This involves applying a chemical solution that causes a layer of skin to peel off, revealing regenerated skin beneath that is typically smoother.
Dermatologists use this procedure to treat sun-damaged skin and some types of acne. It can also address cosmetic complaints, such as age spots and lines under the eyes.

Wrinkles, scarring, and reduced facial fullness can be temporarily addressed with injections. A dermatologist can inject Botox or fillers such as collagen and fat during an office visit.
Results tend to last for a few months, and maintaining the effects requires regular injections. However, some people develop antibodies to Botox that make the injections ineffective.

Cryotherapy can be a quick treatment for many benign skin issues, such as warts.
The procedure involves freezing skin lesions — often with liquid nitrogen — to destroy the affected cells.

Dermabrasion can help reduce scar tissue, the appearance of fine wrinkles and tattoos, and potentially precancerous areas of skin.

Using a high-speed rotating brush, a dermatologist removes the top layer of skin.
Excision of lesions
Dermatologists excise skin lesions for several reasons. They may cut away these lesions:
• to prevent a disease from spreading
• for cosmetic reasons
• to prevent reoccurring infection
• to alleviate symptoms
• to diagnose an underlying issue
Depending on the size of the lesion, the person may receive a local or general anesthetic before the removal.

Dermatologists can also use laser surgery to treat a variety of skin issues or cosmetic complaints, including:
• tumors
• warts
• moles
• unwanted tattoos
• birthmarks
• scars
• wrinkles
