The focus of the Dermatology and Cosmetic Laser Center of Huntington is to provide patients with outstanding care in a caring environment. Here, the health and beauty of your skin is our priority. There are literally hundreds of conditions that pose a threat to the health and beauty of the skin. Under the care of your board certified dermatologist, your skin concerns can be expertly and caringly handled.


A common condition for which professional dermatological care may be warranted is acne. Many people think that acne is a temporary problem that affects teens. In truth, acne can occur at any age.

There are cases of acne that respond well to commercial topical medication. However, over-the-counter products can lead to further irritation, so they should be used with caution. If skin becomes more inflamed with the use of an over-the-counter topical solution, or acne does not clear within four to six weeks, professional care by Dr. Koreen would be beneficial. The Dermatology and Cosmetic Laser Center of Huntington offers several different acne-fighting treatments. Each patient is treated as an individual, with a care plan designed around skin type, age, and the severity of acne. For some, topical medication may be sufficient whereas others may require oral medication or procedures such as microdermabrasion, peels, or Isolaz laser to treat existing acne and avoid acne scarring.


Eczema is a chronic skin condition for which there is no known cure, that can cause physical discomfort and emotional distress. With professional care, it is possible to learn what triggers eczema flare-ups and how to manage them with lifestyle changes, proper moisturizers, and prescription. Patients may also benefit from patch testing to rule out contact dermatitis.


For millions of Americans, chronic psoriasis affects quality of life. This condition can be uncomfortable and disfiguring. Like eczema, psoriasis may occur in flare-ups and remissions. Instances of active inflammation may be triggered by infection, medications, or stress, among other factors. This condition may also be associated with other disorders affecting the autoimmune system, such as metabolic syndrome or arthritis. We treat psoriasis based on the individual patient, and may include therapies such as topical, oral, and / or injectable medication, ultraviolet light treatments, or Xtrac laser.

Skin issues, chronic or not, can cause embarrassment and loss of confidence. The team at the Dermatology and Cosmetic Laser Center can help you gain control over your skin’s health and appearance. Call our office at (631) 417-3300 to schedule your visit.
