Blaar

Blaar is the Dutch word for blister, a small bubble on the skin filled with fluid. Blisters occur when the skin is damaged by friction, heat, or chemical exposure, causing the epidermal layer to separate from the underlying dermis and a fluid-filled cavity to form.

Most blisters contain clear, watery fluid called serum. Hemorrhagic blisters contain blood and are darker. If infected, the blister may become cloudy, and the surrounding skin may appear red and warm.

Causes and risk factors include repeated rubbing from ill-fitting footwear or equipment, burns from hot liquids or surfaces, sunburn, chemical irritants, and certain skin conditions. People with diabetes or immune disorders may experience more severe complications.

Symptoms commonly include a raised, tender or painful bump that may itch. An intact blister is usually painless but sensitive to pressure. When the blister breaks, the area may ooze, crust over, and be at higher risk of infection.

Treatment focuses on protecting the area and preventing infection. For intact blisters, cover with a sterile, nonstick bandage and avoid bursting. If the blister breaks, clean gently with soap and water, apply an antiseptic and a clean dressing. Seek medical advice for large, persistent, or infected blisters.

Prevention involves reducing friction and protecting the skin, such as wearing well-fitting footwear, using padding in high-friction areas, keeping skin moisturized, and gradually increasing activity to build tolerance.
