Advanced dermatology focuses on skin conditions that need more than standard care

Advanced dermatology treats skin diseases that don't respond to basic topical creams or oral medications, or conditions where the underlying cause requires specialized equipment or techniques. These include severe acne, persistent eczema, psoriasis, rosacea, skin cancer, scarring, and pigmentation disorders. The treatments use tools like lasers, light therapy, chemical peels, injectable medications, and surgical procedures that a general dermatologist may not perform in-office.

The difference between standard and advanced dermatology is not always clear-cut. A dermatologist might handle mild psoriasis with topical steroids, but refer severe psoriasis to an advanced practice that offers biologic injections or phototherapy. Similarly, a small mole removal happens in any dermatology office, but Mohs micrographic surgery for skin cancer requires specialized training and happens in a surgical center or hospital.

Key Takeaways

  • Advanced dermatology uses equipment and techniques—lasers, light therapy, injectables, and surgical procedures—that treat conditions standard topical or oral medications cannot control.
  • Biologic medications, which target specific immune pathways, are often reserved for severe psoriasis, eczema, and other inflammatory skin diseases that have not responded to other treatments.
  • Laser and light-based treatments address scarring, pigmentation, unwanted hair, and vascular lesions, and require specialized equipment and training to perform safely.
  • Mohs micrographic surgery removes skin cancer layer by layer under a microscope, preserving healthy tissue and offering the highest cure rate for certain cancers on the face and neck.
  • Insurance coverage varies widely depending on whether the treatment is considered medically necessary or cosmetic, and your plan's specific rules about dermatology referrals and out-of-network providers.

Biologic medications for severe inflammatory skin disease

Biologic drugs are made from living cells and target specific parts of the immune system that drive inflammation. They are injected under the skin or given intravenously, usually every two to four weeks. Common biologics for skin disease include dupilumab (Dupixent), which blocks interleukin-4 and interleukin-13 and is used for moderate to severe atopic dermatitis and eczema; secukinumab (Cosentyx) and ixekizumab (Taltz), which block interleukin-17 and treat psoriasis and psoriatic arthritis; and adalimumab (Humira), which blocks tumor necrosis factor and treats psoriasis, hidradenitis suppurativa, and other conditions.

Biologics are typically prescribed only after a patient has tried and either failed or could not tolerate conventional treatments—usually topical steroids, calcineurin inhibitors, or oral medications like methotrexate or cyclosporine. They work faster than conventional drugs in many cases and can clear skin significantly, but they suppress parts of the immune system, which means you will need regular blood tests and screening for infections before and during treatment. Cost is high; a single injection can run $1,500 to $3,000 before insurance, though most insurance plans cover them once medical necessity is documented.

Laser and light-based treatments for scars, pigmentation, and vascular lesions

Laser and light therapies use focused beams or broad-spectrum light to target specific structures in the skin. Different wavelengths penetrate to different depths and affect different targets—melanin (the pigment in brown spots and tattoos), hemoglobin (the protein in blood vessels), or collagen (the structural protein in scars).

Ablative lasers, such as CO2 and erbium lasers, vaporize the outer layers of skin and are used for deep wrinkles, severe acne scars, and precancerous lesions. Non-ablative lasers, such as fractionated lasers and Nd:YAG lasers, heat the deeper layers without removing the surface, making them safer for darker skin tones and requiring less downtime. Intense pulsed light (IPL) uses a broad spectrum rather than a single wavelength and treats sun damage, rosacea, and broken blood vessels. Laser hair removal targets melanin in hair follicles and requires multiple sessions because hair grows in cycles.

Sessions typically last 15 to 45 minutes depending on the area treated. Ablative treatments require a week or more of healing and visible redness or crusting. Non-ablative treatments may cause mild redness that fades in hours to days. Most people need multiple sessions—typically three to six for scars or pigmentation, and six to eight for hair removal—spaced four to six weeks apart. Cost ranges from $200 to $500 per session for small areas and $1,000 to $3,000 for full-face treatments, and insurance rarely covers laser work unless it is for a medical condition like rosacea or precancerous lesions rather than cosmetic improvement.

Mohs micrographic surgery for skin cancer

Mohs surgery is a technique for removing skin cancer—usually basal cell carcinoma or squamous cell carcinoma—with the highest cure rate and the least damage to surrounding healthy skin. The surgeon removes the visible tumor plus a thin margin of normal-looking tissue, then when ready examines it under a microscope. If cancer cells are still present at the edge, the surgeon removes another layer from that specific area and checks again. This process repeats until the margins are clear, which usually takes one to three rounds but can take longer for large or aggressive tumors.

Mohs is performed in an outpatient surgical center or dermatology office under local anesthesia. The entire procedure, including waiting for pathology results between rounds, typically takes two to four hours. Cure rates are 95 to 99 percent depending on tumor type and location, compared to 85 to 95 percent for standard surgical excision. Mohs is especially valuable on the face, ears, eyelids, and other areas where preserving tissue is important for appearance and function. After the cancer is removed, the wound is either left to heal on its own, closed with stitches, or reconstructed with a skin graft or flap depending on the size and location.

Insurance covers Mohs surgery when skin cancer is present and confirmed by biopsy. The cost to you depends on your deductible and coinsurance; the procedure itself typically costs $1,500 to $3,500 before insurance. If your dermatologist suspects skin cancer but has not yet biopsied it, confirm with your insurance whether a biopsy is covered before the appointment, because some plans require it to be done in a specific setting or by a specific provider.

Chemical peels and injectable medications

Chemical peels use acids—glycolic acid, salicylic acid, trichloroacetic acid (TCA), or phenol—to dissolve the outer layers of skin and stimulate collagen remodeling. Light peels affect only the epidermis and cause mild redness; medium peels penetrate the dermis and cause visible peeling and downtime of three to seven days; deep peels use phenol and require significant downtime and healing over weeks. Chemical peels treat acne, sun damage, fine wrinkles, and uneven pigmentation. A single light peel costs $100 to $300; medium peels run $500 to $2,000; deep peels can exceed $3,000. Most insurance does not cover peels unless they are treating a medical condition like severe acne or precancerous lesions.

Injectable medications include corticosteroids injected directly into keloid or hypertrophic scars to flatten them, and botulinum toxin (Botox) or dermal fillers injected for wrinkles or volume loss. Steroid injections for scars are often covered by insurance if the scar is causing functional problems or significant distress. Botox and fillers are typically considered cosmetic and not covered. A single steroid injection into a scar costs $100 to $300 out of pocket; Botox runs $10 to $15 per unit with most people needing 20 to 60 units per session; dermal fillers range from $500 to $2,000 per syringe depending on the product.

How insurance covers advanced dermatology treatments

Insurance coverage depends on whether the treatment is deemed medically necessary or cosmetic. A treatment is usually considered medically necessary if it treats a diagnosed disease, controls symptoms, or prevents complications. Laser treatment for rosacea or precancerous lesions is often covered; laser treatment for wrinkles or age spots is not. Biologic medications for severe psoriasis or eczema are covered once prior treatments have failed; Botox for wrinkles is not.

Your insurance plan also determines whether you need a referral from your primary care doctor or another dermatologist before seeing an advanced dermatology specialist, and whether you can see an out-of-network provider. Some plans cover out-of-network dermatologists at a lower rate; others do not cover them at all. Before scheduling, call your insurance company with the specific procedure code or treatment name and ask whether it is covered, what your out-of-pocket cost will be, and whether a referral or prior authorization is required. Prior authorization means your dermatologist must submit documentation to the insurance company before the procedure, and approval can take one to two weeks.

Finding an advanced dermatology provider

Advanced dermatology is practiced by dermatologists who have completed additional fellowship training beyond their standard dermatology residency. Fellowships typically last one to three years and focus on areas like Mohs surgery, laser and cosmetic dermatology, pediatric dermatology, or dermatopathology. You can search for fellowship-trained dermatologists through the American Academy of Dermatology (AAD) website, which has a "Find a Dermatologist" tool that lets you filter by location and subspecialty.

Many advanced dermatology services are offered at academic medical centers, large dermatology practices with multiple providers, or specialized surgical centers. If your primary dermatologist cannot treat your condition in-office, they will usually refer you to someone who can. If you are looking on your own, check whether the provider is in-network with your insurance and whether they accept your insurance at all—some advanced practices are cash-only or accept only certain plans. Call ahead to ask about wait times; advanced dermatology appointments often have longer waits than standard dermatology because the procedures are more complex and time-intensive.

Frequently Asked Questions

Will my insurance cover biologic medications for my skin condition?

Most insurance plans cover biologic medications for severe inflammatory skin diseases like psoriasis and eczema, but only after you have tried and failed conventional treatments such as topical steroids or oral medications. Your dermatologist will need to document this treatment history and submit it for prior authorization. Approval typically takes one to two weeks.

How many laser sessions do I need to see results?

Results depend on the condition and the laser used. Rosacea and broken blood vessels may improve after one or two sessions; acne scars and pigmentation usually require three to six sessions; hair removal typically needs six to eight sessions. Sessions are spaced four to six weeks apart to allow skin to heal between treatments.

Is Mohs surgery more expensive than regular skin cancer removal?

Mohs surgery costs more upfront—typically $1,500 to $3,500 before insurance compared to $500 to $1,500 for standard excision—but the higher cure rate and tissue preservation often make it worth the cost, especially on the face. Insurance usually covers both procedures the same way once skin cancer is confirmed.

Can I get a chemical peel if I have darker skin?

Light and medium chemical peels can be used on darker skin tones, but deeper peels carry a higher risk of post-inflammatory hyperpigmentation (darkening) or hypopigmentation (lightening). A dermatologist experienced in treating darker skin should assess your skin type and recommend the safest depth and acid concentration for you.

What happens if my insurance denies coverage for a treatment my dermatologist recommends?

Ask your dermatologist to submit an appeal with additional clinical documentation explaining why the treatment is medically necessary. If the appeal is denied, you can pay out of pocket, ask about payment plans, or explore whether a different treatment your insurance does cover might help. Some manufacturers of biologic medications offer copay information programs if cost is a barrier.
