Acne is an inflammatory disorder of the hair follicle and its associated sebaceous glands in the skin. Acne most commonly occurs in adolescence but may continue into or even begin in adulthood. The face is most commonly affected, but the scalp, chest, and back may be involved. We offer comprehensive array of treatment for acne, including topical and oral medications, including isotretinoin (Accutane), and chemical peels.

Actinic keratosis

Actinic keratosis is a small, rough, raised area found on areas of your skin that have often been exposed to the sun for a long period of time. Most common areas of involvement are scalp, face, ears, lips, back of the hands, forearms, and lower legs. Some actinic keratoses may develop into a type of skin cancer. We treat these lesions to prevent the progression. We offer cryotherapy and topical medications for treatment.

Alopecia areata

Alopecia areata is an autoimmune disease, in which one’s own immune system attacks hair follicles and causes hair to go into resting phase and fall out. It may affect a small spot on the scalp or more extensively involve the scalp and/or body. It is important to distinguish this form of hair loss from other causes for appropriate treatment. Aside from offering comprehensive evaluation for hair loss, we offer localized steroid injections and topical therapy for treatment of alopecia areata.

Atopic dermatitis

Atopic dermatitis, also commonly known as eczema, is a chronic skin condition characterized by pink dry itchy patches. It may begin in infancy or childhood and continue into adulthood. It may wax or wane over time. It is often associated with asthma and seasonal allergies. We guide patients through acute and chronic management of atopic dermatitis with skin care instructions, topical and oral medications, and in severe cases, phototherapy in the form of narrow band ultraviolet light B.

Basal cell carcinoma

Brown spots (Lentigos)

There are different types of lentigos. A common form is a solar lentigo, which appears on the face, upper chest/back, and the back of the hands from chronic sun exposure. They may be treated with cryotherapy, topical medications, or laser treatments.
These lesions must be carefully distinguished by a dermatologist from lentigo maligna, which is a slow growing form of melanoma (see Melanoma) that develops from solar lentigo.

Contact dermatitis

Contact dermatitis can be divided into allergic contact dermatitis or irritant contact dermatitis. Allergic contact dermatitis occurs when you come in contact with an allergen. Red scaly, sometimes blistery patches will first appear hours to days after the contact. Topical and in some severe cases oral steroid treatment are needed.

Irritant contact dermatitis occurs, when you have prolonged contact with irritants, such as water and friction. Those with atopic dermatitis are more susceptible to this condition. Avoidance of irritants and topical treatment are needed to resolve the condition.

Cysts & skin growths

Dysplastic/atypical nevi


Eczema is a broad term for many types of skin inflammation, also known as dermatitis. The most common form of eczema is atopic dermatitis (sometimes these two terms are used interchangeably). However, there are different forms of eczema, including contact dermatitis.


Folliculitis is inflammation of one or more hair follicles. It can occur anywhere on the skin.

Fungal infections of skin, nail, and hair

These conditions may be diagnosed with clinical exam, skin scraping, culturing, or biopsy. They are treated with topical or oral antifungal medications.

Granuloma annulare

Hair loss

There are many causes and possible contributing factors in hair loss. Comprehensive evaluation that may include blood tests is needed to determine the diagnosis and appropriate treatment.



Keloids are a type of scar that usually grows beyond the original border of skin injury. It often causes itching, pain, and discomfort. Localized steroid injection into the keloid scar is often effective in shrinking the scar and relieving the symptoms.


Melanoma is the deadliest form of skin cancer and can be found in people of all skin colors. It often arises on sun-exposed areas but can be anywhere on the skin and very rarely in other organs as well. It can develop from an existing mole or appear on previously normal skin. Early detection through careful skin cancer screening is paramount to timely intervention that can be life-saving.



Psoriasis is a chronic inflammatory skin disease that is classically characterized by thickened, red areas of skin covered with silvery scales. It may cause itching or burning. In the U. S., two out of every hundred people have this condition. Some people will only have discrete, localized areas on the elbows, knees, scalp, or hands, and others may have generalized body involvement. The joints and nails may also be affected with the disease. Psoriasis is not contagious, but it may be found in multiple members of the same family.
Psoriasis cannot be cured, but it can be controlled with treatment. Appropriate treatment can be determined based on a patient’s health, age, lifestyle, and the severity of the disease.


Rosacea is a chronic skin disease that causes redness and swelling, mainly on the face. Those with rosacea may initially develop a tendency to flush or blush easily. It can eventually progress to persistent redness with pimples and visible blood vessels in the cheeks, forehead, chin and nose.
Early diagnosis and treatment can control rosacea so that it is usually not visible or uncomfortable. Early treatment also may stop rosacea from progressing. Aside from appropriate skin care, treatment options include topical and oral medications and laser treatment.

Skin cancers

More than one million skin cancers are found in the U. S., and the rate has been increasing. The leading cause of skin cancer is sun exposure, and people who have fair skin or burn easily in the sun are most susceptible. However, skin cancer can be found in people of all types of skin color.
Three most common types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma.
Basal cell carcinoma is the most common type of skin cancer and can appear in different forms: shiny smooth bump, non-healing sore, waxy scar, or pink scaly patch. Although basal cell carcinoma very rarely spreads to other parts of the body, early detection and treatment are important to prevent extensive destruction of the tissue in the area.
Squamous cell carcinoma is the second most common type of skin cancer. It generally appears as red, scaly or crusty growths on sun exposed areas. Squamous cell carcinoma can grow deep into the tissue and if neglected, can metastasize and become life-threatening.
Melanoma is the deadliest form of skin cancer. See Melanoma for more information.

Seborrheic dermatitis

This is a common, inflammatory skin condition that causes redness with flaky scales on oily areas such as the scalp, face, and/or certain parts of the trunk. People with dandruff may be considered to have the mildest form of seborrheic dermatitis, but they lack the redness or inflammation that is characteristic in seborrheic dermatitis. There is no cure for this condition, but it can be controlled using non-prescription shampoos containing zinc pyrithione, ketoconazole, selenium sulfide, or salicylic acid. In recalcitrant cases, prescription strength topical medications may be used.

Seborrheic keratosis

These are benign wart-like growths that usually begin as small bumps but can gradually enlarge and thicken. It generally occurs in people who are middle aged and older. Commonly, people have multiple of these, but they are not contagious. The cause of these growths is unknown. Because they are benign growths, they generally do not need treatment. However, if they turn black, bleed, itch, or become painful, they need evaluation in order to be distinguished from skin cancer.


Squammous cell carcinoma

Tinea versicolor

Tinea versicolor is a fungal infection of the skin. The fungus interferes with the normal pigmentation of the skin, resulting in small, discolored patches. These patches may be lighter or darker in color than the surrounding skin and most commonly affect the trunk and shoulders. Antifungal creams, lotions, shampoos or in more severe cases prescription-strength medication can help treat tinea versicolor.

Warts & Molluscum

Warts are viral infections caused by Human Papilloma Virus. They often grow on the hands, feet, elbows, and knees, but can be found anywhere on the body. They can cause pain and bleeding in some cases. There are a variety of treatment modalities, including debridement, cryotherapy, application of topical medications, intralesional injection, and laser therapy.
