Anti-Aging Modalities
Having worked in specialties focused on anti-aging and aesthetics (not that aging isn’t aesthetic), there are some major takeaways and things I have started applying to my life to help reduce signs of aging in the future.
I will note that genetics does have to do a lot with the aging process and how quickly one ages, but there are things one can do to improve outcomes. Per an article published in the Journal of Clinical, Cosmetic, and Investigational Dermatology, skin aging is influenced by heritable and environmental factors. Up to 60% of skin aging variation can be attributed to genetic factors, while 40% is due to non-genetic factors.
The American Academy of Antiaging Medicine encourages the dietary intake of antioxidants, lifestyle modifications, and increased exercise. These include slim body maintenance, smoking cessation, active social maintenance, stress reduction, a healthy diet, and psycho-stimulation (which activates neural pathways and fosters neural plasticity, leading to enhanced cognitive functioning and emotional regulation, and can be achieved through meditation and mindfulness, cognitive exercises, social interaction, environmental exposure, and physical activity)
Interventional studies indicate that it is possible to delay skin aging and improve skin conditions through the administration of nutritional supplements such as uric acid, glutathione, vitamins C and E, carotenoids, copper, and selenium.
Vitamins, polyphenols, and flavonoids (found in plant foods) reduce collagen breakdown by reducing the concentration of free radicals which cause fine lines and wrinkles, a dull, uneven skin tone, increased dark spots, and sagging skin. Retinols, peptides, and growth factors promote collagen production, reduce sagging skin, and improve skin texture and hydration.
It has been reported in the Journal of Investigative Dermatology that ~80% of skin aging on the face is due to UV exposure. The best defense is prevention through photoprotection which consists of utilizing shade when outdoors; wearing protective hats, clothing, and sunglasses; and applying SPF ≥ 30 broad-spectrum tinted sunscreen. The Journal of the American Academy of Dermatology provides evidence that daily sunscreen application plays a major role in the prevention of photoaging (premature skin aging due to sun exposure). If you’re late to the game, vitamin A, retinoids, and carotenoids have shown benefits in the prevention and reversal of photoaging.
Some other good things to know and keep in mind:
Drink alcohol in moderation: it dehydrates the skin, which can result in the faster onset of wrinkles and reduced elasticity.
Stay hydrated: an International Journal of Cosmetic Science study found that drinking 2.25 liters of water every day for 4 weeks improved skin density and thickness, helping the skin look more plump. Another study found that drinking ~2 cups of water increased blood flow to the skin, thereby increasing moisture and spreading nutrients.
Medical aesthetics- I turn to this last because these things are expensive and I believe they should be used only as needed and when desired in a healthy manner. This includes botox, fillers, and skin laser treatments!
