Blisters on exposed skin are small, fluid-filled sacs that form on the outer layer of the skin, typically in response to damage or irritation. They appear as raised areas filled with clear or slightly yellowish fluid and can develop on various parts of the body, including the hands, feet, and areas frequently exposed to friction or pressure. Blisters are often a protective response by the skin to prevent further injury and to promote healing of the underlying tissues. The primary causes of blisters include friction, such as that from ill-fitting shoes or repetitive rubbing, which can lead to the formation of blisters on the feet or hands. Sunburn, caused by overexposure to ultraviolet (UV) radiation, can also lead to blistering as a result of severe skin damage. Additionally, chemical burns, allergic reactions, or infections, such as herpes simplex virus or impetigo, can cause blisters.
Treatment for blisters involves managing the underlying cause and ensuring the blisters are protected to prevent infection. For blisters caused by friction, it is important to avoid further irritation by using protective padding or switching to properly fitting shoes or gloves. Keeping the blister clean and covered with a sterile bandage can help prevent infection. If a blister bursts, it should be cleaned with mild soap and water, and a non-stick bandage should be applied. In cases of sunburn blisters, using soothing lotions or aloe vera gel can help relieve discomfort and promote healing. For blisters resulting from burns or infections, medical treatment may be required, including topical or oral antibiotics. If blisters are recurrent or persistent, or if they are accompanied by severe pain, signs of infection, or other concerning symptoms, it is important to seek medical advice to determine the appropriate treatment and address any underlying issues.
