The health of the skin depends 80% on what we eat and 20% on external factors . Diet therefore plays a key role in maintaining the quality and beauty of the skin. A recent discovery that is shaking up the cosmetics market with the arrival of a new category of products: food supplements. Who are they, how do they act and which ones to choose to have beautiful skin? Discover the underside of this new beauty gesture.



What is a food supplement?


A food supplement is a foodstuff concentrated in active substances which constitute an additional nutritional contribution for the organism (National Agency for Food, Environmental and Occupational Health Safety - ANSES).

Depending on their composition, their dosage or their mode of intake, food supplements can fill potential deficiencies or strengthen certain functions of the body. They are found in different forms: liquid extracts, capsules, tablets, powders or even gummies, these little colorful jelly candies that flourish on the consumer and selective beauty shelves.

If their use is rather common in the sectors of health and sports performance, they are also proving to be real allies for taking care of the skin. For what ? How do they actually act?


In an ideal world, food should be enough to provide the body with the nutrients it needs. The reality is not so simple and it is not rare that the nutritional contributions do not cover the physiological needs specific to each one. Indeed, at present, foods, even organic ones, are increasingly poor in nutrients and, conversely, the body needs them more and more to fight against the oxidative stress generated by the rhythm of life. unbridled and the various pollutions to which it is exposed.

Deficiencies can jeopardize the proper functioning of our systems, and the skin, like any organ, is no exception to this rule. By providing the necessary micronutrients directly to our cells via the bloodstream, food supplements can help correct certain imbalances that cause skin problems.


You are probably wondering which ones to choose to have beautiful skin? To each problem its solution.



Effective dietary supplements for beautiful skin


Lack of hydration, wrinkles and loss of firmness, adult acne… Whatever your concerns, there is sure to be a food supplement to help you deal with them, in addition to a suitable skincare routine.

Here are some key active ingredients to look for in the composition of food supplements to have beautiful skin.


Maintain optimal hydration

Tightness and redness are the main signs of dehydrated skin. There are several active ingredients that act to maintain good skin hydration, for example:

  • hyaluronic acid: this is one of the flagship active ingredients in cosmetics, recognized in particular for its exceptional moisturizing and plumping power.

  • omega 3, 6 and 9: these polyunsaturated fatty acids are all the more interesting in complementation as the body does not synthesize them. It is therefore necessary to take care to integrate them into the diet in particular. They stimulate the natural production of hyaluronic acid and fight against skin dehydration. The Omega 3 DHA contained in the Days of Confidence Radiance Complex are particularly useful in restoring suppleness and elasticity to the skin.


Do not forget that water intake remains the best way to have properly hydrated skin: drink at least 1.5 liters per day, favoring quality water (spring water, filtered water) and low mineral content.


Fight against skin aging

After 25 years, the body's ability to synthesize the structural elements that give the skin its firmness and tone decreases. Some food supplements are concentrated in active ingredients that help fight against the signs of skin aging.

  • collagen: it maintains the hydration and structure of the skin from the inside for a filling and smoothing effect.

  • vitamins A, C, E: they fight against oxidative stress partly responsible for skin aging. Combined with 11 other active ingredients in the formula of Vitality complex from Days of Confidence, they help maintain the elasticity and firmness of the skin.

  • hyaluronic acid: him again! Thanks to its plumping power, it smoothes fine lines and restores skin tone.


    Treat acne and blemishes

    About 25% of women suffer from adult acne ( If you are concerned, know that there are natural active ingredients that help to reduce the effects.

    • zinc: recognized for its anti-inflammatory and healing properties, it harmonizes the activity of the sebaceous glands and promotes healing.

    • evening primrose oil: effective against hormonal acne, it regulates sebum secretion and purifies the skin. It is also recognized for its anti-inflammatory, moisturizing and anti-aging properties, which makes it a great ally for the beauty of the skin.


    When it is not of hormonal origin, acne in adults can be linked to an excessively high level of toxaemia, that is to say an accumulation of acid and mucosal waste in the body. At Days of Confidence, the Detox Complex , enriched with chlorella, gently detoxifies to regain a fresh and radiant complexion.
