Acne is not just a cosmetic issue but a complex inflammatory skin condition that affects millions of people worldwide. According to the American Academy of Dermatology (AAD), acne affects up to 50 million Americans annually. In Europe, the prevalence of acne is approximately 5.36% of the population, making it one of the most common skin conditions.
Recent scientific research has significantly expanded our understanding of acne causes and effective treatment options. Multiple factors contribute to acne, including:
- Hormonal fluctuations
- Disruptions in the skin microbiome
- Genetic predisposition
- Environmental factors
- Diet and lifestyle
This guide explores not only the most effective acne treatments but also cutting-edge scientific research to help you choose the best way to combat breakouts.
What Causes Acne? Understanding the Key Factors
1. Hormonal Changes
Hormones play a crucial role in acne development. High levels of androgens (male sex hormones) stimulate sebaceous glands, leading to excessive oil production and clogged pores. This explains why teenagers, pregnant women, and individuals with polycystic ovary syndrome (PCOS) are more prone to acne.
2. Skin Microbiome Imbalance
Previously, acne was thought to be solely caused by Cutibacterium acnes bacteria. However, modern research has shown that the skin microbiome plays a much more complex role. An imbalance between beneficial and harmful bacteria increases inflammation and worsens skin conditions.

Pollution, high humidity, and prolonged sun exposure can exacerbate acne. Additionally, stress triggers the release of cortisol, which increases oil production and contributes to inflammation.
4. Diet and Acne: What Research Says
Scientific studies suggest that certain foods may worsen acne:
- High-glycemic foods (sweets, pastries, soda) contribute to inflammation.
- Dairy products, particularly cow’s milk, can elevate insulin and androgen levels, worsening breakouts.
- A deficiency in omega-3 fatty acids and zinc has been linked to increased acne susceptibility.
