It’s not just teenagers who get acne. While blemishes are most common during puberty, even babies can be affected and some people develop acne prone skin in adulthood.

Acne is sometimes labelled according to the age at which it occurs: baby acne, teenage acne, adult acne etc., but it is also described according to the severity of its symptoms (e.g. Acne Conglobata) and, at other times, the various forms of acne are grouped according to the external causes that may have triggered blemishes (e.g. Cosmetic and Mallorcan Acne).

This article looks at all three different ways of grouping acne and explains the names, likely triggers and symptoms of each different type.

We use terms such as comedones, papules and pustules to describe the different forms of acne. If you’re not familiar with these, you can find an explanation of the terms used to describe blemishes in Acne-prone skin in general.

If you’d like to find out more about how blemishes and acne develop, take a look at the development of acne and the causes and triggers of acne. For how to care for skin, read the ideal skincare products and routine for acne-prone skin and acne medication and common treatments.

This article may help you identify the type of acne that you have but, if you are still in doubt after reading it, and if your skin is causing you problems, then you should consult your doctor who will be able to give you the information and advice you need.

Acne at different life stages

Our hormones behave differently at different stages of our life. This means that acne, for which the primary internal cause is hormonal, varies depending on our age. You can read more about the relationship between acne and hormones here. Acne is most likely to occur when hormones are fluctuating and is broadly categorised into four different age-related types:

The different forms of acne when grouped by external causes

Acne Aestivalis

Girl picking on face spots
Constant picking of spots can lead to Acne Excoriée

Also known as

Mallorca acne


When does it occur?

It is most common in women aged 25-40, many of whom have had a history of acne in puberty. It appears after exposure to UV radiation, and is likely to be caused by the free radicals (created by exposure to the sun) reacting with the emulsifiers in cosmetic and sun protection products.


Where does it occur?

The most frequently affected areas include the underside of the arms, the chest and, less often, the face


Symptoms

They may include a bumpy rash, skin redness, blisters or pustules, and are nearly always accompanied by intense irritation. In more severe cases larger, haemorrhagic lesions can occur. 


Can it scar?

Yes, but pigmentation issues are a more likely consequence of Acne Aestivalis.

Acne Cosmetica

Also known as

Cosmetic acne, make-up acne


When does it occur?

It occurs when skin reacts to the comedogenic substances in some cosmetics. These substances block the sebaceous glands and trigger acne. Symptoms normally subside when you stop using the product.

Anywhere on the body, but it is most common on the face, neck, hairline and scalp.


Symptoms

Mild but persistent. Lots of small bumps on the skin that make it feel rough but usually little or no visible inflammation.

Generally on the face (forehead, nose and cheeks) as it’s easily accessible. 


Symptoms

Can exacerbate the symptoms of mild acne and spread bacteria leading to greater inflammation.
