Retinol
Vitamin A and its derivatives are powerful and proven antiaging antioxidants. Retinol is a topical ingredient proven to promote collagen production and plump out skin, reducing fine lines and wrinkles. It also improves skin tone and color, and reduces mottled patches (hyperpigmentation) on the skin.
Many dermatologists prescribe retinol’s stronger counterpart, tretinoin, or similar products to slow skin aging, improve irregular pigmentation, and clear up acne. Over-the-counter products containing retinols may be weaker, but are still effective in improving skin appearance.
Although retinol hydrates the lower layers of the skin (the dermis and hypodermis), it sometimes causes the top layer (the epidermis) to become dry and flaky. Be sure to wear moisturizer when using it or speak to your dermatologist about alternatives.
Vitamin C
As you age, your body slows down its production of collagen and elastin, which keeps skin strong, flexible, and resilient. Evidence suggests that the antioxidants found in vitamin C may stimulate the production of collagen and minimize fine lines, wrinkles, and scars.
Vitamin C is being added to skin-care products such as creams and lotions. This is one ingredient that may work best when eaten, so stock up on oranges and broccoli. If you want to use a topical vitamin C lotion, ask your dermatologist which one would be right for you.
CoEnzyme Q-10 (CoQ-10)
Your body naturally produces CoQ-10 to neutralize free radicals in cells, but as you age, the levels of CoQ-10 go down. That may make skin cells more susceptible to damage by free radicals. That’s the rationale behind the use of the antioxidant in skin-care products such as toners, gels, and creams, to be used alone or with a moisturizer. One study shows that CoQ-10 helps reduce wrinkles around the eyes (crow’s feet).
CoQ10 is bright orange, so products containing it will be orange or yellow.
Hyaluronic Acid
Hyaluronic acid is incorporated into skin-care products to reduce the effects of aging. Your body produces hyaluronic acid naturally, keeping tissues cushioned and lubricated. It’s found in skin, joint fluid, and connective tissues. Age, smoking, and an unhealthy diet lead to drops in production over time.
Products containing hyaluronic acid may help smooth out skin. It’s especially effective when combined with vitamin C products.
Green Tea Extract
Like antioxidants, the polyphenols found in tea also have been shown to fight free radicals. Drinking green tea may help ward off cancer, infection, and cardiovascular disease.
Early studies have found the ingredients in tea can reduce sun damage and may protect skin from skin cancer when applied topically. Using green tea extract under sunscreen may yield a double dose of protection. An anti-inflammatory, polyphenols in creams and lotions may also slow signs of aging and reduce sagging skin and wrinkles
