Acne causes spots and oily skin. Sometimes it can cause skin that's hot or sore to touch.
Types of acne spots
There are 6 main types of spot caused by acne:
Blackheads are small black or yellowish bumps that you can get on your skin. They're not filled with dirt. Their colour comes from the inside of a tiny hole in the skin which has become blocked.
Whiteheads look like blackheads, but may be firmer and do not empty when squeezed.
Papules are small red bumps that may feel tender or sore.
Pustules are like papules but have a white tip in the middle. A build-up of pus causes them.
Nodules are large hard lumps. They build up under your skin and can be painful.
Cysts are large pus-filled lumps. They look like boils. If you have these, you are at more risk of getting permanent scarring.
Different levels of acne symptoms
You can have different types of spots depending on how bad your acne is.
You have mild acne when you have whiteheads and blackheads, with a few papules and pustules
When you have more whiteheads and blackheads, with many papules and pustules you have moderate acne.
Severe acne is when you have sore papules, pustules, nodules or cysts. You might also have some acne scarring. This happens when spots burst and damage your skin.
