The Brazilian Society of Dermatology agrees that oral isotretinoin is effective for acne and other skin conditions, and it's safe when monitored, but more research is needed on dosing and duration.

Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.

The study found that a specific signaling pathway helps skin wounds heal faster but may lead to larger scars.

Wound covers with α-13'-COOH from vitamin E can improve and speed up wound healing.

Skin cell-derived vesicles can help heal skin injuries effectively.

The new hydrogel is good for wound dressing because it absorbs water quickly, has high porosity, can release drugs, fights bacteria, and helps wounds heal with less scarring.

Different cell types work together to repair skin, and targeting them may improve healing and reduce scarring.

Body-hair transplant successfully improved scarred areas and frontal hair density without visible chest scarring.

The document concludes that treatments for cicatricial alopecia are not well-supported by evidence, but hair transplantation shows more predictable and satisfactory results.

Using developmental signaling pathways could improve adult wound healing by mimicking scarless embryonic healing.

Keratin hydrogel from human hair helps rats recover better from spinal cord injuries.

The symposium highlighted the importance of understanding disease mechanisms for targeted dermatology treatments.

Disrupting YAP signaling in skin cells leads to scar-free healing directed by specific cell signals.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Scarless healing is complex and influenced by genetics and environment, while better understanding could improve scar treatment.

Topical tretinoin may increase beard hair density.

Testosterone may worsen hair loss by affecting hair growth signals, while different prostaglandins can either hinder or promote hair growth.

A new hydrogel with micronized amnion helps achieve better, scar-free skin healing.

Activating TRPA1 reduces scarring and promotes tissue regeneration.

Bacteria can help skin regenerate through a process called IL-1β signaling.

Researchers found a specific immune receptor in patients that causes severe skin reactions to a drug.

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

The drug Albendazole, used for treating parasites, can cause sudden hair loss.

Fat cells help recruit healing cells and build skin structure during wound healing.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Blocking COX, especially COX-2, in the skin can reduce inflammation and pain and may help prevent skin cancer.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

miR-218-5p helps skin and hair growth by targeting SFRP2 and activating a specific signaling pathway.

New hair transplant methods offer more natural results and better graft survival, with ongoing research to increase donor hair options.

LED light therapy is effective for skin and hair treatments but requires careful use to minimize risks.
