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 suffer, making it the most common skin disease in the country. While it affects mostly teenagers, and almost all teenagers have some form adults of any age can have it. These blemishes are not life-threatening, but they can cause physical disfigurement (scarring) and emotional distress.


Eczema is the common name for a group of conditions that cause the skin to become red, itchy, and inflamed. The term “eczema” comes from a Greek word meaning “to boil over.” Patients dealing with an eczema flare-up can certainly relate to that description of their inflamed patches of skin. Eczema can range from mild to moderate to severe. In severe cases, the skin can become leathery and develop cracks.


There are several causes of hair loss in women – hereditary causes, crash dieting (inadequate protein), childbirth, birth control pills, medications, medical illnesses (thyroid disease, anemia), surgery, cancer treatments and improper hair care. The most common type of hair loss in all women, regardless of race, is female pattern hair loss (FPHL) or hereditary thinning. It occurs in approximately 30 million women in the United States. Younger and older women alike can be affected, but the typical patient is between 50-60 years od age.


The same cells that give skin its color, the melanocytes, cause moles. A mole is nothing more than a cluster of melanocyte cells. Moles are usually brown or black and can grow anywhere on your skin. Thanks to their melanin, moles can darken with sun exposure and due to hormonal changes, such as during puberty or pregnancy. Moles can change over time, developing hairs, becoming more raised, even changing color. When those changes in height, color, size, or shape occur, that’s when a mole could be transforming from harmless to a potential future melanoma.

Psoriasis is a common, chronic skin condition that is the result of a rapid buildup of skin cells. This causes red, raised, dry, scaly patches, even blisters, to form on the skin. Sometimes, psoriasis affects the fingernails, causing yellowing and small depressions. Psoriasis can range from mild to severe, and in most cases, causes itching and burning.


Rosacea causes redness and visible blood vessels on the skin of the face. It may also create small, red, pus-filled bumps. These signs occur during flare-ups that may last for a period of weeks, even months. Then the signs may subside for a period of time before again recurring. People sometimes mistake rosacea for simple blushing, acne, or an allergic reaction.


Skin cancer refers to the abnormal, uncontrolled growth of skin cells. One in five people will develop skin cancer in their lifetime, according to the American Academy of Dermatology. Fortunately, skin cancer is almost always curable if detected and treated early.


Vitiligo is a skin condition caused by progressive depigmentation; it presents as white patches on the skin. The texture of the depigmented skin is not altered and the condition is not painful, although the affected skin may be much more sensitive to the sun. Vitiligo affects both sides of the body equally, often symmetrically, and the borders of the white patches are irregular but well-defined. White patches may appear gradually or suddenly. Vitiligo is not uncommon, affecting between one-half and one percent of the population. While not serious medically, it can cause emotional distress for the sufferer because of how it makes the skin look.
