“The participants engaged in a twice-weekly supervised exercise program involving either aerobic or resistance training for 16 weeks. The researchers evaluated the participants' skin properties, body composition, and physical capacity before and after the intervention.”

“Vitamin C supports collagen production and stress defenses, yet few studies directly measure how diet influences vitamin C inside living skin. A new study tackled this gap by tracking how increasing vitamin C intake from whole foods changes vitamin C levels inside different layers of human skin.”

“The women had similar baseline measurements of skin elasticity, skin moisture, transepidermal water loss, and skin roughness. Compared to the placebo, both hydrolyzed collagen doses increased skin elasticity by an average of 7 percent after four and eight weeks of intake.”

“Tissues with higher numbers of mitochondria (such as muscle, brain, heart, and nerves) tended to respond better to lower light doses. In contrast, tissues with lower mitochondrial activity (skin, tendon, and cartilage) responded better to higher light doses.”

“The skin is an important biological barrier that plays critical roles in the body's innate immune response. Skin allergies, which typically appear early in life and can impair barrier function, have become more common in recent decades.”

“About 12,000 of them took oral nicotinamide (500 mg twice daily for at least 30 days), and were matched with over 21,000 nonusers. Researchers tracked the time until the next treated skin cancer, including two types: basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC).”

“A recent study found that supplemental collagen combined with antioxidants substantially improved the appearance and health of skin and hair in adult women, reducing wrinkle depth by 48 percent. The study involved 40 healthy adult women between the ages of 38 and 50.”

“An antioxidant compound that is used in dye and has shown promise in treating Alzheimer's disease has now shown potential in reversing skin aging in human skin. The compound is called methylene blue and is a very potent antioxidant.”

“Older age can also have a profound effect on the skin's ability to produce vitamin D3. The skin of a person in their seventies produces roughly 25 percent of the vitamin D3 produced by a person in their twenties.”

“These findings point to a structural, rather than immediate, mode of action. Longer-term outcomes such as skin elasticity and joint symptoms showed improvements, while short-term measures like exercise recovery did not.”
