Dermatologists are physicians who diagnose and treat disorders not only of the skin but of the hair, nails, and mucous membranes as well. Some dermatologists specialize in the treatment and removal of skin cancers or perhaps pediatric dermatology, which deals with dermatological problems common in children, such as birthmarks or acne.

Others specialize in cosmetic dermatology. Rather than treat dermatological diseases, they primarily work to aesthetically improve the skin and, to a lesser degree, the nails and hair. These procedures are generally not surgical in nature and are less invasive than procedures a plastic surgeon might perform. Here is a look at four common anti-aging skin treatments.

Botulinum Toxin

Over time, the facial muscles between and around the eye and forehead droop. Deep lines also develop between the eyebrows, which can lead to an angry appearance. Botulinum toxin temporarily relaxes these muscles and widens the eyes, which leads to a more youthful, approachable, and optimistic facial expression.

Injectable Fillers

Unfortunately, aging leads to a loss of the collagen production that keeps the face full and plump. This leads to sagging jowls, hollowed cheeks, and dark circles under the eyes. Cosmetic fillers will replace this volume temporarily. Results vary, but they can last for up to two years.

Laser Therapy

As people age, their skin's pigmentation can change. Freckles and moles may become darker, or they may become less defined, which can cause the skin to appear "dirty." Freckles may also appear more in unfortunate areas, such as over the upper lip, giving a "mustache" look.

Women who have spent a lot of time in the sun over the years may also notice new dark patches, commonly called age spots. These may be on the face or in other exposed areas, such as the back of the hands. Your dermatologist can treat these darkened areas with a series of laser treatments which will lighten them and even out the skin tone. The finished results will create a more youthful appearance.

Chemical Peel

Dermatologists often use chemicals to essentially exfoliate the skin. These procedures may be used for different conditions, ranging from treating acne scars to reducing the telltale signs of aging. A chemical peel will eliminate or reduce the fine wrinkles and lessen the appearance of deeper wrinkles. It will even out the skin tone and leave a brighter, rosier complexion in its place. A chemical peel will also smooth the skin and improve the texture by removing small blemishes and scarring.
