Skin Cancer

Dr. Walls has extensive training in the treatment of skin cancer, which includes three main types:

Basal cell carcinoma

This is the most common form of skin cancer and resembles “a flesh-colored, pearl-like bump or a pinkish patch of skin,” according to the American Academy of Dermatology. Basal cell carcinomas often occur on the head, neck and arms, but can appear anywhere on the body. People who are fair-skinned or spend a lot of time in the sun are especially susceptible to this type of skin cancer. Learn more.

Squamous cell carcinoma

This is the second most common form of cancer and frequently looks like “a red firm bump, scaly patch, or a sore that heals and then re-opens,” according to the American Academy of Dermatology. Learn more.


This is the deadliest form of skin cancer and often begins in an existing mole or “suddenly appears as a new dark spot on the skin,” according to the American Academy of Dermatology. Learn more.

Mohs Micrographic Surgery

Dr. Walls also has extensive training in Mohs micrographic surgery for the treatment of non-melanoma skin cancers. Mohs surgery is a specialized, highly effective technique for the removal of skin cancer. The procedure was developed in the 1930s by Dr. Frederic Mohs at the University of Wisconsin and is now practiced throughout the world. Mohs surgery differs from other skin cancer treatments in that it permits the immediate and complete microscopic examination of the removed cancerous tissue, eliminating all “roots” and extensions of the cancer. Learn more.


Acne is an inflammatory disease of the sebaceous glands, characterized by pimples, blackheads, whiteheads and in severe cases cysts, on the face, back, chest and upper arms. At Aspen Center for Cosmetic Medicine, we typically treat this condition with blue light therapy, which reduces acne-causing bacteria and shrinks sebaceous glands; prescription therapy; and a supplement regimen. For severe acne, blue light therapy may be combined with levulinic acid to produce a more aggressive treatment. Additionally, cortisone injections may be used for stubborn cysts, followed by chemical peels to eliminate acne scarring. Learn more.


Rosacea is a disorder characterized by redness on the cheeks, nose, chin or forehead; in some cases, visible blood vessels, small, red, solid bumps and pus-filled bumps also may occur. Treatment includes IPL (intense pulsed light) therapy to reduce redness, and skin care and medication to treat the associated acne. Learn more.

Skin Cancer Screening

People of all colors and races can get skin cancer, and an estimated 1 in 5 Americans will develop it during his or her lifetime. However, if diagnosed and treated early, skin cancer has a high cure rate. A yearly skin screening can alert you to changes in your skin and aid in the early detection of skin cancer. We use dermoscopy, the latest technology for early detection.

Actinic Keratosis

An actinic keratosis (AK) is a rough, dry, scaly patch that forms over time on sun-exposed skin. Commonly found on the face, neck, hands and forearms, AKs can become skin cancer in a small percentage of cases. We treat AKs with levulinic acid and photodynamic therapy, as well as liquid nitrogen. Learn more.

Moles and Skin Tags

Moles and skin tags (small flaps of tissue that hang off the skin by connecting stems) are common and many people have them removed for cosmetic reasons. Skin tags are harmless but moles should be evaluated on a yearly basis, as some can be problematic. Any changes in a mole’s appearance should be checked by a physician.

Other Skin Disorders and Infections

We provide medical care for a number of other skin disorders and infections, including eczema, allergic contact dermatitis, melasma (also known as the mask of pregnancy), rashes and warts. After each patient is evaluated, a comprehensive treatment is recommended.


A migraine headache is a debilitating condition that can cause throbbing or pulsing pain on one side of the head and may be accompanied by nausea, vomiting and sensitivity to light and sound. Botox has been approved by the FDA as a preventive treatment for chronic migraine headaches in adults.
