The gut-skin axis: a scientifically proven connection
The skin is not an isolated organ. It is deeply connected to the entire body, particularly the digestive system. The gut-skin axis is now an active research area in dermatology: scientists have shown that the state of the gut microbiome directly influences skin health. An imbalance in the gut flora (dysbiosis) can manifest as inflammation, acne, eczema, or psoriasis.
Which micronutrients truly affect acne?
Not all supplements are created equal. Here are the active ingredients whose efficacy against acne is documented by clinical studies:
Zinc — the best-documented anti-acne micronutrient
Zinc is the most studied trace element in the treatment of acne. Its mechanisms of action are numerous:
- It regulates sebum production by the sebaceous glands
- It inhibits the growth of Cutibacterium acnes
- It has anti-inflammatory properties
- It promotes the healing of skin lesions
- It activates cell division and renews the superficial layers of the epidermis
Studies have shown that people suffering from acne often have lower-than-normal zinc levels. Appropriate supplementation can significantly improve skin condition.
Lactoferrin — the anti-bacterial protein
Lactoferrin is a glycoprotein naturally present in breast milk and biological secretions. It acts on acne at several levels:
- It binds to the iron that bacteria need to multiply, thereby depriving Cutibacterium acnes of its main nutrient
- It has direct anti-inflammatory properties on the skin
- It regulates sebum production
- It strengthens the skin's immune defenses
In Switzerland, several studies have confirmed the effectiveness of lactoferrin in reducing acne lesions after 8 to 12 weeks of intake.
Vitamin B6 — hormonal balance
Acne breakouts are often linked to hormonal fluctuations: menstrual cycle, stress, puberty. Vitamin B6 plays an essential role in regulating hormonal metabolism. It participates in the synthesis of neurotransmitters and helps the body better manage hormonal variations that trigger excessive sebum production.
Vitamin C — antioxidant and regenerator
Vitamin C is essential for collagen synthesis, which gives skin its firmness and accelerates the healing of acne marks. As a powerful antioxidant, it neutralizes free radicals generated by inflammation and protects skin cells from oxidative stress.
Copper — cellular protection
Copper helps protect cells against oxidative stress and participates in immune defense mechanisms. It is often present in insufficient quantities in people suffering from inflammatory acne.
How and when to take an anti-acne supplement?
For optimal effectiveness, here are a few simple rules:
- Regularity is essential: The first results are visible after 4 to 8 weeks. Intake should be maintained for at least 3 months to assess effectiveness.
- Preferably on an empty stomach in the morning: Most active ingredients (lactoferrin, zinc) are better absorbed on an empty stomach. If you experience gastric discomfort, take them with breakfast.
- In addition to a topical routine: The dietary supplement is not a standalone treatment. It acts synergistically with topical care for a global action on acne.
Treating acne from within is not a marginal approach: it is a method validated by science. Zinc, lactoferrin, vitamins B6 and C, copper — these active ingredients act deeply on the mechanisms that trigger acne. Zactigis SkinCTRL has been formulated to combine these active ingredients in optimal proportions, offering a global and gentle approach to restoring balanced skin.
