There's no such thing as a miracle in a jar, but many of today's anti-aging products do move past the hype and turn back the clock just a smidge. And because beauty isn't only skin deep, experts point out that what we put inside our bodies counts nearly as much toward a younger look as what we slather on the outside.
But do they deliver what they promise? Yes and no, she says.
"There's a lot of money to be made from people's fear of aging," Neronha said. "But you cannot stop the aging process you can only manage it."
Skin treatments that work
A big part of that is using what the American Academy of Dermatology (AAD) describes as by far the most beneficial, age-busting product available: sunscreen. Without a daily skin regimen that includes copious amounts of sunscreen (SPF 30 or higher) on all sun-exposed skin, no other anti-aging products matter, Neronha said.
While sunscreen prevents damage, other products can fight the wrinkles, sagging and brown spots that aging skin may already have. Some research-proven ingredients to look for include:
• Retinol Skin care professionals consider this form of Vitamin A the gold standard of effective topical treatments. Also available as prescription strength Retin-A, retinol is an ingredient in myriad over-the-counter products. It ramps up cell turnover in the top layers of the skin, decreasing wrinkles and improving skin tone, according to Neronha.
• Peptides These chains of amino acids act as signaling molecules in cells, telling them to heal, renew and slough away. One of the better-known peptides is argireline, also known as Matrixyl, which softens crow's feet by slowing the contraction of tiny muscles around the eyes, Neronha said.
• Antioxidants Fighting cell damage from free radicals, which are produced when skin is exposed to sunlight and some chemicals, antioxidants can make skin firmer and more radiant, according to Neronha. Wear them, eat them and drink them, experts say. They are available in topical creams with extracts of ingredients such as green tea and pomegranate. Many foods, especially fresh produce and beverages such as fruit juice and various varieties of tea, also contain antioxidants.
• Alpha hydroxyl acids (AHAs) These compounds, which include glycolic, lactic, citric and mandelic acids, can help peel away the top layers of the skin to erase fine lines, Neronha said. AHAs are available in both OTC and prescription strengths.
• Estrogen Available in prescription-strength estriol, the hormone helps maintain skin firmness, said Dr. Pamela Smith, a diplomat of the American Academy of Anti-Aging Physicians and an adjunct faculty member at the University of South Florida School of Medicine in Tampa. Studies show it decreases pore size and depth, she added.
