6 Types of Acne and What Might Cause Them

2 years ago

There are 2 categories that acne blemishes fall under. This depends on if they cause inflammation or not. That being said, there’s noninflammatory acne and inflammatory acne. Inflammatory acne is more severe compared to noninflammatory, and most of the time, you need to consult your doctor for treatment.

We at Bright Side want to explain what causes the most common types of acne before you move forward with treatment.


These are noninflammatory flesh or whitish-colored bumps or spots that typically have a white center surrounded by a red halo. In some cases, hair might come out from the center or it will seem trapped inside.

Causes: Whiteheads form thanks to dirt, oil sebum, and dead skin cells clogging the pores. These are closed within the pore.


Just the opposite of whiteheads, blackheads (noninflammatory) are dark or black-colored small spots that appear as raised bumps. Usually, the skin surrounding the blackhead is normal and the center is darker.

Causes: Just because they’re darker in color doesn’t mean these blemishes have more dirt in the pore. It’s just a sign that the pores are widened and are caused by clogged hair follicles.


Papules are inflammatory acne that is located under the skin’s surface. The skin that surrounds these blemishes is usually red and swollen. They are raised, pink, solid, and tender. But compared to the 2 types of noninflammatory acne, they don’t have a visible center and aren’t widened.


  • Skin infection (Molluscum contagiosum)
  • The development of small blood vessels (cherry angioma)
  • Warts
  • Eczema
  • Allergic reaction

Pustules, otherwise known as pimples

Pimples are tender, larger bumps that have a circular center. The center is filled with yellowish/whitish pus over a red skin base. In fact, they look a lot like larger whiteheads but inflamed.


  • Allergic reaction most commonly to food, or environmental allergens
  • Insect bites (poisonous)
  • When the skin gets clogged with dead skin cells and oil


The inflamed, painful, and hard lumps that are located deep in the skin are known as nodules. This type can become severe and may cause skin complications like scarring and dark spots.

Causes: These are considered inflammatory acne and are formed when clogged pores damage the cells and tissue deep beneath the surface of the skin.


When pustules become infected they start to become painful. This is when pustules become a cyst. Cystic acne consists of white or red, painful, large, and yet soft lumps that are located deep in the skin — even deeper then nodules. They are also filled with pus. In fact, these are considered to cause severe skin complications like scarring.

Cause: infected pustules

Do you suffer from acne? What type? What treatment has helped you?


I’ve struggled with adult acne and oily skin for some time but I’m glad I started using DermalMD Acne Serum. I use the cleanser before applying the serum treatment and I haven’t had any break outs in about 3 weeks when I started using it. I saw results in about 3-4 days plus a little bit goes far so you get your money’s worth. I would definitely try these two products if you’re like me!
Interesting! I guess these help us know how to take care of these little problems
I have just realized that I have nodules ?

I wish I knew how to get rid of those!
