There are a few reasons a pimple might not be going away. It's normal for some types of acne—especially deep, large pimples—to take some time to clear up. You might also have persistent pimples if you're not taking care of your skin, taking certain medications, or have certain health conditions.
When to see a doctor. Pimples are a common and usually harmless skin condition. However, if they do not go away or improve with at-home treatment, it may be time to see a dermatologist. The dermatologist will identify the type of pimple and determine the best course of treatment.
Unlike regular pimples that often heal within a few days, acne nodules may last for weeks or months. They tend not to develop a white head and may remain as hard knots under the skin. Nodular acne can be painful, and its appearance may affect a person's self-esteem.
“If you pop the pimple, it becomes a micro-wound,” explains Kazin. At this point, it's best to apply a little antibiotic ointment like Neosporin ($6, drugstore.com) at night to help speed up healing. Allowing it to “breathe” during the day without anything on it, if possible, will also help it mend faster.
Neosporin does not kill the most common acne-causing bacteria, so it won't typically be effective at fighting pimples or cystic acne. Because it has many moisturizing, skin-healing oils in its ingredients, Neosporin may temporarily tame irritation and also heal areas of damaged, broken skin.
A melanoma pimple will typically present itself as a firm red, brown or skin-colored bump that many doctors may misdiagnose as a pimple or harmless blemish. The main difference to note is that these bumps will not feel soft like a pimple, but rather will be firm or hard to the touch.
Hard pimples are caused when dead skin cells, oil, and bacteria get under the skin's surface. Certain types of hard pimples should be treated by a doctor to prevent them from getting worse and leaving scars.
Underground pimples that swell up and never come to a head (known as cystic acne) are notorious for showing up in the same exact spot, says Dr. Zeichner. They develop when your pore, which is shaped like a long tube, branches out and causes oil to take a detour from its path to the surface of your skin.
Pimples usually last between three and seven days. Most pimples go away on their own, but it may take some time. Deep pimples (pimples under your skin with no head that may feel hard to the touch) may take a few weeks to go away, if not longer.
On the surface, cystic acne can look like large, red boils. Cysts, like nodules, reside deep underneath the skin's surface. But because they're filled with pus, cysts are softer than nodules. The pimples that define cystic acne burst open, often leading to infection.
Because popping isn't the way to go, patience is the key. Your pimple will disappear on its own, and by leaving it alone you're less likely to be left with any reminders that it was there. To dry a pimple up faster, apply 5% benzoyl peroxide gel or cream once or twice a day.
Often, the surface of the skin will have swollen, red bumps that are incredibly painful to touch, as the cysts underneath are inflamed. If ignored, cysts can take anywhere from 1-4 weeks to go away by themselves.
It can take three months or more to clear up acne cysts. Treatment often involves taking oral antibiotics and applying prescription-strength topical gels or creams to the skin. Cystic acne treatments include: Antibiotic creams, gels solutions and lotions to kill bacteria and decrease inflammation.
Nodular acne requires treatment from a dermatologist (a healthcare provider who specializes in caring for your skin). Without treatment, this type of pimple can lead to permanent and severe scarring. You can reduce your risk of scarring by seeking treatment as early as possible.
"It is due to androgen activation of sebaceous glands," says Dr. Robinson. "It occurs in the same area as this is the area on our face in which the androgens activate our sebaceous glands." Meaning your lower cheeks, chin, jawline, and neck are right in the line of fire.
Examples include white bread, corn flakes, puffed rice, potato chips, white potatoes or fries, doughnuts or other pastries, sugary drinks such as milkshakes, and white rice. Findings from small studies suggest that following a low-glycemic diet may reduce the amount of acne you have.
If pain and swelling are severe or you have a pimple that doesn't go away, see your healthcare provider. You may need to see a dermatologist (a provider who specializes in caring for the skin).
A sebaceous cyst will grow into a moveable, sometimes significantly large (up to two inches in diameter) mass beneath the skin. Sebaceous cysts can grow and develop in weeks, months or even years. Acne, on the other hand, is characterized by smaller, more conical-shaped growths, often with a visible whitehead.
They're great for wounds and for blisters. For acne lesions, the bandages can be applied directly on pimples and help decrease inflammation, redness and irritation, and they can absorb drainage from active acne blemishes.
If you're bleeding, she says to “gently blot the area with a clean tissue or cotton pad and clean the area with alcohol.” Once the blood has stopped, she advises applying a spot treatment containing benzoyl peroxide or salicylic acid as mentioned above.
Products that contain salicylic acid, benzoyl peroxide, or a retinoid are the key, our experts tell us. In particular, Dr. Elbuluk recommends trying over-the-counter salicylic acid and benzoyl peroxide products.
