Beauty culture is on the rise and demand for aesthetic enhancement is higher than ever before. This leaves people who struggle with serious, pre-existing skin conditions asking one pivotal question amid the fray: what is the difference between a medical dermatologist and a cosmetic dermatologist? And which do I need?

Those who are affected by acne, rosacea, or psoriasis can begin to rest easier with modern advancements in both medical dermatology and its cosmetic sister. The defining differences in these two practices are as follows:

  • Medical Dermatology is the study and treatment (both medical and surgical) of diseases that affect the skin, hair, and nails.
  • Cosmetic dermatology is primarily targeted toward improving the appearance of the skin and hair through medical treatment.

With many skin conditions–like the aforementioned acne, psoriasis, and rosacea–the disease negatively affects the appearance of the skin. These illnesses can wreak havoc on the skin’s surface, creating unsightly bumps, redness, hyperpigmentation, scarring, and more. The byproducts of skin disease are often deeply emotionally distressing. Patients who wish to not only resolve the illness itself but also restore the beauty of their skin will benefit from both medical and cosmetic dermatology treatments.

At Dr.U Skin Clinic of Los Angeles, Dr. Umar is a double board certified physician, with vast experience in both medical and cosmetic dermatology. Whether you need general skin rash help, psoriasis help, rosacea treatment, skin cancer treatment, or relief from acne, Dr. Umar is able to address the physiology of the problem as well as any accompanying aesthetic malformations. Having a doctor who’s dually qualified allows you to unveil your most beautiful skin in one convenient location, in the hands of a single doctor who can provide a comprehensive course of treatment.

What Conditions are Treated by a Medical Dermatologist?

A medical dermatologist sees and treats a wide array of illnesses affecting the skin, hair, and nails. These can be fungal, viral, bacterial, vascular, or cellular in nature; they can range in severity from mild discomfort to risk of mortality. One thing many of them have in common is their negative impact on the skin’s appearance. They include, but are not limited to:

  • Psoriasis
  • Rosacea
  • Acne
  • Skin cancer
  • Acne keloidalis nuchae
  • Seborrheic dermatitis
  • Cysts
  • Unwanted moles or birthmarks
  • Pemphigus
  • Hyperhidrosis
  • Eczema
  • Vitiligo
  • Contact dermatitis and other rashes

This teenage patient struggled with severe nodulocystic acne, and had tried several types of treatments prior to visiting Dr.U Skin Clinic. Oral and topical medicines had failed to work, and his parents did not want him to be treated with Accutane due to its adverse side effects. His acne also left him with severe scarring.  

The prescribed treatment was a series of photodynamic therapy with Levulan applied to the face, then VBeam laser, followed by Fraxel Dual laser to treat his scars. His results show remarkable improvement only six weeks following his final Fraxel session.

Mild acne pimples that result from environmental debris blocking the skin pores can often become easily resolved. However, there are also more pervasive forms of acne which manifest from blockages that form internally from the skin’s own physiology. More severe types of acne require the help of a skilled dermatologist.

In the video below, Dr. Umar discusses with the young patient the treatment plan he devised for his severe acne and acne scars. The patient affirms that he has benefitted from this treatment in many other ways, such as being more social and spending more time with friends.

Tailoring the Treatment to the Patient in Medical Dermatology

Any dermatologist you choose, for whatever treatment you require, must be well acquainted with the need to tailor their procedure and their devices or medications to correspond with the unique patient needs–of course, with the best outcome in mind. They should be aware of any contraindications or risk factors from case to case.

For instance, laser treatments are the front-running technology for an array of ailments, such as acne and acne scarring, spider veins, rosacea, sagging skin, and much more. However, several lasers are too harsh for people with darker skin, due to highly active melanin. These lasers can actually cause scarring and hyperpigmentation when used on dark complexions. Therefore, the treatment plan  for acne in a Caucasian patient versus an African American patient will look quite different. This is only a simple example, with many other considerations as mentioned above–patient age, skin type, ethnicity, medical history, etc.

Leading Treatments Used by Medical Dermatologists for Skin Conditions

The standard of care for all medical dermatologists falls into three categories, when treating skin conditions:

  • Lasers and light therapy
  • Topical/oral medications
  • Surgery

Lasers and Light Therapy for Rosacea Treatment, Acne, Anti-Aging, and Scars

Lasers have become the go-to tool for targeting many different skin diseases and superficial concerns. The type of light they use, the concentration/wavelength of light, the color of light, and the way the light is dispensed all alter how the laser works.

Some lasers are ablative, meaning they vaporize deep tissue in order to remove unwanted scarring and damage while encouraging tissue repair. These include the Fraxel Repair and other CO2 and Erbium lasers.

Some lasers specifically target red tissue and vascular issues, destroying broken capillaries in order to clear conditions like rosacea. These include the V Beam pulsed dye laser, among others.

There are also non-ablative fractional lasers which use gentle, yet effective heat to encourage the growth of elastin for safe anti-aging benefits. These include the Fraxel Dual laser.

Then there are other types of photodynamic therapy (PDT), which utilize multiple wavelengths, such as blue light to clear away the bacteria that are causing acne lesions. Pulsed dye lasers can also target acne.

A list of common lasers / photodynamic treatment capabilities for skin is as follows (this list is not comprehensive):

  • Fractional lasers–used for skin resurfacing to smooth fine lines, scars, and uneven pigment (including tattoo removal, psoriasis, and vitiligo)
    • CO2, Erbium, Fraxel
    • Photodynamic therapy (PDT)
    • Excimer/exciplex laser
    • Nd-Yag laser
    • Alexandrite laser
  • Vascular lasers–used for all vascular conditions such as rosacea treatment, psoriasis help, and alleviating red acne
    • V Beam
  • Intense Pulsed Light (IPL/photofacial)–used for sun damaged skin in order to reduce excessive redness

Rosacea is a progressive vascular skin disease that manifests as a continued form of redness on areas like the face, neck, and chest. The exact causes are unknown other than the fact that there is an increased amount of blood flow to the skin’s surface. This often follows an environmental exposure to some type of triggers such as food, temperature, exercise, medication or emotional stress.

This patient began noticing redness on his upper chest, which was gradually worsening. Seeking out rosacea treatment early on, he presented to Dr.U Skin Clinic for help. Dr. U restored his skin to a clear and normal appearance after only a single session with the V Beam 585 nm pulsed dye laser.

The patient underwent three sessions with the VBeam laser for his rosacea treatment. Results were seen after just one session.*

Treatment for Unwanted Birthmarks

Birthmarks generally occur as an area of discoloration on the skin. They are oftentimes considered undesirable when they are present on highly noticeable areas of the body, such as the face or neck.

There are two general types of birthmarks:

  1. Vascular birthmarks, which result when surface blood vessels are either prolific and concentrated into a single area, or too large in diameter which increases the flow of blood to the skin.
  2. Pigmented birthmarks which form when pigment-producing melanocyte cells aggregate into a specific region creating a discolored skin area.

These issues can be treated by making precise adjustments at the level of the tiny structures which give rise to unwanted discoloration. Lasers offer an ideal choice of treatment for birthmarks because they can work below the skin’s surface to destroy pigmented producing cells as well as superficial blood vessels that contribute to birthmarks.

Topical/Oral Medications for Skin Rash Help, Psoriasis Help, and Acne Relief

Topical and/or oral medications are often the first line of defense prescribed by a medical dermatologist. Such medications are usually sufficient when seeking skin rash help, and are often very helpful for acne. For more extreme conditions and interventional treatments, such as relief from nodulocystic acne or psoriasis help, a medical dermatologist might prescribe a combination of medications with laser therapy.

Medicines commonly prescribed by a medical dermatologist include (but are not limited to):

  • Antibiotics
  • Antifungals
  • Steroids
  • Corticosteroids

Surgery for Acne Keloidalis Nuchae, Cysts, and Tumors

Surgical procedures are far more invasive than lasers and injectables and require a surgeon with a high level of skill and practice. In most dermatologic cases, surgery refers to the excision of a cyst or tumor. Additionally, it may involve the removal of keloid-like plaques of skin caused by AKN (acne keloidalis nuchae).

Acne Keloidalis Nuchae is a skin condition that often starts as small pimple like bumps on the back of the neck. When left untreated, these lesions will eventually fuse together into a single large tissue mass. At the point, surgical excision of the AKN is the only way to get rid of this manifestation.

This patient struggled for years with the advancement and growth of his AKN condition, over which time he’d been prescribed oral and topical antibiotics, steroids, and steroid injections. Unfortunately, all these treatments failed.

He chose Dr. U for his physician and underwent a specialized excision surgery at Dr.U Skin Clinic. Within a matter of months post-surgery, the AKN was gone and the excision wound was healing well. Dr. Umar intentionally placed the excision site at the base of the hairline, so as to cover the scar–which will grow thinner and lighter with time.

A medical dermatologist should be able to perform specialized surgeries, like this AKN removal at Dr.U Skin Clinic.

Frequently Asked Questions – Medical Dermatologist

Can cosmetic patients benefit from someone who is also a medical dermatologist? Or should they choose someone who only specializes in cosmetic dermatology?

Yes, cosmetic patients can absolutely benefit from a doctor who is also a medical dermatologist, especially if they have a pre-existing skin condition. A dermatologist with expertise in both areas can, for example, offer a more comprehensive and individualized treatment plan for cases that are relatively more challenging due to such medical issues.

At what point should I see a medical dermatologist for skin rash help?

This depends on the severity and size of the rash, how long you’ve had it, and how much pain or discomfort it’s causing. Of course, if there is severe pain, you should visit an urgent care center right away for skin rash help. If you’re unsure whether you should see a medical dermatologist, you may want to text or email a picture of it to your primary care physician for a professional opinion.

When should I see a medical dermatologist for psoriasis help?

If you think you may have psoriasis, schedule an appointment with your doctor right away. Getting psoriasis help early on may prevent the condition from worsening. Any indication of bacterial infection in the skin, accompanied by pain, swelling, tenderness, redness, heat, or pus are potential symptoms of psoriasis.
