As with pimples on other parts of the body, people should refrain from popping a pimple on their lip because this may cause it to become infected or leave a scar.
Pimples can develop over the entire face, including the border of the lip. When pimples appear on the border of the lip, they can easily be confused for a cold sore, especially in the early stages. Pimples never occur directly on the lip itself.
Lip pimples can be caused by lipstick, sweat, poor diet, and hormonal changes. If you have a lip pimple, don't squeeze it, apply salicylic acid, and use a warm compress. If you get acne frequently, talk to your dermatologist about getting prescription acne medication.
Acne around the mouth might develop from recurring pressure on the skin near the mouth, such as from daily cell phone use or a musical instrument. Cosmetics or other facial products, like toothpaste, lip balm, or shaving cream, might also be to blame. Hormones and genetics also play a role.
Pimples typically develop a white, yellow, or black head. Cold sores can last for 2–3 weeks. Large or swollen pimples can last for several weeks, while smaller pimples can often resolve within a few days.
Treatment for bumps on the lips depends upon the cause. Doctors can prescribe medications to treat infections. These include antifungal and antiviral medications along with antibiotics. Allergic reactions and dermatitis may be treated with antihistamine medications to reverse inflammatory reactions.
Both pimples and cold sores can develop heads too, but these tend to look different. Pimples can form blackheads or whiteheads, depending if the follicle remains open or if it closes, whereas a small amount of fluid often forms in cold sores.
Pimples don't occur on the actual lips, only on the skin with at the edge of the lips, the lip line. They occur at the lip line due to a high concentration of oil producing glands in that area. The lips themselves have no hair follicles, so no pimples can form there.
Making use of fruits like orange, tangerine and lemon can help you lighten the white spots on lips. Just blend the juice with some water and apply the mixture on your lips with cotton. The white patches will lighten and gradually disappear in a few days. This is a very simple home remedy to get rid of white spots.
