Blisters Explained

I'm an aspiring dermatologist and cosmetic scientist

Blistering happens when fluid collects between layers of the skin after damage from friction, burns, allergies, infections, or irritation. The blister acts like a protective cushion while the skin underneath heals. Some blisters are painful, itchy, or filled with clear fluid. Popping them can increase the risk of infection. In some skin diseases, blistering occurs because the immune system attacks healthy skin cells, weakening the skin barrier and causing separation between skin layers.
