What is a lesion on the skin? Causes of skin lesions

Acne

Whiteheads, blackheads, pimples, and cysts are all forms of acne.

It may be innocuous for some, but for others, it might lead to scars or poor self-esteem.

Acne arises when the pores in the skin are blocked with dead skin cells and the skin’s natural oil, called sebum.

Bacteria may also seep into the plugged pore, inflaming the sores.

OTC medications containing benzoyl peroxide or salicylic acid may be useful for those with minor acne. You should see visible results between 4-8 weeks of usage.

If acne is more severe or if OTC medications do not help, a person should contact a dermatologist.

Actinic keratosis

Actinic keratosis is induced by exposure to ultraviolet radiation and shows up as thick, scaly crusts on the skin.

It normally doesn’t develop until later in life due to prolonged exposure to sunlight.

Actinic keratosis is frequently easier to feel than see owing to its scaly raised surface.

Over time, it may become hard and wart-like.

Treatment for actinic keratosis might be by freezing (cryosurgery), scraping (curettage), or laser ablation.

There are various topical creams include fluorouracil, diclofenac, and imiquimod for treating actinic keratosis.

Blisters

Because they are filled with fluid, blisters make your skin look a little different.

Blisters can be caused by friction (for example, when you walk, your shoes rub against each other).

They can also be caused by a burn, skin disorder, or allergic reaction.

It is possible to treat most blisters with a bandage at home, but not all of them.

Try not to pop blisters, and don’t put more pressure on the area where they’re already there, either.

Make sure to clean the area and cover it with a sterile bandage until it’s healed.

If you see pus, fever, or red hot skin around the blister, then see a doctor.

Cold sores

A cold sore is a blister that is red, painful, and filled with fluid. It usually appears near the mouth or lips.

In addition to genital lesions, herpes simplex 1 (HSV-1) and herpes simplex 2 (HSV-2) cause these types of oral lesions.

Before a cold sore is visible, the area where it is will often tingle or burn, and this can be a sign that something is wrong.

These blisters can be on their own or in groups, and they leak clear yellow fluid before they become crusty.

Blisters may come back due to stress, menstruation, illness, or sun exposure.

Cellulitis

Cellulitis is a skin illness caused by bacteria or fungus penetrating the skin.

As a result, the skin becomes inflamed, uncomfortable, and prone to fluid leakage.

To put it another way, it’s scalding hot to the touch and may make you feel ill.

Most instances may be treated on an outpatient basis with a course of antibiotics if found early.

See a doctor if it gets too severe.

Eczema

Allergic eczema makes the skin itchy, red, scaly, or raw. It can also make the skin very dry and itchy.

People with eczema should avoid anything that makes it worse. Bath and moisturize every day.
