What nutrients are essential for healthy skin and hair?

Having radiant skin and healthy hair depends not only on the external treatments we apply, but also and above all on the nutrients we ingest on a daily basis, as well as the emotions that run through us.

Discover the most recognized external and internal nutrients for different skin and hair functions.


Moisturize and regenerate

Fatty acids play a crucial role in our overall health. While their impact on cardiovascular health is well known, fatty acids can also have beneficial effects on skin, hair and dry mucous membranes, as well as on hormonal balance and oxidative stress . Among fatty acids are omega 3 and 6, including gamma and alpha linoleic acid, and omega 7 and 9. Vitamin E protects these fatty acids from oxidation.


  • Omega 3

As well as making a significant contribution to cardiovascular health, lowering inflammation and enhancing skin and hair vitality, omega-3s play a major role in hormone synthesis. These hormones, in turn, the body’s messengers, regulate various biological processes, promoting cell regeneration, protecting against free radicals and preserving thelipid balance of the skin and scalp.

Incorporating these sources of fatty acids into our diet thus helps to support balanced hormone production, helping to maintain the beauty and vitality of skin and hair. Research in the“Journal of Cosmetic Dermatology” shows that these fatty acids help improve hair texture and prevent dryness of the scalp and mucous membranes (eyes and intimate area).

Both omega-3 and omega-6 are “essential” fatty acids, because humans are unable to produce them. They must therefore be supplied by our diet. EPA-DHA omega-3 fatty acids are mainly found in oily fish (salmon, mackerel) and seaweed oil , but are also less bioavailable in rapeseed oil and linseed. Ideally, you should mix vegetable and animal omega-3s, orseaweed oil with EPA-DHA for vegans.

  • Omega 6

Although very present in our diet, certain omega-6s are particularly important, such as linoleic acid. Maintaining the omega 6/omega 3 ratio plays an important role in inflammation mechanisms. Omega 6s help maintain the skin barrier, ensuring adequate hydration and helping to prevent dryness. They also help regulate sebum production, which can be beneficial for people with blemish-prone skin. Omega 6s, particularly linoleic acid, help reduce skin inflammation, promoting a balanced complexion. For hair, omega 6 helps nourish hair follicles, strengthening hair from root to tip.

Dietary sources rich in omega 6 include vegetable oils such as sunflower oil, corn oil and grapeseed oil.

  • Gamma and alpha linoleic acid

Alpha-linolenic (ALA) and gamma-linolenic (GLA) fatty acids are two types of essential fatty acid that are beneficial to skin and hair health.

  • ALA, an omega-3 fatty acid, is recognized for its anti-inflammatory properties, which can help reduce skin redness and inflammation. It also helps maintain skin hydration by strengthening the cutaneous barrier. Rich sources of ALA include flaxseeds, walnuts and flaxseed oil.
  • GLA, an omega-6 fatty acid, is renowned for its hormone-regulating and anti-inflammatory properties. It can help alleviate the symptoms of dry skin, eczema and acne by promoting the balance of skin lipids. Evening primrose oil and borage oil are rich sources of GLA.

For hair, these fatty acids play a vital role in scalp health. They help nourish hair follicles, promoting healthy hair growth. ALA and GLA also help maintain hair flexibility and elasticity, reducing dryness and brittleness.

  • Omega 7 and 9

The rarer omega 7, also known as palmitoleic acid, is mainly extracted from sea buckthorn oil. It is renowned for its moisturizing and skin-regenerating properties. Omega 7 boosts skin elasticity, promoting supple, smooth skin. It can also soothe dry, irritated skin, helping to restore an optimal moisture balance.

Omega 9, represented mainly by oleic acid, is found in oils such as olive oil. Omega 9 is renowned for its nourishing and regenerating properties. They help deeply moisturize the skin, maintaining moisture retention, which is ideal for dry or mature skin. These fatty acids also strengthen the cutaneous barrier, helping to protect the skin against external aggressions.

For hair, omega 7 and 9 deeply nourish the scalp. These fatty acids prevent scalpdryness, while adding shine and softness to hair.

  • Vitamin E

Vitamin E, a powerful antioxidant, helps protect the skin from damage caused by free radicals, helping to prevent premature skin aging. Vitamin E also promotes healing by helping to regenerate damaged tissue, helping to reduce the appearance of scars and blemishes.

As far as hair is concerned, vitamin E helps maintain a healthy scalp by improving blood circulation, thus promoting optimal hair growth. It also acts as a natural moisturizer, helping to prevent scalp and hair dryness. Research published in the“Journal of Drugs in Dermatology“, highlights vitamin E’s soothing properties, making it a versatile ingredient for bringing radiance and vitality to skin and hair.

Huile d'argousier

Extracted from the berries of the Hippophae rhamnoides shrub, sea buckthorn oil is famous for its richness in vitamins, notably vitamin C and vitamin E, as well as essential fatty acids such as omega 7. Vitamin C promotes collagen production, stimulating skin elasticity and reducing the signs of aging. Essential fatty acids, particularly omega 7, help to regenerate skin cells, promoting deep hydration and helping to soothe irritation. Sea Buckthorn oil’s anti-inflammatory properties are highlighted in theJournal of Clinical Medicine, suggesting its soothing potential for sensitive skin or skin conditions. This oil is exceptionally rich in carotenoids , giving it its distinctive dark orange color. Sea Buckthorn vegetable oil has a strong anti-free radical action and will stimulate the scalp and the production of keratin.
Seabuckthorn oil is thus a multi-faceted ingredient that can be used to nourish, protect and beautify the skin, making it a valuable ally in skin and hair care routines.


Borage, a plant with starry blue flowers, is a rich source of essential fatty acids, notably gamma-linolenic acid (GLA), an omega-6 fatty acid. Tests published in the Journal of Dermatological Treatment suggest that GLA plays a crucial role in regulating skin inflammation, helping to soothe skin irritations and maintain a healthy scalp. The fatty acids present in borage also help restore the skin’s lipid barrier, providing optimal hydration. What’s more, borage’s anti-inflammatory properties can help alleviate skin problems such as eczema and psoriasis. Whether consumed in the form of oil extracted from borage seeds or applied topically, this plant offers a natural approach to deeply nourishing the skin and maintaining healthy hair.

Purifying the skin

For healthy skin, certain nutrients are essential. Zinc, burdock, succinic acid and oats soothe the skin and improve imperfections.

  • Zinc

Zinc, an essential trace element renowned for its anti-inflammatory properties, is a highly effective ally in soothing skin conditions such as acne and eczema. The “Journal of Drugs in Dermatology” highlighted zinc’s positive effects in regulating sebum production and tissue repair, effectively helping to improve acne and hormonal imperfections. It also acts on hair, as it is essential for hair growth. Research has shown that zinc helps prevent hair loss and promotes scalp health. It is involved in regulating the sebaceous glands, helping to maintain a healthy scalp and prevent dryness.

  • Burdock

This plant is particularly beneficial for skin prone to excess sebum, helping to maintain optimal balance and prevent the formation of pimples and blackheads. Burdock’s antibacterial properties also help purify the skin by eliminating the bacteria responsible for skin eruptions.

Whether applied as a cream ([MY] Emulsion Perfectrice) or integrated into food supplements ([MY] Elixir Détox), burdock offers a natural approach to promoting balance in the skin and skin microbiome.

Due to its anti-inflammatory properties, burdock is often used to soothe conditions such as acne, eczema and rashes. Burdock’s active compounds, notably polyacetylenes and lactones, work synergistically to reduce inflammation, calm redness and promote more balanced skin. Burdock also helps regulate sebum production.

  • Succinic acid

Succinic acid, derived from green biotechnology, is a new active ingredient of particular interest in the treatment of skin imperfections of hormonal origin, such as hormonal acne. Its anti-inflammatory properties have been demonstrated in a number of studies. Hormonal acne is often associated with skin inflammation, so topical application or ingestion of succinic acid could potentially help reduce this inflammation and soothe the skin.

On the other hand, some studies suggest that succinic acid may have regulatory effects on the endocrine system. This could help balance hormones and reduce acne outbreaks associated with hormonal fluctuations. Succinic acid has also shown antibacterial activity in some studies. As acne is often caused by an overgrowth of skin bacteria, the use of succinic acid could potentially help reduce the growth of acne-causing bacteria.

Last but not least, it’s a gentle acid that works to balance the skin’s microbiota: Read more

  • Oats:

Long prized for its nutritive properties in food, but also for its soothing and anti-inflammatory properties. Oats are often used to soothe sensitive, irritated skin. Natural compounds such as colloidal oatmeal act as a protective shield, forming a film on the skin that retains moisture while soothing itching and redness. The carbohydrates present in oats help maintain skin hydration. What’s more, oats contain antioxidants such as tocopherols and beta-glucans, which help neutralize the free radicals responsible for premature skin aging.

The patented oat extract we use in our cosmetics range ([MY] Perfecting Emulsion and [MY] Regenerating Oil) has recognized properties on redness, improving the skin’s bacterial composition, moisturizing, but also on collagen stimulation and skin spots.

The amino acids present in spirulina also help strengthen hair structure, improving hair’s resistance to breakage and brittleness.

In addition, antioxidants such as chlorophyll and phycocyanin present in spirulina help protect hair from damage caused by free radicals. This protection against oxidative stress can help prevent the deterioration of hair structure, promoting healthy, vital hair.

  • Ginkgo biloba

Ginkgo biloba extracts are rich in flavonoid and terpenoid compounds, which have antioxidant properties. These antioxidants can help protect hair follicles from free-radical damage, aiding healthy hair growth. What’s more, Ginkgo biloba is renowned for its vasodilating properties, which means it can improve blood circulation. Improved blood flow to the scalp can stimulate hair follicles, promoting hair growth.

In addition, Ginkgo biloba has anti-inflammatory properties that can help soothe the scalp, reducing irritation and itching. Studies have also suggested that Ginkgo biloba may play a role in hormone regulation.

  • Plant keratin

Plant-based keratin represents a natural, sustainable alternative to keratin of animal origin. This fibrous hair protein is extracted from plant sources such as wheat, corn and soy. Plant keratin helps strengthen hair structure by filling cuticle gaps, which can improve hair strength, reduce split ends and increase elasticity.

Because of its similar composition to natural hair keratin, plant keratin is easily absorbed and can help restore the health of damaged hair. It also promotes hydration by retaining water in hair fibers, helping to prevent dryness and breakage.

By strengthening hair structure and improving hair texture, plant keratin offers a natural solution for healthier, softer, smoother hair.

  • Astaxanthin

A powerful antioxidant carotenoid naturally present in certain microalgae and seafood such as salmon. Its antioxidant power exceeds that of vitamin C and vitamin E, making it an effective shield against the free radicals responsible for premature skin aging. Studies published in theJournal of Dermatological Science indicate that astaxanthin can help improve skin elasticity, reduce wrinkles and promote balanced pigmentation. In addition, this beneficial molecule may support hair health by acting as a protector against UV damage and stimulating scalp blood circulation. It is particularly effective against androgenetic alopecia. Astaxanthin’s anti-inflammatory properties can also help soothe scalp irritations.

  • Rosemary

Rosemary is an aromatic herb, and thanks to its antioxidant properties, rosemary helps neutralize free radicals, helping to prevent cellular damage associated with skin aging. Research in theJournal of Medicinal Food highlights its anti-inflammatory potential, soothing irritation and promoting balanced skin.

For hair, rosemary stimulates blood circulation in the scalp, which can help strengthen hair follicles, enhancing healthy hair growth. What’s more, its natural compounds help combat dandruff and maintain an optimal sebum balance.

  • Brahmi

Brahmi, also known as Bacopa monnieri, is a plant with multiple benefits. Its active compounds, such as saponins and bacosides, work synergistically to promote blood circulation in the scalp. Improved blood circulation can stimulate hair follicles, promoting hair growth. In addition, Brahmi is renowned for its soothing properties, which can help reduce dry or irritated scalp problems. By using Brahmi regularly, not only do you deeply nourish your hair, but you also help maintain a good hormonal balance, a key element for healthy hair.

  • Amla

Amla is a superfood that offers an array of benefits for hair. Rich in vitamin C, antioxidants and essential amino acids, Amla plays a crucial role in hair strengthening, which can help reduce hair loss. Its antimicrobial properties help maintain a healthy scalp by preventing infection and balancing sebum production. Amla also nourishes hair from within, improving its natural shine and texture. Thanks to its ability to stimulate blood circulation to the scalp, it also promotes hair growth.

  • Rice starch

Often overlooked, rice starch is widely used in Asia. This versatile ingredient is renowned for its absorbent properties, helping to regulate excess sebum on the scalp. Using rice starch as a hair care product can also add volume and texture, while making hair more manageable. In addition to its aesthetic properties, rice starch can help strengthen hair by protecting it from external aggressors. Its richness in essential nutrients promotes healthy hair follicles and can help prevent hair breakage.

Microbiome cutanée

Strengthening the skin barrier

In addition to the active ingredients to be favored, it is necessary to protect the skin and mucous membranes, which are already attacked by our lifestyle (pollution, stress…). To achieve this, it’s important to strengthen the bacteria that make up 45% of our skin and scalp. In fact, a balanced skin microbiota, just like a good intestinal microbiota, will prevent the skin from becoming porous, enabling it to better retain the active ingredients it receives, better defend itself against aggression, and prevent the formation of imperfections and redness…

  • Probiotics (ingested) and postbiotics (applied to the skin):

Internally :

Probiotics, beneficial for intestinal health, also exert considerable benefits on the skin barrier. By acting as skin defenders, these micro-organisms promote a balanced skin microbiome, strengthening the skin’s protective barrier against external aggressors. Probiotics help maintain a healthy skin ecosystem by promoting the growth of good bacteria and preventing the proliferation of pathogens. This helps stabilize the skin’s environment, limiting the risk of sensitivity, inflammation and skin reactions.

Probiotics also act on the immune level by modulating skin inflammation. They help reduce excessive reactions, soothing the symptoms of various skin problems such as eczema, acne and psoriasis. By supporting a healthy skin barrier, probiotics help prevent dehydration, dryness and skin irritation.

Discover our complex of prebiotics and probiotics for intimate and intestinal flora.

External use:

Postbiotics are bioactive substances resulting from the action of probiotics (organic acids, enzymes, polysaccharides, peptides and other metabolites produced by probiotics). As far as the skin is concerned, postbiotics can play an important role in maintaining its health and balance:

  1. Reducing inflammation: Some postbiotics have anti-inflammatory properties that can help soothe irritated or inflamed skin.
  2. Reinforcement of the skin barrier: Postbiotics can reinforce the skin’s barrier function, helping to protect against external aggressions and prevent moisture loss.
  3. Balancing the skin microbiome: By nourishing the good bacteria present on the skin, postbiotics can help maintain a balanced skin microbiome, which is essential for healthy skin.
  4. Enhanced wound healing: Some postbiotics can promote wound healing by stimulating the production of growth factors and promoting cell regeneration.
  5. Protection against free radicals: Some postbiotics have antioxidant properties that can help protect the skin against damage caused by free radicals and oxidative stress.

In short, postbiotics promote a healthy skin environment, reduce inflammation, strengthen the skin barrier and promote healing.

Our face care products are formulated with pre- and postbiotics to provide gentle solutions that work in the skin’s direction.

Did you know? Ideally, prebiotics should be added to pre- and postbiotics, to enhance their action and conservation (prebiotics “feed” the good bacteria). Prefer complexes that combine the two!

A little tip for preserving your skin microbiota? Add a drop of our postbiotic face oil to your skin before removing make-up, or as part of your usual skincare routine, to reinforce your skin barrier.


In conclusion

The importance of adopting an In & Out skin care routine lies in the close link between skin and hair health and overall lifestyle habits: there’s no such thing as a miracle cream! Combining quality external skin care with balanced, adequate nutrition promotes better-quality skin and hair. Adopting an appropriate, non-stripping skincare routine is also very important.
