Complément alimentaire et acné : peut-on vraiment soigner sa peau de l'intérieur ?

Dietary supplements and acne: Can you really treat your skin from the inside?

The gut-skin axis: a scientifically proven connection

The skin is not an isolated organ. It is deeply connected to the entire body, notably to the digestive system. The gut-skin axis is today an active research field in dermatology: scientists have shown that the state of the gut microbiome directly influences skin health. An imbalance in gut flora (dysbiosis) can manifest as inflammation, acne, eczema or psoriasis.

Which micronutrients really act on acne?

Not all supplements are equal. Here are the actives whose role is documented by clinical studies:

Zinc

Zinc is the most studied trace element linked to acne. Zinc contributes to the maintenance of normal skin (EFSA-authorised health claim). Its mechanisms of action:

  • Regulates sebum production by sebaceous glands
  • Participates in skin microbiome balance
  • Has anti-inflammatory properties
  • Promotes healing of skin lesions
  • Activates cell division and renews surface layers of the epidermis

Studies have shown that people with acne often have lower-than-normal zinc levels. Adapted supplementation can support better skin balance.

Lactoferrin

Lactoferrin is a glycoprotein naturally present in breast milk and biological secretions. Its biological role is recognised in:

  • The chelation of iron needed by certain bacteria to multiply
  • The support of natural skin defences
  • The modulation of inflammatory response
  • The support of skin microbiome balance

Published work has evaluated its interest in acne management after 8 to 12 weeks of intake. Lactoferrin has no EFSA-authorised health claim specific to the skin: its role is factually described.

Vitamin B6

Acne breakouts are often linked to hormonal fluctuations: menstrual cycle, stress, puberty. Vitamin B6 contributes to the regulation of hormonal activity and participates in normal protein metabolism. It helps the body better manage variations that can amplify sebum production.

Vitamin C

Vitamin C contributes to normal collagen formation, giving skin its firmness and participating in healing processes. As an antioxidant, it contributes to protecting cells against oxidative stress.

Copper

Copper contributes to protecting cells against oxidative stress and participates in normal immune system function.

How and when to take an anti-acne supplement?

For optimal use:

  • Regularity is essential: first effects are visible after 4 to 8 weeks. It is recommended to maintain intake for at least 3 months to evaluate support.
  • Preferably with a meal: this improves digestive tolerance. If you feel discomfort, take capsules with breakfast.
  • As a complement to a topical routine: dietary supplement is not an isolated treatment. It acts synergistically with topical skincare for a holistic skin approach.

Supporting acne from the inside is a scientifically credible approach. Zinc, lactoferrin, vitamins B6 and C, copper: these actives all have a documented role in skin balance. Zactigis SkinCTRL combines these actives in studied proportions for a holistic and gentle approach. Made in Switzerland.
