Acne is the term for the blocked pores (blackheads and whiteheads), pimples, and deeper lumps (cysts or nodules) that can appear typically on the face, neck, chest, back, shoulders and upper arms. Seventeen million Americans currently have acne, making it the most common skin disease in the country. While it affects mostly teenagers, and almost all teenagers have some form of acne, adults of any age can have it. Acne is not life-threatening, but it can cause physical disfigurement (scarring) and emotional distress.  Treatment for acne varies depending on the type and severity of lesions, as well as the patient's skin type, age and lifestyle.  


Rosacea, frequently referred to as "adult acne", is a chronic skin condition involving inflammation of the cheeks, nose, chin, forehead, and/or eyelids. It is characterized by redness, broken blood vessels, and flushing of the face. Patients may also experience pimples, swelling, and a burning or stinging sensation. Rosacea is often seen in patients with lighter skin color although we do see it in all skin types. Triggers for rosacea include aclohol, caffeine, spicy foods, sunlight, and extreme temperature changes among others. There is no cure for rosacea, but fortunately, there are many treatment options. Topical creams and gels, oral antibiotics, and laser treatment for broken blood vessels are just a few of these options available to our patients.

Skin Cancer

Skin cancer is the most common form of cancer in the United States. The most common types are basal cell cancer and squamous cell cancer. The most common locations for these cancers are on the head, face, neck, hands and arms. Any growth that is not healing, bleeds, or is changing should be evaluated to rule out skin cancer. Most patients need yearly skin cancer screenings.  Melanoma is a less common but more dangerous form of skin cancer. Melanoma is usually characterized by asymmetry, irregular borders, uneven color, or large diameter. Melanoma can spread to lymph nodes and other internal organs. Early detection is important for a better prognosis.  


Moles or "nevi" are composed of groups of pigment producing cells called melanocytes. They are important to monitor because of their potential risk for  turning into malignant melanoma. Dypslastic moles, which are clinically and microspically atypical in appearance, are putative precursor lesions of melanoma. Most people need yearly skin examinations to screen for melanoma and other skin cancers. People with numerous moles or a family history of melanoma should be carefully monitored with more frequent full skin examinations. It is important to watch for any change in color, size, or shape of exisiting moles and to let us know if these changes occur. Moles may be removed because they are clinically worrisome.


Warts are common growths that can appear anywhere on the body. They are caused by various strains of the Human Papilloma Virus or HPV. Warts can  be extremely stubborn to treat but will ultimately resolve once your immune system mounts a response. We offer a multitude of treatment options for warts. We find that what works best for one person may not work as well for another. We utilize a full arsenal of wart treatments including liquid nitrogen, canthacur, and surgical treatment among others. We also recommend over-the-counter salicylic acid treatments between office visits. We may also recommend prescription creams to boost your immune response. Warts can be extremely frustrating, but with a little persistence, we can help you make them disappear.


About 15 million of people in the U.S. suffer from some form of eczema, including a large percentage of infants and children. Symptoms vary from person  to person but often include dry, red, itchy patches on the skin. If untreated and chronically scratched, eczema can potentially become infected.  All eczema patients need to increase their use of  moisturizing lotions and decrease the length and temperature of their shower or bath. Treatment options include corticosteroids creams and ointments, antihistamines, and non-corticosteroid creams and ointments such as protopic or elidel. Oral anbitiotics can be prescribed in cases of an infection. With a few lifestyle changes and treatment options, most cases of eczema can be well controlled.


Psoriasis is an inflammatory skin condition that appears as silvery white scaly plaques. Over seven million men and women in the U.S of all ages have some   form of psoriasis. The most commonly affected areas are the scalp, elbows, knees, hands, feet and genitals.  Psoriasis cannot be cured but it can be managed successfully. Treatment depends on the type, severity and location of psoriasis; the patients age, medical history, and the effect the condition has on the patient's quality of life. The most common treatments are topical medications, phototherapy, and oral or injectable medication (for severe cases).
