Your skin is your body’s largest organ, protecting you from cold, heat, germs, and dangerous substances. It also serves as a window into your overall health.


When you have a rash that won’t go away or a mole that appears suspicious, your dermatologist is the person to turn to for help. Dermatologists perform various duties ranging from screenings for precancerous skin lesions to treating stubborn acne. Visit to learn more.

The skin is the largest organ of the human body, with important functions that include regulation of temperature, protection of bodily tissue, assisting in vitamin production and immune defence, and facilitation of sensation. But the skin is also prone to a wide variety of conditions and problems, from acne and psoriasis to warts and nail infections. Because of this, it’s essential to visit a dermatologist when you have a skincare problem.

Dermatologists are highly trained in recognizing and treating a wide range of skin issues. They understand that a single condition can significantly affect your quality of life. In addition, a skin issue can sometimes be a sign of an underlying health problem such as heart disease or diabetes.

During your first visit to the dermatologist, they’ll discuss your medical history and any specific symptoms you have. Then, they’ll examine your skin from your scalp to your soles, looking for anything unusual or out of the ordinary. If they detect something, they’ll test it with blood work, allergy testing, a scraping or a biopsy.

If they confirm the diagnosis, they’ll provide treatment recommendations. This may include prescription medications, creams or ointments. In some cases, they may suggest phototherapy or biologic therapy.

They can also treat nail and hair problems, including fungal infections, ingrown nails, ringworm and psoriasis of the nails. And, they can use lasers and other treatments to remove warts. They can also help with vitiligo, where patches of the skin lose their pigmentation and become lighter in colour. And, they can manage eczema, which causes dry, flaky, itchy and painful patches of skin to appear on the knees, elbows, hands, face, scalp or feet.

They Treat Acne

As the body’s largest organ, the skin carries out many important tasks: It protects us from germs; it repels water and covers blood vessels, nerves and internal organs. So, if you have an issue with your skin that affects the way you look or feels, it is wise to consult a specialist. A dermatologist is a medical doctor who has been trained to diagnose and treat disorders that affect the skin, hair and nails. They will examine you, order lab tests and then treat your condition with medication or a procedure.

Acne is one of the most common reasons people see a dermatologist. The condition occurs when the skin’s oil (sebaceous) glands or hair follicles become blocked with oils, dead cells and bacteria. When this happens, inflammation and irritation result. If left untreated, the condition can lead to dark spots and permanent scars. While acne is usually associated with teenagers, the condition can persist into adulthood and negatively impact a person’s self-esteem.

A dermatologist can prescribe a combination of medications that can help control acne or remove acne scars. This treatment may include a face wash, a cream or lotion and an antibiotic or hormone suppression tablet. They can also prescribe a powerful drug called retinoids which can completely cure a significant percentage of patients.

Dermatologists can also perform a number of surgical procedures. They can remove growths like warts, skin tags and lesions. They can also perform cryosurgery which involves the use of extreme cold to freeze and destroy tissue. They can perform excision surgery to remove moles or skin cancers and can even use a technique called Mohs surgery which removes the cancerous cells layer by layer.

In addition to these surgeries, a dermatologist can provide other cosmetic treatments including laser and light-based therapies. These can be used to reduce redness and discoloration of the skin caused by acne. They can also be used to diminish the appearance of spider veins and varicose veins.

They Perform Cosmetic Procedures

Dermatologists are trained to recognize the skin’s many structures, including nerve endings, hair follicles, pores and blood vessels. The dermatologist may also do a full-body skin check to look for lesions, moles and growths that can turn into cancer. They can then treat the spots with medication or surgery, and remove them if needed. In addition to their medical training, they are often skilled at performing cosmetic procedures to improve the appearance of the skin.

A dermatologist can perform laser treatment that corrects sun damage, aging skin, wrinkles and acne scarring. This type of laser treatment uses powerful light beams that cause controlled injury to the skin, encouraging healing and leaving it looking more youthful. A dermatologist can also do microneedling, which is a procedure that creates thousands of tiny needle-like wounds in the skin. This stimulates collagen production and encourages the skin to appear more youthful and smooth. A dermatologist can also do chemical peels, which are a form of exfoliation that helps to reduce the appearance of fine lines and wrinkles.

The most common cosmetic dermatology procedures are injections of Botox and fillers like collagen and fat. They can also remove dilated superficial veins, known as spider veins, with a technique called sclerotherapy, which involves injecting the affected area with a foam or a special solution that causes the lining of the vein to close over. A dermatologist can also remove excess body fat by using a technique called tumescent liposuction, which is a non-invasive way to remove fat cells from the body.

Cosmetic procedures can boost self-esteem and give people confidence that they are achieving a more positive image. They can also help those who are socially isolated because of their appearance feel more comfortable in society. It is important to choose a physician who has been trained to perform the chosen procedure according to national and state standards. This will ensure that the patient is getting the best results possible.

While any health care professional can perform a cosmetic procedure, choosing the right one is essential. Patients should always choose a physician who has completed an approved three-year dermatology residency, and who is also board certified in their specialty. Consumers who are interested in cosmetic procedures should ask physicians to provide them with proof of their training before undergoing any treatments.

They Perform Surgical Procedures

Dermatologists are not only trained in treating diseases of the skin, hair and nails, but also in surgically removing them. The skin is the body’s largest organ, and it protects us from heat, cold, germs and dangerous substances. The skin is also a good indicator of our overall health — signs of heart disease, diabetes and other serious conditions can show up on the surface. Because of this, dermatologists often recognize these symptoms before other medical professionals.

Because of this, dermatologists perform various surgical procedures on the skin to remove blemishes and diseases that affect the appearance and function of the tissue. Thanks to research breakthroughs and surgical instrumentation innovations, the majority of dermatologic surgeries are minimally invasive, requiring only local or regional anesthesia for optimal patient safety and comfort.

A few of the most common types of surgical procedures performed by dermatologists include:

Mohs Surgery

Mohs surgery is a special type of skin cancer procedure that utilizes microscopic evaluation to precisely remove cancerous growths and their surrounding margins. This ensures that no cancerous cells remain, reducing the risk of future growth and metastasis (spread of cancer from one area to another). Mohs surgeons are specially trained in this highly specialized technique.


Cryosurgery is a non-invasive way to remove skin tags, age spots and early-stage basal and squamous cell carcinomas. It uses liquid nitrogen to freeze the growth and destroy the tissue, and local anesthesia is usually not needed.

Electrodesiccation and Curettage

During this procedure, the dermatologist will numb the area with a small injection of anesthetic, then use a sharp tool to scrape away the growth. An electrosurgical unit may then be used to stop any bleeding, and the doctor will cut a thin layer of tissue that will later be processed and examined under a microscope.

Nail surgery

Dermatologists can remove fungus, parasites and warts from the nails using a variety of techniques. They can also reconstruct the nail if necessary. Before having any nail surgery, it’s important to tell the doctor if you have a history of severe allergies or sensitivities to local anesthetics, latex and tape adhesives. It’s also important to discuss your medical history and current medications, including herbs and supplements, with the doctor.
