gene expression differences that could affect hair color and skin health.

Skin fat cells help with skin balance, hair growth, and healing wounds.

Nanoparticle-based drug delivery to hair follicles is more effective when tested under conditions that match skin behavior.

Polymeric nanoparticles show promise for treating skin diseases.

Injecting alpha-melanocyte-stimulating hormone in mice improved skin healing and reduced scarring.

New skin disease treatments using TDDS are improving but face challenges like side effects and high costs.

WWOX deficiency in mice causes skin and fat tissue problems due to disrupted cell survival signals.

Human skin xenografting could improve our understanding of skin development, renewal, and healing.

The PP2A-B55α protein is essential for brain and skin development in embryos.

Mitochondrial therapy and platelet-rich plasma therapy both stimulated hair regrowth in aging mice, with mitochondrial therapy showing similar effectiveness to plasma therapy.

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.

Microparticles help caffeic acid stay longer in hair follicles for better treatment of folliculitis.

Human skin cells produce proenkephalin, which changes with environmental factors and skin diseases.

Advanced nanocarrier and microneedle drug delivery methods are more effective, safer, and less invasive for treating skin diseases.

Heat and chemicals improve finasteride delivery to scalp and hair follicles, potentially enhancing treatment for hair loss.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Hyaluronic acid and versican are important for skin healing and hair growth and might help in regenerative medicine.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Liposomal systems show promise for delivering drugs through the skin but face challenges like high costs and stability issues.

Liposomes could improve how skin care products work but are costly and not very stable.

The flutamide-loaded hydrogel is a promising, skin-friendly treatment for acne and hair loss, potentially requiring less frequent application.

Spin traps like PBN could protect skin from pollution and sunlight in cosmetics but need more research for safe use.
