Modern treatments use an automated pen-like device. It’s handheld. The head of the device contains a circular arrangement of tiny needles. The device is set to penetrate the skin at a certain depth, making the treatment highly customizable.


As the provider passes the head of rotating needles across the skin, the needles make tiny openings in the epidermis. These minuscule punctures prompt a healing response in the skin without damaging tissue.

Melasma is a common skin condition in which patches of skin on the face darken. Typically, the affected areas are the cheeks, bridge of the nose, forehead or upper lip. The dark patches are often symmetrical. Melasma can occur in anyone, but is much more frequently found among women, especially women who are pregnant when it is called chloasma, and is sometimes referred to as the "pregnancy mask."

 

Although not a painful or dangerous problem, melasma can be very distressing emotionally because of its alteration of the appearance. Melasma is not always a permanent condition. It may disappear in a woman several months after she gives birth, but may reoccur after unprotected exposure to the sun.

A papilloma is a usually benign tumor of the skin or mucous membranes that grows outwardly in finger-like protrusions. It is frequently used to refer to infections caused by the human papillomavirus (HPV), which can cause papillomas of the skin, genitals, mouth, eyes and throat, and, in some women, cervical cancer.

 

Papillomas can form throughout the body. Warts, which are papillomas on the skin, can be found on the hands, feet and knees. They may or not be painful, can grow singly or in clusers, and can be raised or flat, rough or smooth.

vitiligo banner

Vitiligo is a skin condition caused by progressive depigmentation (white patches), usually on the face, elbows, knees, hands, feet, genitals and upper thighs. Vitiligo is not uncommon, affecting between one-half and one percent of the population. The condition appears to be an autoimmune disorder in which immune cells attack melanocytes, the cells that produce pigment.

 

There is also some correlation between vitiligo and three other autoimmune diseases: pernicious anemia, hyperthyroidism and Addison's disease.

sweating hyperhidrosis banner

Hyperhidrosis is a condition that causes excessive sweating on the hands, feet, armpits, face and genital area, or all over the entire body. The exact cause of this condition is unknown, although it often runs in families and begins during childhood.

 

Patients with hyperhidrosis may sweat all over their body or in certain areas. Their skin may become white and wrinkled or red and irritated as a result of the constant moisture, and it may develop an odor as well. Living with hyperhidrosis often causes patients to feel embarrassed, awkward and self-conscious, especially during social situations.

skin tags banner

A skin tag (acrochordon) is a small, soft piece of flesh-colored or dark tissue that is attached to the surface of the skin by a connecting "stalk." Most skin tags develop over time, although some people are born with them. They can develop where clothing rubs against skin, or the skin rubs against itself. Skin tags typically affect people who are overweight, have diabetes, or are older than 40.

 

Although they are almost always benign, and do not cause problems unless they are continuously irritated, many people choose to have them removed for precautionary or cosmetic purposes. Skin tags can itch and, because they can get caught in zippers, clothes or jewelry, sometimes bleed. They are not contagious.

skin cancers banner

Skin cancer, which is the most common form of cancer in the United States, is the result of the abnormal growth of skin cells. Cancer can affect skin anywhere on the body, but most frequently appears on skin that is exposed to the sun. There are more than a million new cases of skin cancer in the United States each year.

 

Every day, skin cells die and new ones form to replace them in a process controlled by DNA. Skin cancer can form when this process does not work properly because of damage to DNA. New cells may form when they are not needed, or older cells may not die, both of which can cause a growth of tissue known as a tumor. DNA damage is often a result of ultraviolet radiation from sunlight or tanning lamps. In some cases, skin cancer affects areas of the skin that have not been exposed to the sun. Certain factors, such as fair skin, moles, a weakened immune system, heredity and age, also increase the risk of skin cancer.

rosacea banner

Rosacea is a common, chronic skin condition that affects up to 10 percent of the population, although many people are unaware that they have it. It usually affects the face, causing redness and the formation of small, pus-filled bumps similar to acne, and, like other skin conditions, can cause emotional distress for the sufferer. Rosacea typically affects fair-skinned women between 30 and 60 years of age. It can first appear during menopause, and is more prevalent in people with a family history of the condition. Although rosacea is a chronic condition that cannot be cured, there are several treatments available to relieve its symptoms and prevent flareups.

TREATMENT OPTIONS

Topical ointments
Oral medications

psoriasis banner

Psoriasis is a common, chronic skin condition. The result of a rapid buildup of skin cells, psoriasis causes red, raised, dry and cracked scaly patches, and even blisters, to form on the skin. In some cases, psoriasis affects the fingernails, causing yellowing and small depressions. Psoriasis can be mild, moderate or severe, and, in most cases, causes itching and burning in affected areas or skin.

 

Psoriasis is the result of an autoimmune disorder, in which skin cells replace themselves every 3 to 4 days, rather than the usual 30, creating a buildup of cells on the skin's surface, and causing symptoms to appear on the scalp, elbows, knees, hands, feet and genitals. Although there is no cure, there are several treatments available to effectively relieve symptoms. In the United States, more than seven million men, women and children have psoriasis.

moles banner

Moles are growths on the skin that are usually brown or black; they may be located, alone or in groups, anywhere on the body. A birthmark is a colored mark that appears soon after a baby's birth. Although many moles and birthmarks are completely benign and pose no health risk, some people choose to remove them because they consider them unattractive. Regularly using a strong sunscreen, and monitoring birthmarks and moles for changes, is highly recommended.

A mole should be examined by a physician if it is larger than 6 millimeters; itching or bleeding; rapidly changing in color, size and shape; multicolored; or located in a difficult-to-monitor area like the scalp.

excessive hair growth banner

Hirsutism is the excessive growth of coarse, unwanted body hair on women. This condition causes women to grow body hair on the face, chest, back or other body parts where men typically grow hair. Hirsutism is a harmless condition, however, many women with this condition may find it embarrassing or emotionally distressing. Hirsutism tends to run in families, and in many cases, the exact cause is never identified.

eczema banner

Eczema is a common skin disorder that manifests itself as itchy skin and a red rash; it is particularly common in infants and young children. Eczema most often develops as a result of an allergic reaction, or an immune-system malfunction. It can cause irritation and inflammation anywhere on the body, but is especially prevalent on the face, the insides of the arms, and behind the knees. In infants with eczema, the scalp is frequently affected.

Eczema can include symptoms of raised and crusty patches, blisters that ooze, or dry and scaling skin. It is diagnosed by physical examination and patient consultation.

Cysts are benign skin lesions which, although sometimes irritating or unsightly, are not usually dangerous. Many benign lesions do not require treatment except for cosmetic reasons. Some, however, may itch, burn, sting, or be otherwise uncomfortable if left untreated and some may lead to possibly malignant changes in the skin.

Contact dermatitis is a skin condition caused by an allergic reaction to certain materials that come into contact with the skin. A common cause of rashes, contact dermatitis appears on the skin after contact with the offending material or substance has taken place. It may occur immediately after contact or may take several days to appear. Typically, contact dermatitis presents as a red, itchy rash. While not serious medically, the condition may be very uncomfortable.

Acne Scars Banner (1)

For many patients, once acne lesions clear up or are removed, they leave behind discolorations and indentations on the skin. In many cases, acne can lead to scarring, especially if it is severe. Scars may form after acne has healed and cleared, and may vary from person to person. Some people may have small flat scars that are not very noticeable and others may suffer from more visible and indented scars on the face or affected area.

acne banner

Acne refers to clogged pores and is found on the face, neck, chest, back, shoulders and arms. It takes many forms ranging from small red spots to pus-filled cysts. Oily skin is sometimes an accompanying complaint. Prolonged, untreated acne may also cause heavy scarring as well.

If you suffer from this skin problem, you are not alone. More than three-quarters of the population between the ages of 12 and 24 have some form of acne, and it is a frequent condition among people in their 30s and 40s as well.

Glycolic acid, salicylic acid and combination acid peels, such as the Vitalize Peel, are used to treat actinic keratoses (precancerous lesions), uneven discoloration, sun damaged or aging skin. These chemicals disrupt the "glue" that holds skin cells together and allow the outermost layers of the skin to be shed gradually, revealing younger, healthier and smoother skin. Since these peels require little "downtime" they are appropriately labeled "lunchtime" peels. The key is that they allow you to return to work without taking any time off.

BOTOX® Cosmetic is a prescription drug that, when injected, temporarily paralyzes muscles. It contains a purified and safe form of botulinum toxin A, which is produced by the microbe that causes botulism. Manufactured by Allergan, Inc., it is used to treat permanent furrows and deep wrinkles in the skin that are formed by the continual contraction of facial muscles.

Hyaluronic acid, or HA, is a natural substance in the body that delivers volume to the skin. Modified HA is the main ingredient behind JUVÉDERM®. Getting treated with JUVÉDERM® helps add volume to different areas of the face without surgery while also temporarily restoring the volume loss beneath the surface. This helps to both smooth out wrinkles and restore a more youthful appearance.

 

There are types of JUVÉDERM® for filling in lines and wrinkles on the face (commonly around the nose and mouth), and to add volume to the lips. On average, JUVÉDERM® typically lasts about 12-18 months until a repeat injection is needed. Schedule a cosmetic consultation appointment today to learn more!

A safe and natural filler that is non-animal derived and naturally found in the skin, Restylane® contained hyaluronic acid and is used to fill deeper folds and wrinkles on the lower half of the face most commonly to restore volume. It can also aid in contouring the lips for a fuller appearance. Since it is non-animal derived, Restylane® does not require allergy pre-testing as is the case with other filler substances.

 

The most common areas for Restylane treatment are the glabellar lines (which run between the eyebrows) and the nasolabial folds (which run from the sides of the nose to the corners of the mouth). Restylane injectable gel is also FDA-approved, for those 21 and older, for enhancing the lips. According to manufacturer Medicis, results can last for up to 6 months, at which point the hyaluronic acid is reabsorbed by the body.
