Why use a dietary supplement for the skin?
The skin is the largest organ in the human body and directly reflects our overall health. While topical treatments (creams, serums) act on the surface, dietary supplements nourish the skin from within, where it regenerates.
- Preventing skin aging: With age, the natural production of collagen and hyaluronic acid begins to decline as early as age 25. Supplementation helps compensate for this loss and preserves firmness and elasticity. Discover our guide on anti-aging dietary supplements to learn more about this topic.
Addressing nutritional deficiencies: An unbalanced diet, stress, or certain lifestyle factors (smoking, sun exposure) deplete reserves of essential nutrients. Supplements provide these elements in a concentrated and bioavailable form.- Support against external aggressors: Pollution, UV rays, and oxidative stress attack the skin daily. The antioxidants present in supplements (vitamin C, vitamin E, zinc, turmeric) neutralize free radicals responsible for premature aging.
- Enhanced deep hydration: Hyaluronic acid and certain vitamins promote water retention in skin tissues, for plumped and hydrated skin from within.
- Targeted action on specific problems: Acne, redness, dryness, loss of radiance... Supplements allow you to act in a targeted way according to your particular needs.
Complementarity with external treatments: Used in synergy with a suitable skincare routine, food supplements maximize results and offer a comprehensive and sustainable beauty approach.
The benefits of dietary supplements for the skin
Enhanced hydration
Hyaluronic acid supplements increase the skin's ability to retain water, thus reducing dehydration and feelings of discomfort. The skin appears plumper, smoother, and more comfortable.
Brightness and luminosity
Antioxidants such as vitamin C, zinc, and plant extracts stimulate cell renewal and even out skin tone. The result: luminous skin and a radiant complexion.
Anti-aging action
It improves firmness , reduces wrinkles and fine lines, and redensifies skin tissue. Combined with vitamin E and selenium, it protects against oxidative stress responsible for premature aging.
Protection against attacks
Vitamins C and E, zinc, selenium, and turmeric strengthen the skin's natural defenses against UV rays, pollution, and free radicals. They preserve cellular integrity and limit skin damage.
Reducing imperfections
Zinc, B vitamins, and MSM regulate sebum production, soothe inflammation, and promote healing. Ideal for acne-prone skin.
Calm and repair
Essential fatty acids (omega-3), vitamins and certain antioxidants reduce redness, soothe sensitive skin and strengthen the skin barrier for better resistance to irritation.
What nutrients does my skin need?
Marine collagen
Collagen, an essential structural protein, makes up 75% of the skin's composition. It maintains firmness, elasticity, and density. Marine collagen, which is highly bioavailable, compensates for the natural age-related decline in production and redensifies tissues for firmer, more supple skin.
Hyaluronic acid
Hyaluronic acid can hydrate the skin from within, plump up facial features and smooth dehydration lines. It maintains skin elasticity.
Vitamin C
A powerful antioxidant, vitamin C stimulates collagen synthesis, protects against oxidative stress, evens skin tone, and provides radiance and luminosity. In the form of organic acerola, it is even more effective and better absorbed by the body.
Vitamin E
This fat-soluble vitamin protects cell membranes from oxidative stress, preserves skin hydration, and improves skin elasticity. It works synergistically with vitamin C for enhanced antioxidant protection.
Zinc
Zinc, an essential mineral for skin health, regulates sebum production, promotes healing, reduces inflammation, and supports cell renewal. It's indispensable for blemish-prone skin and for maintaining healthy skin.
Biotin (Vitamin B8)
Biotin contributes to the maintenance of normal, healthy skin. It participates in the metabolism of essential fatty acids and plays a role in the overall health of the skin, hair, and nails.
Turmeric
A powerful anti-inflammatory and natural antioxidant, turmeric protects the skin against oxidative stress and external aggressors. Its curcumin helps soothe skin inflammation, evens out skin tone, and promotes radiance. It is particularly beneficial for skin prone to redness and irritation.
Spirulina
This exceptional microalga is rich in protein, B vitamins, iron, beta-carotene, and antioxidants. Spirulina helps the body protect itself against the effects of oxidative stress, and it may also contribute to a more radiant complexion.
Glycine
An amino acid involved in collagen synthesis, it is said to improve skin quality. It has antioxidant and anti-inflammatory benefits, which help maintain skin's beauty.

How to incorporate dietary supplements into your beauty routine?
The ideal time to take
Most skin supplements are taken in the morning with breakfast, along with a meal containing fats to optimize the absorption of fat-soluble vitamins (A and E). Hyaluronic acid and collagen are also better absorbed on an empty stomach or early in the day. Taking your supplement with a meal improves digestive tolerance and promotes nutrient absorption. Always take it with a large glass of water.
Duration and regularity
For an initial course of treatment, allow at least 3 months to see visible results in skin quality. Skin cell renewal takes approximately 28 days; therefore, several cycles are necessary. Consistency is key: take your supplement at the same time every day to avoid forgetting and maximize the benefits.
Synergies with your skincare routine
A double cleanse in the evening deeply removes impurities and prepares the skin to receive further treatments. Apply a moisturizer suited to your skin type to work synergistically with the supplements. Sun protection is essential every day, even in winter, to protect your skin and preserve the benefits of the anti-aging supplements.
