Essential nutrients for healthy skin


To maintain the skin's radiance, it is essential to provide it with the nutrients it needs. Among the most important are:


  •  Vitamin C: a powerful antioxidant, it protects the skin from free radicals responsible for premature aging. It also stimulates the production of collagen, a protein that gives the skin its firmness and elasticity.

  •  Biotin: Biotin, also known as vitamin B7, is important for healthy hair, skin, and nails. It helps maintain skin hydration and prevent inflammation.

  •  Niacin: Niacin, or vitamin B3, is an essential nutrient that plays an important role in repairing skin cells and reducing redness. It can also help improve skin elasticity and reduce the signs of aging.

  •  Vitamin E: Vitamin E is another powerful antioxidant that protects the skin from damage caused by free radicals. It also helps maintain skin hydration and prevent wrinkles and fine lines. Discover ourtop 5 best sources of vitamin E.

  •  Omega fatty acids: Omega-3 fatty acids are essential fatty acids that help maintain skin hydration and reduce inflammation. They can also help prevent acne and eczema.


A diet rich in fruits, vegetables, whole grains, and lean proteins is therefore essential to provide your skin with the nutrients it needs to stay healthy and radiant.

Signs of nutrient deficiency


Lack of nutrients? Our skin shows it. Here are some skin signs that may indicate nutrient deficiencies:


  • A dull, pale complexion can be a sign of iron, vitamin B12, or folic acid deficiency. Acne can be caused by hormonal imbalance, but also by zinc or essential fatty acid deficiency.


  • Dry skin can be a sign of a deficiency in essential fatty acids, vitamin E, or vitamin D. A vitamin A deficiency can also weaken the skin and make it more sensitive to external aggressions.


  • The lips and tongue can also reveal signs of nutritional status. Dry, chapped lips or mouth ulcers may indicate a vitamin B or vitamin C deficiency.


  • Brittle, ridged nails can be a sign of iron, zinc, or vitamin B deficiency.

Solutions for beautiful skin


To restore clear, radiant, and hydrated skin, it is essential to implement effective solutions.


Food sources


Choose a diet rich in fruits and vegetables, lean protein sources, fatty fish, and vegetable oils. Here are some examples of foods rich in nutrients for the skin:


  • Vitamin A: carrots, spinach, sweet potatoes, liver

  • Vitamin C: citrus fruits, peppers, broccoli, kiwi

  • Vitamin E: almonds, sunflower seeds, vegetable oils

  • Zinc: oysters, red meat, pumpkin seeds

  • Essential fatty acids: fatty fish, nuts, chia seeds


Adopt a good skincare routine 


In addition to a healthy diet, it is important to adopt a good skincare routine. Here are a few tips:


  • Clean your skin morning and night with a gentle product that's right for your skin type.

  • Moisturize your skin daily with a moisturizing cream or serum.

  • Use sunscreen with SPF 30 or higher every day, even in winter.

  • Exfoliate your skin once or twice a week to remove dead skin cells.


Our Organic SOS Blemish Roll-Onis a targeted treatment that helps combat blemishes and pimples. Its formula, enriched with organic tea tree and lavender essential oils, purifies the skin and cleanses the affected areas.



By adopting a healthy diet, a good skincare routine, and supplementing these two habits with dietary supplements, you give your skin everything it needs to be beautiful and radiant.
