The study concluded that the most common skin changes in elderly people are wrinkles and dry skin, with various infections, benign tumors, and changes in nails and hair also being significant.

Iris germanica rhizome-derived exosomes help protect skin cells from oxidative stress and aging.

Up to half of people experience itchy scalp, often due to skin conditions like seborrheic dermatitis or psoriasis, and treatments vary based on the specific cause.

Anigozanthos Flavidus flower extract helps regenerate skin and reduce wrinkles.

Treatments that reduce oxidative stress and fix mitochondrial problems may help heal chronic wounds.
