Benefits of Choosing JUVA Skin & Laser Center for Your Medical Dermatology Treatments

smiling woman after receiving medical dermatology treatmentsWhile you may have full trust in your dermatologist, the reality is that there are several conditions that a typical dermatologist may not be effectively treating. With such a variety of skin conditions and dermatological needs, there are bound to be differences from one dermatologist to another. However, at JUVA Skin & Laser Center, our dermatologists pride themselves on always having the newest, most tested, and most effective treatment options available.

As part of our diagnostic process, we use Visia complexion analysis technology. The Visia is a computer complexion analysis system that evaluates the condition of your skin. It evaluates parameters such as:

  • Wrinkles
  • UV damage
  • Skin evenness
  • Sun spots
  • Pores
  • Porphyrins

The procedure takes less than five minutes to complete. Based on the analysis generated, Visia will then compare your skin profile to other individuals in your age group. This information helps Dr. Katz develop a regimen to improve your skin and monitor the improvements seen after your treatments. 

Common Conditions Your Dermatologist Could Be Treating Differently

While there are many effective creams on the market, it is often easier and more effective to treat skin conditions with a laser. At JUVA, we pride ourselves on using the best laser technology available because they will deliver better, faster results with no downtime. Rather than having to wait 6-12 weeks for your topical cream to take effect, you can experience immediate or near immediate results with one of our lasers.

In many instances, the following skin conditions may be more effectively treated with one of our lasers than with another dermatologist’s skin creams:

With the aid of our lasers, all of these procedures can be performed in a matter of minutes. You'll experience zero downtime and notice exceptional results in a shorter period of time than if you were using a cream or other topical treatment.

In addition to our laser treatments, we offer injectable treatments that can help you with your age lines, crow's feet, and the sunken areas on your face or hands. We also offer a highly successful skin care line, which was developed from the best-available ingredients, as a supplement to our laser and injectable treatments.

woman with acne breakoutThe most common skin condition in America is acne. Although it's common, finding accurate information about acne can be difficult. This scarcity can make it hard to achieve clearer skin. Acne affects people of all ethnic backgrounds, and about 85-100% of people will be affected by it at some point in their lives. The condition most commonly occurs during puberty, but a rising number of women in their 30s, 40s, 50s and older have acne. 

There are several types of acne:

  • Whiteheads
  • Blackheads
  • Papules
  • Pustules 
  • Cysts
  • Nodules

Additionally, acne can appear on the chest, back, shoulders, neck, buttocks and upper arms. Studies show that people who have acne can have low self-esteem, depression, dark spots on the skin and scars.

There are multiple factors that cause acne. The most common causes are bacterial (p.acnes bacteria), inflammation, abnormal skin differentiation and excess oil production.

There are numerous treatments for acne including:

  • Modification of hygiene regimens
  • At-home/over the counter treatments
  • Prescription topical or oral treatments

There are also physical modality treatments such as:

Aerolase® Neo

The Aerolase Neo is an aesthetic medical device that provides a premium patient experience unrivaled in dermatology and skin care. Uniquely gentle, the Neo offers complete skin rejuvenation, including in a safe, effective, and tolerable treatment for all skin types and tones.

The Neo’s unique 650-microsecond technology is attracted to a combination of melanin, hemoglobin, and water in the skin tissue, which contribute to your skin’s signs of aging. The Neo’s energy passes through the skin to selectively heat these targets without adverse effects, resulting in clear, healthy skin. The 650-microsecond pulse eliminates discomfort during treatment and provides safe, highly effective outcomes for even the darkest skin tones. It also treats acne and achieves excellent skin rejuvenation results. 

Acne breakouts and lesions can result in scarring and appear as elevations (hypertrophic scars) or more commonly depressions (ice pick scarring, rolling scars, etc.). Scar treatments include:

  • ENDY MED laser treatments
  • Fractional CO2 resurfacing
  • Minor skin surgeries
  • Chemical peels
  • Dermal fillers such as Bellafill

Athlete’s Foot

Athlete’s foot is a common fungal disease of the superficial layer of the skin. It is contagious via direct contact from others infected, and from inanimate objects such as locker room floors, public showers or towels.

Treatment can consist of topical or oral treatment, depending on disease severity. After evaluating your condition, Dr. Katz will customize your treatment plan to address your unique needs in the most effective manner possible

Atopic Dermatitis (Eczema)

a hand with eczemaAtopic dermatitis, commonly known as eczema, is a recurrent, red and itchy rash. While it typically appears on the arms and legs, eczema can appear anywhere on the body. It has the tendency to flare with subsequent resolution. An estimated 10% of people worldwide are affected by atopic dermatitis at some point in their life. This condition manifests differently in infants, children and adults. However, flares often subside or become less severe as a person gets older.

There is a hereditary component to eczema, and it can be accompanied by asthma or hay fever. Triggers can include:

  • Extreme temperature
  • Stress
  • Infection
  • Dry skin
  • Irritants
  • Allergens (contact allergens can be determined by patch testing)

No cure has been found for the condition, but prescription treatments and self-care measures can relieve itching and help minimize new outbreaks. A consultation with one of our providers at JUVA will help find the best treatment course that suits your needs.

Birthmarks and Port-Wine Stains

Birthmarks are a very common congenital skin mark that is typically benign. They are caused by the overgrowth of one or more different types of tissues within the skin. The six most common types of birthmarks are:

  • Café au lait spot
  • Congenital nevus
  • Slate gray nevus (Mongolian spot)
  • Port-wine stain
  • Salmon patches/stork bites
  • Hemangioma

The type, size, and location of the birthmark are some of the most common factors which will determine whether treatment is required, as well as the ideal course of action. Salmon patches, port-wine stains and hemangiomas can be treated with laser technology such as the pulse-dye laser.

Diseases of the Hair

Our dermatologist and experienced staff can help you improve any hair disease you may have, including excess body hair and Alopecia.

Defined as hair loss, Alopecia can have many different patterns and is classified into two main categories:

  • Scarring
  • Non-scarring

The most common concern we see in our patients is generally referred to as androgenetic alopecia (male or female pattern hair loss).

From genetics to hormones, a variety of factors interplay in the hair loss process. Fortunately, newer, clinically proven treatments have been developed. At JUVA, we offer a variety of hair restoration options, including platelet-rich plasma therapy (PRP) and Vectus laser treatment. Typically, PRP is supplemented with Viviscal, which is an oral and topical supplement that works synergistically with PRP.

Diseases of the Nails

Onychomycosis is a fungal infection of the nails. It can occur on the finger and toenails. Not all nail thickening or discoloration is a fungal infection. Age, trauma, underlying health conditions and yeast infections can mimic fungal infections. An assessment by one of our board-certified dermatologists will help to identify the underlying cause of nail issues.

At JUVA, we have numerous treatments for nail fungus. Laser therapy is one of the most common and effective solutions for this condition.

Dry Skin

Dry skin, is a condition consisting of itchy, scaling skin beyond what is typical for an individual. There are numerous causes of dry skin, including:

  • Age
  • Medications
  • Previous extent of ultraviolet exposure
  • Seasonal changes
  • Underlying medical conditions

At JUVA, our dermatologists are skilled in dealing with various dry skin conditions and can help to alleviate it. Common treatments include at-home therapies, hygiene routine modifications and prescription therapies.

Excessive Perspiration

Excessive sweating, also known as hyperhidrosis, is a common condition that affects the hands, armpits, soles and face. Hyperhidrosis can be caused by medications, stress or underlying medical conditions.

Fortunately, there are numerous therapies for hyperhidrosis. We typically recommend BOTOX® Cosmetic and laser therapy (SculpSure™) for the most effective results.



Impetigo is a contagious bacterial condition that typically develops in children, particularly on the face. Older adults, diabetics and people with weak immune systems will likely develop the more serious version known as ecthyma.

When the right antimicrobial treatment is used, the eruption usually clears within 7 to 10 days. Impetigo usually is not dangerous; however, complications can develop such as scarring, cellulitis (deeper skin infection) and kidney problems.


Keloids are elevated scars that extend beyond the original borders in areas of trauma (previously injured skin, such as burns or lacerations). Keloids can also spontaneously occur without any prior trauma to the area. Common symptoms include itching and pain.

Keloid treatment usually consists of cortisone injections. At JUVA, we will implement a unique treatment regimen tailored to the location, size and symptoms of your scars.


Melasma is a common disorder of persistent, dark patches on the face. Some causes include hormone level changes in women during pregnancy or oral contraceptive use. Certain medications and ultraviolet light exposure can also contribute to this condition. Darker skinned individuals are more susceptible to melasma.

Our doctors and staff at JUVA have a variety of treatments available for melasma, including:

  • Our proprietary lightening creams
  • Laser treatment with the Picosure laser
  • Chemical peels
  • Dermabrasion

Mohs Surgery

Mohs surgery, also known as Mohs micrographic surgery, is a surgical procedure used to treat skin cancers and other atypical growths. This is known as a tissue-sparing surgery that does not require general anesthesia. The surgery is performed using a local anesthetic and is done on an outpatient basis.

Basal cell and squamous cell carcinoma are the most common types of skin cancers treated. Mohs surgery is utilized for skin cancers that meet certain criteria, including:

  • Skin cancers located in anatomically sensitive areas, such as the mouth, nose, eyes, ears, hairline, hands, feet and genitals. These are areas where you want to preserve as much healthy tissue as possible.
  • Cancers that are large or have an aggressive subtype.
  • Cancers that have the potential for a risk of recurrence or that have recurred after previous treatment.
  • Skin cancers that are ill-defined.

The process consists of the progressive removal and examination of thin layers of skin, known as stages. These layers contain cancer until all of the cancerous tissue is removed. The surgical technique is very precise and, in most cases, can take a few hours. However, sometimes more complex cases can last an entire day.

The unique aspect of the Mohs technique is that it allows surgeons to ensure and verify that all cancer cells have been removed at the time of the surgery. Therefore, Mohs has the highest cure rate of all skin cancer treatments.

At JUVA Skin & Laser Center, we have a surgery team dedicated only to Mohs surgery. If your provider determines you need Mohs, you will be treated in our office without the need for further referrals.


Moles are one of the most common growths on the skin. Moles vary in appearance from light tan to dark brown, and they can even appear as black, red, pink or blue. Moles can be wrinkled, raised, flat or smooth. Some moles even have hair growth. They can show at birth or can develop as you get older. Most moles appear before forty years of age.

Moles can develop anywhere on your body, including:

  • Your scalp
  • Beneath your nails
  • Between toes and fingers
  • Your armpits

Many medical professionals, including the Mayo Clinic, recommend this ABCDE guide for self-examination to assess moles and determine if they could be considered “atypical:”

  • One-half of the mole does not look like the other half
  • The outline of the mole is irregular
  • More than one color can be seen, such as brown, black, red, blue and white
  • A mole larger than 6 mm (1/4 inch), which is roughly the size of a pencil eraser
  • Evolving: Changes in the mole over time

The appearance of cancerous (malignant) moles varies greatly. Malignant moles may showcase all of the aspects listed above, or just one or two. Changes in moles, from size to color to shape, will warrant a skin check. It is imperative to be evaluated for melanoma. Some people have a higher than normal chance of developing moles that become cancerous.


Psoriasis is a skin condition that manifests as itchy, persistent, red, thickened, scaly lesions. There is a hereditary component to psoriasis, as 30% of patients have a family member with the condition. There are several forms of psoriasis. Some can be triggered by certain situations like emotional stress, injury to the skin, infection and various medications.

There are numerous topical, oral and injectable treatments for psoriasis. At JUVA, we have the X-TRAC excimer laser, which is one of the most effective and safest psoriasis treatments available.


Rosacea develops in the center of the face and involves chronic inflammation. It tends to primarily affect those of northern European ancestry, who are between the ages of 30 and 60.

There are four types of rosacea:

  • Redness (Telangiectatic): The face is frequently flushed, which may continue to develop into a persistent redness located on the nose and central face
  • Acne (Papulopustular rosacea): This form results in bumps and pus-filled acne-like lesions, which can arise with or without redness
  • Rhinophyma (Glandular growth): This form results in progressive oil gland enlargement and thickening skin in the nose area, on the chin and/or between the eyebrows
  • Ocular rosacea (Eye discomfort): Persistent eye and eyelid reddening is experienced, with or without discharge and a burning or gritty sensation

At JUVA, we have newer technologies to treat various types of rosacea such as our pulsed dye laser and proprietary topical medications.


Shingles is a viral infection that causes a painful rash. It appears as a group of blisters that wrap around a side of the face, neck, body, leg or arm. The most common location for a shingles outbreak is the torso.

Shingles is typically preceded by a prickling sensation, followed by a rash. Flu-like symptoms can develop. The rash can be painful.

Symptoms or signs of shingles include:

  • Itching
  • Touch sensitivity
  • Red rash beginning a few days after the pain
  • Tingling, numbness, pain or burning
  • Blisters filled with fluid that crust over and break

Vaccines can help reduce the risk of shingles, and early treatment can help shorten the infection. Treatment success depends on how quickly treatment is started. It is best to start oral treatment as soon as the blisters develop to ensure the quickest resolution and to minimize complications.

Skin Cancer (Melanoma)

Melanoma is the most serious skin cancer that is encountered on a daily basis, as it has the significant potential to spread deeper into the body. In recent years, it has increased in the frequency of diagnosis. Melanoma can arise from a benign-appearing mole or from healthy, mole-free skin.

Melanoma usually occurs on areas of the skin that are exposed to the sun, but it can be found anywhere on the body, including the eye, mouth, anus and genital area. Melanoma usually develops for men on the head, neck and trunk. For women, it most likely develops on the legs and arms. There are several genes identified in melanoma development.

The appearance of cancerous (malignant) moles varies greatly. Please see our ABCDE checklist in the mole portion of this page to determine which moles can be considered “atypical.”

Risk factors for developing melanoma include:

  • Family history of diagnosis
  • Fair skin/light eyes
  • A tendency to freckle
  • A large number of moles
  • History of frequent sun exposure (especially in childhood)
  • History of sunburns
  • History of indoor tanning
  • A decreased immune system, which is often found in transplant patients and patients with HIV/AIDS

If you are due for a skin check or have moles you are concerned about, please schedule a skin check appointment with one of our providers as soon as possible.

Skin Tags or Skin Biopsy

A skin biopsy involves removing a sample of your skin to be evaluated under a microscope in order to facilitate diagnosis. There are two main types of skin biopsies:

  • Shave biopsy: Using a razor-like tool, the top layers of skin in a small area are removed
  • Punch biopsy: Using a circular tool, the skin is punctured to remove deeper layers of skin in a small section

After the procedure, the samples are sent to a pathology laboratory for evaluation. We will then receive a written report detailing the results. A completed report may take several days or a couple of weeks, depending on the type and indication for the biopsy.

Spider Veins

Spider veins are dilated, superficial blood vessels. They can manifest as red, blue or purple vessels, usually less than 1-3 mm wide and several millimeters to centimeters in length. They may disappear temporarily when pressed on with one finger.

Spider veins are common in all types of people and can be caused by aging, sun damage or genetics. When found on the legs, it may not indicate that you have a vein disorder such as an underlying deep vein problem or varicose veins. However, spider veins are commonly found with a variety of other diseases.

This condition can appear anywhere on the body including:

  • Nose
  • Cheeks
  • Chin
  • Face
  • Legs
  • Thighs
  • Ankles
  • Below the knees

Varicose Veins

Varicose veins are veins that are swollen and twisted, which can be seen and sometimes felt protruding from the skin. They commonly occur on the legs, but can be seen in other parts of the body.

This condition occurs when one-way valves that are used to keep the blood flowing to the heart are backed up, causing pools of blood to build up within the vein. When this occurs, the veins swell and become visible. Although varicose veins are very common, people who are at a higher risk of developing them are females, obese people and those who live a sedentary lifestyle. They are also more common during pregnancy.

At JUVA Skin & Laser Center, our providers have numerous treatments for varicose veins including sclerotherapy and the Cynergy laser.


Vitiligo is an autoimmune disease which causes the immune cells of the body to attack the melanocytes within the skin. This results in a localized loss of pigment, which can be on the skin or even hair. Vitiligo can be associated with underlying conditions such as:

  • Thyroid disease
  • Alopecia areata
  • Diabetes mellitus
  • Addison disease
  • Myasthenia gravis

It occurs at all ages and can affect people of all races.

At JUVA, we have the XTRAC excimer laser, which is one of the most effective treatments in restoring the pigment in vitiligo.
