What is the difference between a skin doctor and a dermatologist?

A skin doctor and a dermatologist are both medical professionals who treat skin conditions, but there are some key differences between them when it comes to their training, expertise, and scope of practice. Understanding these differences can help you determine which type of specialist is best suited to treat your particular skin concern.

Skin Doctor

A skin doctor is a broad term that can refer to any physician who treats skin diseases and disorders. This includes:

• Primary care physicians – A primary care doctor like a family medicine doctor or general practitioner can provide basic skin care, diagnose common conditions like acne and eczema, and refer patients to a dermatologist for more complex skin issues.

• Allergists/immunologists – Allergists treat skin conditions related to allergies and immune system disorders like hives, eczema, and psoriasis.

• Plastic surgeons – Plastic surgeons deal with skin issues related to cosmetic procedures as well as serious skin cancers and reconstruction after major trauma.

The level of skin care training and expertise can vary widely among skin doctors who are not specialized dermatologists. They provide generalized skin care and treatment, especially for minor acute issues like rashes, insect bites, and skin infections. For chronic, complex, or undiagnosed skin problems, they will usually refer you to a dermatologist.

Dermatologist

A dermatologist is a medical doctor who has undergone several additional years of specialized training and education in treating diseases of the skin, hair, and nails after finishing medical school.

To become a dermatologist, a physician must:

• Complete medical school and earn an M.D. or D.O. degree (4 years)
• Complete a residency program in dermatology (3-4 years)
• Pass licensing exams and become board certified in dermatology

This extensive training equips dermatologists to provide expert diagnosis and treatment for a wide range of skin conditions, including:

• Skin cancer – melanoma, basal cell carcinoma, squamous cell carcinoma
• Inflammatory skin diseases – psoriasis, eczema, rosacea
• Infections – fungal, bacterial, viral
• Immune system disorders – lupus, dermatomyositis
• Hair and nail disorders – alopecia, ingrown nails
• Genetic skin disorders
• Cosmetic concerns – acne scars, sun damage, aging skin

In addition to medical expertise, dermatologists are trained in minor surgical procedures like skin biopsies and cryosurgery. Many also provide cosmetic treatments such as Botox, fillers, and laser skin resurfacing.

Key Differences

Training and qualifications

• Skin doctors have an M.D. or D.O. but no specialized training in dermatology.
• Dermatologists complete medical school plus a 3-4 year residency in dermatology.

Scope of practice

• Skin doctors treat common, minor skin conditions and infections.
• Dermatologists treat complex skin diseases, perform surgeries, and provide cosmetic treatments.

Expertise

• Skin doctors have generalized medical knowledge.
• Dermatologists have specialized expertise in complex skin diseases and pathology.

Diagnostics

• Skin doctors can perform a basic physical exam.
• Dermatologists have an in-depth understanding of skin pathology and use diagnostic tests.

Treatment approach

• Skin doctors take a generalized approach to skin care.
• Dermatologists create customized treatment plans and follow up long-term.

When to See a Dermatologist

For serious or chronic skin conditions, it is best to see a dermatologist who has the specialized training to provide an accurate diagnosis and effective treatment plan. Examples include:

• Rashes, growths, moles that are changing or won‘t go away
• Skin cancer screening
• Chronic issues like psoriasis, eczema, acne
• Hair loss or nail disorders
• Cosmetic concerns like wrinkles, scarring, skin discoloration
• Full body skin exam/mole screening

Conclusion

While skin doctors can treat basic skin problems, dermatologists have the advanced expertise, diagnostics, and treatments to manage complex and chronic skin diseases. Their years of specialized training prepares them to provide more complete skin care. If your skin issue is not improving with basic treatment or you need a expert diagnosis, seeing a dermatologist is highly recommended.
