What is dermatology, and what is a dermatologist?
Dermatology is the study, research, diagnosis, and management of any health condition affecting the skin, hair, nails, and membranes. A dermatologist is a healthcare practitioner who specializes in this field of medicine. The skin is the largest organ in your body, serving as a barrier protecting internal organs from injury and germs. It is also a good indicator of your body's overall health, making dermatology essential in diagnosing and treating many health conditions.
A dermatologist may provide medical or surgical treatment and perform various procedures, most of which are cosmetic. Some of these procedures include:
- Cosmetic filler injections
- Hair removal or transplantation
- Intralesional treatment
- Laser therapy
- Photodynamic therapy
- Phototherapy
- Tattoo removal
- Tumescent liposuction
- Radiation therapy
- Vitiligo surgery
Education and training of dermatologists
An aspirant in dermatology should have a bachelor's degree in biology, chemistry, or a pre-med program. They must also take as many science and calculus courses as possible in addition to psychology, anatomy, and physiology subjects. The next step involves clearing the Medical College Admission Test (MCAT), a 7.5-hour examination that covers biology, chemistry, psychology, and critical thinking. Following this, aspirants can apply to a medical school recognized by the Association of American Medical Colleges (AAMC).
Students complete the first two United States Medical Licensing Exam (USMLE) examination levels during medical school. They also undertake internships and residency programs recognized by the Accreditation Council for Graduate Medical Education (ACGME). Some aspirants may pursue additional dermatopathology, Mohs surgery, or pediatric dermatology fellowships.
Following this, dermatologists take the third and final USMLE exam to earn a medical license. Lastly, after completing their educational, residency, fellowship, and licensure requirements, dermatologists apply for board certification to the American Board of Dermatology or the American Osteopathic Board of Dermatology.
Difference between a dermatologist and an esthetician
Estheticians are not doctors. They cannot diagnose skin conditions or prescribe medications. They can only assist with treatments that impact the appearance of your skin.
The following are some procedures an esthetician typically performs:
- Exfoliating (scrubbing) the skin
- Teaching how to conceal scars with makeup
- Providing acne treatments
- Airbrush tanning
- Recommending skin care products
- Waxing
On the other hand, dermatologists can treat thousands of skin, hair, and nail conditions. Among the most common conditions they treat are:
- Acne: Depending on the severity of your condition, a dermatologist can treat acne with topical treatments, chemical peels, medication lasers, or other light therapies or by removing large cysts.
- Skin cancer: Skin cancer can originate anywhere on the body. A dermatologist can eliminate cancer cells and monitor you to ensure they do not reappear.
- Dermatitis is a group of skin conditions that cause swelling and irritation. Eczema, cradle cap, and allergic reactions are a few examples.
- Infections: Viruses, fungi, bacteria, and parasites can enter your skin and cause various skin infections. Dermatologists can assist in determining the source of the disease and prescribe the appropriate treatment.
- Hair loss: Hereditary baldness, stress, illness, and hormonal changes can all contribute to hair loss. Dermatologists can help identify the underlying cause and treat it.
- Nail issues: Dermatologists treat common nail issues such as spots, discoloration, and separation.
Common skin conditions
Various health conditions and lifestyle choices can trigger certain skin disorders. Here are some common ones:
Acne develops when blocked skin follicles form a plug of oil, bacteria, and dead skin cells, leading to swelling.
Alopecia areata attacks the hair follicles, which produce hair. Hair may start to fall out in small, round patches.
Atopic dermatitis is a condition that causes intense itching. Scratching results in redness, swelling, cracking, oozing clear fluid, crusting, and scaling.
Epidermolysis bullosa refers to a group of diseases that cause painful skin blisters. If the blisters become infected, they can lead to complications.
- Hidradenitis Suppurativa (HS)
Hidradenitis suppurativa, also called acne inversa, is a chronic, noncontagious inflammatory condition marked by pimple-like bumps or boils, along with tunnels or tracts on and under the skin.
Ichthyosis is a disorder that leads to dry, thickened skin with a texture and appearance similar to fish scales.
Pachyonychia congenita is a rare condition that causes thick nails, painful calluses on the soles of the feet, and other symptoms.
Pemphigus is an autoimmune condition in which the immune system attacks healthy cells in the upper layer of the skin, forming blisters.
Psoriasis causes red, scaly skin that may feel swollen, painful, or hot.
Raynaud's phenomenon affects blood vessels and limits blood flow to the hands and feet for periods of time.
Rosacea is a long-term condition that causes facial redness and pimples. It can also lead to skin thickening and eye issues.
Scleroderma leads to areas of tight, hardened skin and may also damage blood vessels and internal organs.
Vitiligo results in patches of skin to lose color when pigment-producing cells are destroyed.
Causes of skin disorders
Common causes of skin disorders include:
- bacteria trapped in hair follicles and pores
- viruses
- parasites, fungi, or other microbes living on the skin
- a weak immune system
- contact with allergens, irritants, or another person's infected skin
- genetic factors
- illnesses that affect the thyroid, immune system, kidneys, or other body systems
Types of dermatology therapies
There are various dermatological therapies to treat skin disorders. These include:
- Radiotherapy
- Topical medications
- Surgery
- Phototherapy
- Laser therapy
- Immunotherapy
- Systemic medications
- Dermatohistopathology
- Photodynamic therapy
Each of these therapies serves a specific purpose in treating particular dermatological conditions. The most common type of treatment is topical agents, applied directly to the affected area to achieve the desired effect.
Essential dermatologist-approved tips for healthy skin
Dermatologists recommend the following practices to keep the skin in good condition:
- Use sunscreen daily: Protecting your skin with sunscreen is crucial. When used correctly, sunscreen shields your skin against UV radiation, which can cause sunburns, skin cancer, and signs of early aging, such as wrinkles and age spots. Apply a water-resistant, broad-spectrum sunscreen and reapply every two hours or after swimming or sweating. For convenience, consider using a moisturizer that includes sunscreen to simplify your skincare routine.
- Refrain from touching your face: When you touch your face, you can transfer oil, bacteria, and debris from your hands. Refrain from touching your skin and resist the urge to pick, squeeze, or pop pimples, which can lead to scarring.
- Simplify your skincare regimen: Less is often more when it comes to skincare. Overusing products, especially anti-aging treatments, can irritate the skin. Instead, focus on essentials such as a gentle cleanser, sunscreen, and moisturizer. Establish and stick to morning and evening routines that suit your skin type.
- Take care of your lips: Before going outside, use lipstick or lip balm with 30 or more SPF. If your lips appear dry or cracked, apply petroleum jelly for extra hydration.
- Examine your skin frequently: In the United States, skin cancer is the most common, affecting one out of every five Americans. Moreover, melanoma, the deadliest type of skin cancer, claims the lives of roughly 20 Americans each day. However, skin cancer, including melanoma, is highly treatable if detected early. Regularly check your skin for new spots that differ from others on your body or moles that itch, bleed, or change color. Schedule a consultation with a dermatologist near you if you find any suspicious areas.
What is psoriasis and its symptoms?
A chronic skin disorder called psoriasis results in scaly, itchy regions on the skin, often on the knees, elbows, trunk, and scalp.
Psoriasis stems from an immune system issue that causes accelerated skin cell growth. This quick cell turnover leads to dry, scaly patches in the prevalent form known as plaque psoriasis.
It's still unknown what causes psoriasis specifically, but it is attributed to an immune system anomaly where immune cells mistakenly target healthy skin cells. Genetics and environmental factors can contribute to this disease, and it is essential to note that psoriasis is not contagious.
Some of the common indicators of psoriasis are:
- Patchy rashes with diverse appearances from one individual to another, from dandruff-like scaling to extensive eruptions across the body.
- Rashes can differ in color, appearing as shades of purple with a gray scale on brown or black skin or pink or red with silver scales on white skin.
- Small scaling spots are often seen in kids.
- Dry, cracked skin prone to bleeding
- Sensations of itching, burning, or soreness
- Cyclic rashes, intensifying for several weeks or months before receding
People prone to psoriasis can stay symptom-free for years until an environmental factor sets off the disease. Common triggers for psoriasis include:
- Infections, like strep throat or skin infections.
- Weather conditions, particularly cold and dry climates.
- Skin injuries, including cuts, scrapes, bug bites, or severe sunburn.
- Smoking and exposure to secondhand smoke.
- Excessive alcohol consumption.
- Specific medications include lithium, high blood pressure, and antimalarial drugs.
- Abrupt discontinuation of oral or injected corticosteroids.
This disease, with no known cure, is quite common. It can cause pain, disrupt sleep, and affect concentration. Psoriasis typically alternates between flare-ups lasting weeks or months.
