Skin lesions are commonly described as unnatural looking parts of the skin. Some are (potentially) dangerous, while others are just problematic from an aesthetic point of view. Luckily most of the types of skin lesions can be treated pretty easily. Here you can read what different lesions are exactly, and how they look:


Although not dangerous, rashes can be pretty annoying. It’s basically an allergic infection and mostly appears in the form of small red dots – but it can vary in size. Rashes are the type of skin lesion that covers parts of the body, not the whole skin.


You could probably guess by the name: pustules are small spots filled with pus. They can get itchy, and are hard to get rid of. Pustules are (mostly) harmless skin lesions, but they can result in scars if treated badly or if they appear often for a longer period of time.


As acne is the most common type of pustules, we want to highlight this separately. Acne comes in the form of small red spots, often filled with pus. These can itch, but will mostly be an aesthetic issue for anyone dealing with acne. It’s not dangerous, but these types of skin lesions will require a specialist to look at for custom treatment.

5 Essential Steps to Healthy Skin


The types of lesions people suffering from psoriasis come across may differ, but plaques are the most common. Plaques come in the form of patches of several smaller skin lesions and can appear anywhere on the skin. They can be treated pretty easily but can reappear just as quickly.


We all have had blisters at certain parts of our lives. These are harmful skin lesions: they come from sunburns, steam- or fire burns or insect bites. Blisters are small lesions filled with fluid and will disappear on their own. Actively treating them can speed up that process.


Wheals are skin lesions that are caused by an allergic reaction and the most common type of wheals are hives. They come as groups or patches of spots. Hives can be itchy or even burn/sting. They can last for hours, with up to one day in some cases, before disappearing by themselves. Hives are not dangerous but can be pretty annoying of course.

Skin cancer

The most dangerous types of skin lesions are skin cancer moles. Normal moles are of course a natural thing and do no harm. But they always pose a certain risk: if a mole changes in color, size or form it can be dangerous due to skin cancer risk. Make sure to have a mole checked out if you don’t trust it.

These are the most common types of skin lesions. The majority is harmless, but with any changing skin spots: do a self-check or see a doctor if you feel uncomfortable.
