Blister on lip

What makes people think that a small blister on their lip is not a cold sore? Lip blisters are general conditions that show up on the skin following an injury, trauma, or environmental causes. The lips are susceptible, affecting them by mild inflammation and the development of blisters.

Compared to cold sores, blisters are not contagious. They also heal faster than cold sores. Lip blisters happen naturally due to lip bite, hot beverage, or environmental circumstances. It also explains why excessive exposure to the sun triggers blisters. A sunburn causes the lips to swell and blister on and around the lips.

There can be different forms of blisters on the lip. It can range from water blisters, red bumps and even pimples. Read on to learn more.


Water blister on lip

A water blister on the lip is identified by its appearance. It is a small sac on the skin filled with fluid. It can be treated quite simply compared to fever blisters. However, careful treatment is necessary to avoid scarring on the lips.

There are a variety of reasons water blisters occur. These include friction, heat burn, contact dermatitis, eczema, an allergic reaction, poison oak, and frostbite. Some water blisters also heal on their own; however, keep them clean and protect them from friction.

If the water blister is large and painful, draining it is an option. Use a sharp needle to pop the sac. Apply an absorbent pad to the affected area after poking. Drain the fluid until nothing is left. Apply ointment to the blister area and cover it with a non-stick gauze bandage.
