Acne, or acne vulgaris, is the medical term for pimples. It is characterized by blackheads, red bumps, pustules and sometimes inflammation. Although it mainly occurs on the face, acne can also occur on the back and
chest, as in the more severe form of acne conglobata, which primarily affects young men. Although acne is most common during puberty, it can persist at any age and in both sexes.

Although the exact cause of rosacea is still unclear, we know that external factors such as sunlight, temperature changes, certain foods, cosmetics and emotions can aggravate the symptoms.
can worsen. These factors can trigger rosacea flare-ups, also known as flushes.

Pimples are caused by an inflammation of the sebaceous glands and hair follicles, in which several processes play a role: an increase in sebum production, accumulation of dead skin cells and the presence of bacteria
C. acnes, which causes inflammation.

There is no single cause of acne; often it is a combination of factors. The most important are:

Genetic predisposition:

If family members have had severe acne, you are more likely to get it too.

Hormonal changes:

Especially during puberty, pregnancy or menstruation, hormones such as testosterone and insulin can increase sebum production.

External factors:

Poor skin care, humidity, chafing clothing or even face masks can make acne worse.

Nutrition and lifestyle:

Dairy, sugars, smoking and stress can promote pimples.

Medicines:

Some medications, such as corticosteroids and birth control pills, can cause acne.

Microbiome:

The bacteria on your skin and in your intestines also play a role in acne.

Not all pimples are the same. There are different types of acne, such as:

Hormonal acne:

Caused by hormones such as testosterone, which increase sebum production and clog pores. This type is often aggravated by stress and a diet high in sugar or dairy.

Pimples due to inflammation:

These can be caused by allergies or intestinal problems and are often more superficial.

Pimples caused by yeast and mites:

Yeast pimples are small and skin-colored and can be itchy, while mites, such as demodex, play a role in rosacea and inflammation.

Irritating pimples:

Often caused by overly aggressive skin care, these pimples usually disappear when you leave your skin alone.

Rosacea or clown eczema:

Sometimes it looks like acne, but it is actually rosacea, with redness and sensitive skin being the main features.
