Anti-aging skin care products come in all forms, shapes and sizes, including dietary supplements that contain ingredients touted to benefit the skin. Here’s some information on some of the forms and types of anti-aging skin care products that will help you make intelligent purchasing decisions.

Exfoliants and AHAs (alpha hydroxy acids) work to remove the layer of dead skin cells that sits atop the younger, firmer skin beneath. Exfoliants generally take the form of scrubs that contain tiny plastic spheres, or substances like ground nutshells. Exfoliants gently abrade and polish the skin. AHAs come in the form of lotions or serums and chemically break down the walls of the dead skin cells, allowing them to sluff off.

Eye treatments are special classes of anti-aging skin care products. The skin around the eye is very thin, delicate and prone to fine lines and tiny wrinkles. Many cosmetics made for the face can irritate the eye, so pure, gentle formulations are the norm. Look for botanicals like soothing aloe vera. The product you choose should be hypoallergenic and fragrance-free. Look for ingredients like the proven antioxidant vitamins A, C and E.

Some eye treatments contain ingredients to reduce puffiness and undereye circles.

Many women develop fine lines around the lips. There are targeted lip treatments that can help – another specialized form of anti-aging skin care products. Lip treatments should help keep lipstick from feathering or bleeding, and should moisturize and hydrate. Many lip treatments contain light-diffusing ingredients that scatter light rather focus it, softening the look of fine lines and wrinkles.

Night treatments are another unique class of anti-aging skin care products. Designed to stay on the skin overnight, these products often contain higher levels of key ingredients than a day treatment would. Night treatments are often richer in emollients, vitamins and botanicals, providing intensive therapy for stressed and damaged skin.

If you’re using a typical skin care regimen of cleanser, toner and day cream, you might benefit from a targeted treatment for lips or eyes. Weekly exfoliation with a scrub works hand in hand with AHAs. Choose your products wisely and use them regularly, and your skin will have a healthy, radiant glow.
