Le Sérum de Jacynthe, is made with borage, evening primrose, rosehip and sea buckthorn oils, all of which are rich in essential fatty acids (Omega 3 and 6).

Role of Omega-3: Prevents inflammatory reactions and helps maintain skin elasticity.

Role of Omega-6: Improves membrane fluidity and regulates water loss, a primary function of the epidermis.

These essential fatty acids are an integral part of the biochemical and physiological processes of cell regeneration and growth, as well as contribute to the skin’s defense mechanisms. Fatty acids also play an important role in maintaining the skin barrier. They help with water retention in the upper layers of the epidermis and therefore prevent the formation of wrinkles.

A deficiency in essential fatty acids can result in significant water loss and disorganized keratinization (skin aging) from the basal layer all the way to the upper layer, or stratum corneum.


We are so impressed with the power of Seabuckthorn oil CO2 that we now use it in Le Sérum de Jacynthe. One of its greatest assets is its high content of Vitamin A (carotenoids); with over 15 different types of carotenoids, it is a truly exceptional plant-based oil.


Carotenoids are essential for the following functions:

* Regeneration of rough or damaged skin

* Stimulation of cell proliferation

* Collagen production

* Increasing skin elasticity

* Scar formation and healing

* Prevention of wrinkle formation caused by UV radiation (UVA reduces the Vitamin A content in the dermis)

* Slowing cell keratinization (aging) from the basal layer to the stratum corneum.

Our serum can repair sun damage! In addition to seabuckthorn oil, we include, amongst other plant oils, rose essential oil (with its unique vegetable wax and aromatherapy properties), which is certainly the most effective oil for mature and damaged skin. In addition, sandalwood essential oil improves the vitality and tone of the elastin and collagen fibers. It has been used for hundreds of years as an anti-aging treatment in India and Indonesia. We only use pure and natural preservatives, like Vitamin E (California) and Rosemary extract (oleoresin). Our products do not contain any parabens.

Remember, moisturizing the skin is not enough. It must be nourished in order to maintain its integrity as well as rebuild the impermeable barrier that prevents excessive water loss. It appears that water loss is inversely proportional to the linoleic acid (omega 6) content. No other beauty product provides the same effect as this serum. You’ll become addicted, but don't worry, with our pure and natural formula you can safely use as much as you want!
