Hyaluronic Acid
Hyaluronic acid is another great ingredient to stop premature aging by moisturizing your skin and making it look more youthful.
"As a topical [product], as long as it is in the right formulation, it will make the skin appear more dewy and younger because it improves skin elasticity," Dr. Kavita Mariwalla, a dermatologist in New York City and the founder of Mariwalla Dermatology, tells Harper's Bazaar.
Retinol
Retinol is probably the most important ingredient in an anti-aging skincare routine because it stimulates collagen and helps fight the signs of aging--like wrinkles and age spots.
According to Harvard's HEALTHBeat, "Retinoids reduce fine lines and wrinkles by increasing the production of collagen. They also stimulate the production of new blood vessels in the skin, which improves skin color. Additional benefits include fading age spots and softening rough patches of skin."
Vitamin C
Vitamin C is a popular ingredient for its ability to brighten the skin, helping you achieve a more youthful appearance.
"Vitamin C promotes collagen production, which has the potential to thicken the dermis, diminish fine lines, and is essential for firm, youthful skin," Dr. Patricia Wexler, a dermatologist in New York City. tells CNN.
Glycolic Acid
Glycolic acid is another key ingredient that can help you prevent and reduce signs of aging.
According to Healthline, "It’s very effective at exfoliating skin and reducing fine lines, preventing acne, fading dark spots, increasing skin thickness, and evening out skin tone and texture."
