What Is a Skin Doctor

Find out what a skin doctor is, what conditions they treat, and how they help diagnose and manage skin, hair and nail problems professionally.

A skin doctor is commonly known as a dermatologist—a medical specialist who diagnoses, treats and manages conditions affecting the skin, hair, and nails. They’re trained to deal with everything from acne, eczema and psoriasis to more serious concerns like skin cancer. In some contexts, people may also use terms like cosmetic dermatologist or aesthetic practitioner, but the true definition of a skin doctor refers to a medically qualified expert in dermatology.

Dermatologists complete years of medical training before specialising in skin health, and they can offer both medical and cosmetic care depending on the issue at hand.

What Do Skin Doctors Treat?

Skin doctors deal with a wide range of concerns—not just cosmetic issues. Some of the most common conditions they treat include:

  • Acne, blackheads, and breakouts

  • Rosacea, redness and inflammation

  • Eczema and other forms of dermatitis

  • Psoriasis and autoimmune skin diseases

  • Warts, moles and cysts

  • Skin infections such as fungal or bacterial issues

  • Hair loss and scalp disorders

  • Nail disorders, including discolouration or thickening

  • Skin cancer, including mole checks and biopsies

  • Pigmentation problems, like melasma or vitiligo

They also perform minor procedures like skin tag removal, mole excision, cryotherapy and biopsies, and can advise on skincare routines and treatments based on your skin type or condition.

How Are They Different From Beauticians or Aestheticians?

Unlike beauticians or skincare therapists, a dermatologist is a qualified medical doctor. They’re able to diagnose complex skin conditions, prescribe medication, and carry out clinical procedures. While beauticians and aestheticians may offer facials, peels and product recommendations, they don’t have the authority to treat serious or chronic conditions or prescribe prescription-strength treatments.

If your skin concern is persistent, painful, or affects your overall health, a skin doctor is the right person to see.

Can Skin Doctors Help With Cosmetic Concerns?

Yes. Many dermatologists offer cosmetic treatments such as:

  • Anti-wrinkle injections and fillers

  • Chemical peels

  • Laser treatments for hair removal or pigmentation

  • Microneedling and skin resurfacing

These services are provided in a medical context with a focus on safety and skin health, especially if you have an underlying condition that could affect how your skin reacts.

When Should You See a Skin Doctor?

You should consider seeing a dermatologist if you have a skin condition that hasn’t responded to over-the-counter products, ou experience chronic or recurring rashes, itchiness or irritation, you notice changes in a mole’s shape, colour or size, you have unexplained hair loss or nail changes or You want a medical opinion before starting strong treatments or cosmetic procedures

Early diagnosis often leads to better outcomes, especially for issues like skin cancer or autoimmune skin diseases.
