What are the most common procedures performed by dermatologists in their clinics?

Common In-Office Dermatological Procedures

Dermatologists are medical doctors specializing in the health of the skin, hair, and nails. Their clinical practice encompasses both medical and surgical care, addressing conditions ranging from acne and skin cancer to cosmetic concerns. While consultations and prescriptions are a core part of their work, many dermatologists perform a variety of in-office procedures. These interventions are typically chosen based on a patient's specific diagnosis and treatment goals, following a thorough evaluation. According to data from professional dermatological societies and practice surveys, several procedures are performed with high frequency in clinics worldwide.

1. Skin Cancer Screenings and Biopsies

The detection and treatment of skin cancer is a fundamental aspect of dermatology. The most common procedure in this category is the skin biopsy. When a dermatologist identifies a suspicious mole, growth, or lesion, a biopsy is performed to obtain a tissue sample for laboratory analysis. This is a critical diagnostic step to determine if a lesion is cancerous (such as melanoma, basal cell carcinoma, or squamous cell carcinoma) or benign. Several biopsy techniques are used, including shave, punch, and excisional biopsies, chosen based on the lesion's characteristics.

2. Cryotherapy

Cryotherapy involves the application of extreme cold, usually via liquid nitrogen, to destroy abnormal tissue. It is a quick, common, and effective treatment for a variety of benign and pre-cancerous skin conditions. Dermatologists frequently use cryotherapy to treat:

• Actinic keratoses (pre-cancerous sun spots)
• Common warts
• Seborrheic keratoses (benign, wart-like growths)
• Molluscum contagiosum

The procedure causes the targeted cells to freeze and die, often resulting in a blister that heals over the following days to weeks.

3. Excision of Skin Lesions

This surgical procedure involves the complete removal of a skin lesion, often for both diagnostic and therapeutic purposes. Using local anesthesia, the dermatologist cuts out the entire lesion along with a small margin of normal-looking skin. The wound is then closed with stitches. Excisions are commonly performed for confirmed skin cancers, suspicious moles, cysts, lipomas, and other growths. The removed tissue is almost always sent to a pathology lab for analysis to confirm the diagnosis and ensure complete removal, especially in cases of malignancy.

4. Electrosurgery and Cauterization

Electrosurgery uses a high-frequency electrical current to cut, destroy, or coagulate tissue. A common form is electrodesiccation and curettage (ED&C), often used to treat basal cell and squamous cell carcinomas, as well as benign growths. Cauterization, which uses heat to stop bleeding or remove small lesions, is also frequently employed during other procedures like biopsies and excisions to achieve hemostasis (control of bleeding).

5. Injections

Dermatologists administer a range of therapeutic injections. Common examples include:

• Corticosteroid injections: Used to reduce inflammation and promote healing in conditions like cystic acne, alopecia areata, hypertrophic scars, and keloids.
• Botulinum toxin injections: While known cosmetically for reducing wrinkles, these are also used medically to treat conditions such as hyperhidrosis (excessive sweating), chronic migraines, and certain muscle disorders.
• Filler injections: Used to restore volume for both cosmetic enhancement and medical reconstruction (e.g., after skin cancer surgery).

6. Light and Laser Therapies

Various light-based devices are staples in the dermatology clinic. These treatments use specific wavelengths of light to target precise structures in the skin. Common applications include:

• Pulsed dye laser (PDL): The gold standard treatment for port-wine stain birthmarks and rosacea-related redness and visible blood vessels.
• Fractional lasers: Used for skin resurfacing to improve the appearance of acne scars, fine lines, and sun damage.
• Intense Pulsed Light (IPL): Often used to treat sun spots, freckles, and vascular lesions.
• Photodynamic therapy (PDT): A treatment for widespread actinic keratoses and some superficial skin cancers, involving a light-sensitizing agent and a specific light source.

7. Chemical Peels

Chemical peels involve the application of a solution to the skin, causing controlled exfoliation and eventual peeling. This reveals newer, smoother skin underneath. Dermatologists use peels of varying depths (superficial, medium, deep) to treat a spectrum of concerns, including:

• Acne and acne scars
• Sun damage and uneven pigmentation
• Fine lines and wrinkles
• Dull skin texture

The choice of chemical agent (such as glycolic, salicylic, trichloroacetic, or phenol acid) depends on the patient's skin type and treatment goals.

Consulting a Board-Certified Dermatologist

The procedures listed above represent a core set of tools dermatologists use to manage skin health. It is important to understand that the suitability of any procedure depends entirely on an individual's specific condition, medical history, and skin type. A board-certified dermatologist can provide a proper diagnosis and discuss all appropriate treatment options, including potential benefits, risks, and expected outcomes.
