Acne: Treatments, Causes and Types

Online acne treatment has become an increasingly popular solution for people who face this skin condition on a recurring basis. Through medical treatment, it is possible to obtain diagnosis, prescriptions and specialised medical follow-up. In this article we explain the causes of acne, the main types of acne and how to get effective treatment with medical support.

What is Acne?

Acne is a inflammatory skin disease which affects the hair follicles and sebaceous glands. It is mainly caused by excess sebum production, clogged pores, bacterial proliferation and hormonal imbalances. The causes of acne vary from person to person, but the most common factors include:

  • Hormonal changes (puberty, menstruation, pregnancy)

  • Use of cosmetics or medicines that clog pores

  • Genetic factors and family predisposition

  • Diet high in sugar and dairy products

  • Stress and emotional changes

Comedonal acne

  • Presence of blackheads and whiteheads (comedones)

  • Often affects the T-zone (forehead, nose and chin)

Inflammatory acne

  • Red pustules, pimples and nodules

  • More painful and visible, it can leave marks

Cystic acne

  • Deep lesions with cyst formation

  • Requires specialised medical care

Most commonly used acne medicines

The acne medicines vary according to the degree and type of the condition. The most commonly prescribed include:

  • Topical retinoids (retinoic acid, adapalene)

  • Oral or topical antibiotics (clindamycin, doxycycline)

  • Hormonal contraceptivesfor women

All treatments must be prescribed by a certified health professional, based on an individualised assessment.

Complementary Care

In addition to medical treatment, it's important:

  • Wash your face with gentle, non-comedogenic products

  • Avoid squeezing pimples to prevent scarring

  • Maintaining a balanced diet and hydration

  • Use sun protection even on acne-prone skin

  • Reduce stress and improve sleeping habits

In short, acne is a condition that can have a significant impact on self-esteem and quality of life, but there are effective and affordable solutions for controlling it. Medical supervision, whether in person or online, remains essential to identify the most appropriate treatment for each case. By understanding the causes and types of acne, you can make informed decisions and look after your skin's health responsibly and safely.
