The document concludes that a deeper understanding of skin aging and photodamage is needed to create better skin treatments.

Hormones affect skin aging, and treatments targeting hormonal balance may improve skin health.

New treatments for skin damage from UV light using stem cells and their secretions show promise for skin repair without major risks.

Exosomes may improve skin, scars, hair growth, and fat grafts in plastic surgery, but more research is needed.

Targeting the HEDGEHOG-GLI1 pathway could help treat keloids.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

Hormones affect skin aging and fat distribution, and treatments can help, but only minoxidil is proven for female hair loss.
