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

Estrogen therapy can reduce skin aging but has cancer risks.

Transplant success has improved with better immunosuppressive drugs and donor matching.

Estrogen replacement can improve skin health in menopausal women but doesn't reverse sun damage or prevent hair loss.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

The conclusion is that PCOS is caused by ovarian sensitivity to hormones and disrupted hormone control, possibly due to ovarian factors, and more research is needed.

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.

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

Surgeons must understand the full care process for gender confirmation surgery to help transgender individuals effectively.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

Male pattern baldness involves hormones and cell signals affecting hair growth.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.

The conclusion is that the increasing use of drugs for lifestyle reasons is a complex issue influenced by corporate profit, consumer behavior, and the medicalization of everyday life, with potential negative effects on personal well-being.

Adult female acne treatment should be personalized, considering individual preferences and pregnancy, using various topical and oral medications while managing side effects and resistance.

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

People with PCOS, especially if obese, often have NAFLD, linked to obesity, insulin resistance, and high androgen levels.

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.

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

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

High-dose dutasteride reduces PMDD symptoms by stabilizing neurosteroid levels.

Nerves and chemicals in the body can affect hair growth and loss.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

Targeted cancer therapies often cause skin reactions, so dermatologists must manage these effects.

Minoxidil helps hair growth by activating the β-catenin pathway.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

BMP2 and BMP7 have opposite roles in feather formation.
