Ingredients & Formulation

What I want you to know correctly about ceramides.

Many people think of ceramide as a "moisturizing ingredient." That is not right.

Ceramide is the material that builds the skin barrier itself.

What ceramide is doing

The skin's stratum corneum is like bricks for the cells, and the mortar filling the gaps between bricks is the lipid matrix. Ceramide is the main component of that mortar.

When ceramide decreases, gaps open between the bricks. Water escapes. External irritants enter. This is barrier function decline.

Type and concentration matter

There are multiple types of ceramide (Ceramide 1, 2, 3, 6II, etc.). They work in combination for the barrier to function. A single type alone is insufficient.

Concentration also matters. Trace amounts included merely to claim "contains ceramide" produce no effect. Formulation at concentrations capable of actually repairing the barrier is necessary.

What I chose in formulation

Our barrier repair serum contains a ceramide complex, niacinamide, and functional peptides at concentrations sufficient for barrier repair.

Niacinamide promotes ceramide production. Peptides activate the skin's repair signaling. In combination, they produce repair effects that none can achieve alone.

Many products say "contains ceramide." But products with sufficient type variety and concentration are actually very few. When choosing, look at that.
