Doctor examining mans face for cosmetic treatment at clinic


Dermatology is the medical science that deals with skin and the issues related to it. While many of us pay the utmost attention to beauty products, clothing, jewellery, and everything else that enhances our appearance, the fundamental rule of taking care of our skin, takes a backfoot.

Our skin reflects what we are and how we live. Good skin results from the correct nutrition, proper hydration, adequate physical exercise, and most importantly, a stress-free mind. If there is something wrong with these life-basics, the skin shows them first!

While we make sure to get our vitals checked annually, we often forget to keep skin specialists in mind. No matter how healthy a lifestyle we follow, getting a routine skin exam is equally important. Unfortunately, a dermatologist only makes it through our checklist if things get out of hand.

When to Visit a Dermatologist?

Ideally, in case of mild skin problems like occasional acne, minor rashes, bug or insect bites, dandruff, hives (mostly reactions to allergies), warts, minor fungal infections, and other scalp issues, rosacea, nail infections, burns, and minor injuries, one can consult a primary care physician.

However, when the conditions start to spread systemically, affecting a major part of the body, it is advisable to consult a dermatologist atSkin Rash Treatment Hospital Coimbatore. Any skinproblem that spreads to more than 10% of the body and causes secondary issues like fever, malaise, body ache, muscle pain, swallowing issues, breathlessness, or sleeping issues deserves expert opinions from the best skin doctors.

If the skin shows any new sign that might appear abnormal, it is advisable to consult a dermatologist. Multiple issues may cause inflammatory reactions or otherwise and manifest themselves on the skin. Some of these severe conditions include –


An autoimmune condition that makes the body’s immune system attack itself and causes inflammation and pain. Apart from harming the internal organs, it also causes reddish ring-like patches all over the skin, especially in the cheeks and nose. These rashes do not hurt but are an indicator, nonetheless.


A form of skin cancer that causes abnormally shaped moles to appear on the body. Women are more prone to melanoma. If you notice any such moles with ragged edges and rough surfaces, uneven colors that have no particular shape but start appearing off late, rush to a dermatologist.


Another autoimmune disorder that causes redness and rashes is making patches of skin dry and itchy. While some patches do not itch as much, others can be really itchy. There are different kinds of psoriasis depending on the areas it affects and the type of rashes it causes. If the scalp gets affected, there is excess hair-fall and the appearance of bald spots.


It is a condition commonly found in neonates and young children that also continues through adulthood. It is also referred to as dermatitis. It manifests as rashes all over the scalp, face, neck, wrists, elbows, ankles, or legs (commonly behind the knees). Their anatomical location determines their specific type.

The rashes are constantly itchy and may vary in nature, becoming bumpy or thickened in parts, often converting into pus-filled blisters due to continuous itching. If these blisters rupture and open, it also leads to bacterial infection that further complicates things. Eczema causes permanently itchy and dry skin in adults if not taken care of on time.


Abnormal pigmentation of the skin leads to dark and lighter patches all along the skin or specific areas. Though there is no proven cure for the condition, you can consult your dermatologist for any special treatment measure he might suggest.

COVID-19 and Dermatology

Due to the ongoing COVID-19 pandemic, there have been multiple instances of skin infections and abnormalities that both patients and healthcare workers have reported. These conditions are either due to the virus itself or due to excessive use of personal protective equipment (PPE), which doctors, healthcare workers, crematorium staff, and other frontline healthcare workers have to wear for longer hours.

Healthcare workers and frontline workers have to don PPE such as the N95 mask, gloves, goggles, and gowns, which cause skin issues due to the chemical nature of this equipment that leads to pressure injuries and contact dermatitis. The most commonly affected areas include the hands (15%–85%) and face (12%–87%). Less frequently affected areas include the legs, trunks, and overall body.

The most commonly reported conditions include –

  • erythema
  • papule/edema
  • exudation/crust formation on the skin
  • scratches, fissures, blisters
  • lichenification (a condition where the skin becomes rubbery or leathery due to constant scratching or rubbing)

The most common skin conditions faced by COVID-19 patients include different forms of maculopapular exanthema, urticarial and acral lesions, vesicular eruptions, livedo reticularis, and erythema multiforme-like lesions. The urticaria and maculopapular lesions are more common. Some of these lesions have been observed in asymptomatic or mild cases, while some have been affecting hospitalised patients. They are more common in the upper body. A condition called ‘COVID toes’ affects the lower body (toes) in the form of pernio or chilblains, or frostbite.

Rashes and local inflammation are common adverse effects of patients treated with drugs like remdesivir, favipiravir, azithromycin, hydroxychloroquine, oseltamivir, and so on. There are minor adverse effects for people getting vaccinated, including erythema and reddening, and swelling of the vaccination spot.

Patients under medical supervision get treated for these conditions alongside COVID-19 treatment. However, if any condition persists for long, you need to consult a dermatologist!
