WHAT ARE THE TYPES OF ACNE? - Espace Skins Montreal


What is acne?
According to the Canadian Dermatology Association, acne is the leading cause of consultation.

Acne can appear at any age, i.e., in newborns, adolescence, and adulthood.

It is an inflammatory skin disease that occurs when pores are clogged with dead cells and excess sebum produced by the sebaceous glands.

Acne is more common in adolescents. But adults can have it.

Beyond the discomfort and physical pain caused to the skin, acne can also cause significant psychological suffering in people who suffer from it.

Inflammatory pimples tend to appear on the face most often. But people with acne can also have pimples on the body, particularly on the neck, chest, back, shoulders, upper arms and buttocks.

Acne is a complex inflammatory disease whose causes are multifactorial. Stress, hormonal disorders, and using inappropriate products or diet are all factors involved.

For effective treatment, knowing the different types of acne is essential.

The different types of acne

Acne vulgaris (or common acne)
This is the most common form of acne. It is characterized by blackheads (open comedones), whiteheads, and small red and inflamed papules and pustules.

Cystic acne
This form of acne is one of the most serious because the microcysts and deep cysts (closed comedones) that form under the skin cause significant inflammation and pain.
Cystic acne can leave permanent scarring.

Acne rosacea
The presence of redness and dilated blood vessels on the face characterizes this form of acne, which can cause pimples similar to those of acne vulgaris.

Acne conglobata
This is a form of acne that is rare and particularly severe. Acne conglobata is characterized by the presence of interconnected nodules and cysts that can cause severe damage to the skin. In this case, medical care is necessary to implement specialized treatments.


Regardless of the type of acne, it is essential to consult a dermatologist to establish an accurate diagnosis and prescribe appropriate treatment.

Each type of acne requires a different, tailored approach, including prescriptions for topical medications, oral antibiotics, retinoids and other specific treatments.
