A blister is a small-sized vesicle filled with fluid that forms amidst the upper skin layer. A blister that forms as part of a skin rash might be miniature in size or grow large enough. These blisters are often round-shaped and filled with a serous fluid that might seep out to form a yellowish crust.
Contact dermatitis is a skin rash that arises if the skin was exposed to substances that trigger irritation or an allergic reaction.
The skin rash is usually itchy and red with defined borders. The blisters might develop together with the rash.
The known chemical irritants include tanning agents utilized in footwear and nail polish removers. In some cases, even antibiotics and fragrances used in deodorants and hand lotions are also culprits.
Impetigo is a bacterial skin rash that is prevalent among children but can also affect adults. The skin condition is triggered by the streptococcus or staphylococcus bacteria. It usually develops where there is a break in the skin and results to a rash comprised of small-sized blisters filled with yellowish fluid that rupture to reveal a reddened base.
Can poison ivy trigger a blister skin rash?
Being exposed to poison ivy can cause allergic contact dermatitis. This is due to the presence of urushiol in the plant that binds to the skin upon exposure.
The rash manifests in 24-48 hours. It initially appears as a reddened and swollen rash and small-sized blisters later form. These blisters are excessively itchy but it is vital to avoid scratching them since it spreads the rash.
