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

The LED light therapy mask improved skin elasticity and reduced signs of aging in a test and in women aged 40-60.

Older mice have stiffer skin with less elasticity due to changes in collagen and skin structure, affecting aging and hair loss.

Microneedling improves skin and hair conditions by enhancing treatment absorption and stimulating growth factors.

Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.

Non-invasive methods show promise for diagnosing skin diseases like psoriasis and lupus but need more research for regular use.

Hyaluronic acid filler injections are a favored non-surgical method to improve facial aging signs due to their convenience, effectiveness, and durability.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.
