Acne: the most effective dietary supplements

Acne is a chronic inflammatory condition affecting the pilosebaceous follicles and manifesting as outbreaks of pimples. This condition affects 70 to 80% of adolescents, with lesions that can sometimes leave scars. It generally appears at puberty and disappears in most cases in adulthood.

Symptoms and Types of Acne

Acne lesions can be comedonal (retentional), such as comedones (blackheads and whiteheads), or inflammatory, such as papules, pustules, or nodules. Juvenile acne is the most common form, occurring mainly on the face and back, but some rare forms, such as choroidal acne, affect specific areas like the forehead.

Causes of Acne

Seborrhea, characterized by excessive sebum production, is a key factor in the development of acne. This phenomenon often begins at puberty, linked to an increase in androgens (such as testosterone), which stimulate the sebaceous glands. In addition, receptors located on the sebaceous gland, such as those for histamine, cholesterol (PPAR), or insulin, can also influence sebum production. Note that an imbalance of the gut microbiota can exacerbate acne. Although some researchers have explored the link between diet and acne, particularly regarding simple sugars and dairy products, no definitive evidence has yet been established.

Acne Treatment

Acne treatment aims to reduce sebum production, limit bacterial infections, and soothe inflammation. Options include: • Topical treatments : Retinoids, antibiotics, and azelaic acid are effective for mild to moderate forms. • Oral treatments : In more severe cases, oral antibiotics or isotretinoin may be prescribed. In women, oral contraceptives regulate the hormones involved in acne. • Zinc : An effective alternative to antibiotics, without the risk of photosensitization. Zinc treatment starts with a dose of 30 mg/day for three months, then 15 mg/day for the following three months. Vitamin D (1,000-5,000 IU/day) helps reduce inflammation, while burdock extracts and green tea provide soothing and anti-inflammatory properties.

Prevention and Care

Good skin hygiene is crucial for preventing and managing acne. It is recommended to cleanse the skin daily with gentle, non-irritating products, to avoid popping pimples to prevent scarring, and to apply an appropriate moisturizer. Although the link with diet is not definitively proven, adopting a diet low in simple sugars and dairy products may contribute to better skin health.
