French supply chain

Expanscience sources its linseed oil from a local partner committed to Conservation Agriculture, a regenerative agriculture method. This hyper-local sourcing guarantees perfect product traceability.

GAÏALINE® is a concentrate of unsaponifiables (rich in phytosterols) from flaxseed oil, obtained by molecular distillation.

Hyper-local & made in France

Our farmer, Ludovic's oil mill is 32km from our production site in Epernon. The linseeds are pressed at his oilmill and then transported directly to our production site.

GAÏALINE® stands out for its dual beneficial impact on skin & hair, but also for its regenerative sourcing and green production method. Derived from flax sourced from an “Au Cœur des Sols” (Conservation Agriculture)-certified farm & oilmill, this active ingredient is both effective and environmentally-friendly.


In-vitro and ex-vivo studies show that GAÏALINE® protects the key markers of the epidermis, the dermo-epidermal junction (DEJ) as well as the dermis (telomeres, keratin 10, filaggrin, hyaluronic acid).
The active ingredient also ensures the integrity of the stratum corneum by boosting ceramides, keratin 14 and collagen 17. Skin feels smooth and even. 

A first clinical study on 48 women (GAÏALINE® vs. placebo) confirms that GAÏALINE®:
-    Strengthens the skin barrier by stimulating the skin’s essential lipids (long ceramides) and maintains its moisture,
-    Reduces the skin micro-relief, class 1 wrinkles and unevenness for a smoother complexion.
GAÏALINE® therefore protects, strengthens and regenerates the barrier function to slow down skin aging. 


A second clinical study was conducted to demonstrate the effectiveness of GAÏALINE®on hair:
-   GAÏALINE® protects damaged hair from daily deterioration (discoloration, blow-drying and heat) by creating a protective sheath


GAÏALINE® is produced using the process of molecular distillation which allows us to extract the most active and precious molecules from oil, the unsaponifiables. This process is an expertise of Laboratoires Expanscience.

Only 1% GAÏALINE® in a formulation is required to provide a natural and effective solution to prevent skin aging and protect hair.
