The benefits of mother-of-pearl
The luminous secrets of mother-of-pearl in skincare
Why use mother-of-pearl on the skin?
The benefits of mother-of-pearl are thousands of years old! In fact, the use of mother-of-pearl-based skin cosmetics has its roots in the ancestral beauty traditions of many cultures around the world. Mother-of-pearl, renowned for its shimmering brilliance, offers numerous benefits for the skin.

Age-old benefits: a cosmetic jewel for the skin with exceptional properties
Mother-of-pearl has been used since ancient times. For example, the benefits of mother-of-pearl have been used since ancient Egypt. Known for their sophisticated beauty rituals, they used mother-of-pearl to make skin care products, recognising its moisturising and brightening properties.
The Mayans, for their part, considered mother-of-pearl to be a sacred material and used it to treat skin ailments.
In China, it was ground and incorporated into elixirs designed to prolong youth and vitality.
The Greeks and Romans also used it in their preparations to treat war wounds or as a cosmetic. It was also used to improve skin radiance.
Over the centuries, in the Mediterranean, Oceania and Asia, various cultures have adopted mother-of-pearl as their preferred medicinal and cosmetic ingredient. Today, inspired by these ancient traditions, our brand fuses history, science and the sea to bring you the unrivalled benefits of oyster mother-of-pearl. Immerse yourself in luxury and tradition, and let your skin discover the luminous power of the sea.

Mother-of-pearl: a powerful natural cosmetic ingredient
Rich in essential minerals, notably calcium and conchyoline proteins, it helps to improve the skin’s luminosity and elasticity. Mother-of-pearl also promotes cell regeneration. Mother-of-pearl has many benefits for the skin: it moisturises, strengthens and gives a unique “pearl complexion” effect.
Cosmetics incorporating this precious active ingredient therefore offer a natural and effective solution for sublimating the skin. The mother-of-pearl in Ostrealia cosmetics allows you to benefit from the authentic virtues of this marine element by using upcycled French mother-of-pearl from our oysters.
Natural French cosmetics made from mother-of-pearl
In collaboration with the CNRS and the University of Montpellier, we have discovered an exceptionally high content of porphyrin and ommochrome in the pink pigment of the mother-of-pearl of the Tarbouriech Special oysters. After five years of patented research and development, we’ve combined the best of our mother-of-pearl with marine collagen and sea fennel.
The result? Ostrealia, ua line of natural marine cosmetics with antioxidant, regenerating, moisturising and purifying properties. While other cosmetics incorporate mother-of-pearl, we are unique in using our own oysters, farmed in France, to create mother-of-pearl extracts rich in skin benefits. Among these benefits, the most sought-after are anti-ageing, the treatment of hormonal spots and acne.
What are the benefits of mother-of-pearl for the skin in cosmetics?
Mother-of-pearl is a natural treasure with multiple benefits for the skin, from regeneration and protection to illuminating the complexion. Its richness in nutrients and minerals makes it a precious asset for maintaining healthy, radiant skin.

Cosmetic treasure with repairing properties.
One of the benefits of mother-of-pearl is that it is rich in proteins similar to keratin, which regenerates skin cells. It improves skin elasticity and protects it from ageing thanks to its nutrients and antioxidant properties. What’s more, mother-of-pearl has anti-inflammatory and moisturising properties, making it ideal for sensitive and dry skin.
Anti-ageing benefits of mother-of-pearl in combination
Thanks to its high mineral content (zinc, magnesium, calcium, selenium, manganese), mother-of-pearl slows down the main signs of ageing. As a result, wrinkles, fine lines, loss of radiance and tone, signs of fatigue and pigmentation disorders are reduced. It also promotes healing and provides lasting protection against the effects of ageing.


Combined with sea fennel and marine collagen
Sea fennel, also known as glasswort, is a plant typical of the French coast, growing in sandy soil.
Gorged with iodine and vitamins, loaded with vitamin C, minerals and phenolic acid, it stimulates fibroblasts, firms and regenerates the skin, making it more toned, moisturised and draining (anti-cellulite).
Marine collagen, found in marine fauna and flora and particularly in oyster meat, plumps the skin (making it more elastic), moisturises, tones and protects it from damage.
