The power of
Hinokitiol.

The signature antioxidant behind Riversol,

derived from Pacific red cedar.

Powerful antioxidant

Helps defend against oxidative stress.

Helps calm skin

Supports calmer-looking skin and visible redness concerns.

Targets uneven pigmentation

Relevant to the pathway involved in excess melanin production.

Naturally antimicrobial

Demonstrates antimicrobial activity in published laboratory research.

Visible redness

Dark spots + uneven tone

Signs of aging

Sensitive skin

Blemish-prone skin

From the forests of the Pacific Northwest.

Hinokitiol, also known as beta-thujaplicin, occurs naturally in select trees in the cypress family, including Pacific red cedar.

Forest

Pacific red cedar (Thuja plicata), an iconic species native to the Pacific Northwest.

Heartwood

Hinokitiol occurs among the natural compounds found in the tree’s heartwood.

Molecule

Beta-thujaplicin, also known as Hinokitiol.

Antioxidant activity

Helps counter oxidative processes associated with environmental stress.

Anti-inflammatory activity

Published research has investigated effects on inflammatory signalling.

Tyrosinase / pigmentation

Research has shown inhibition of tyrosinase activity and melanin biosynthesis.

Antimicrobial activity

Hinokitiol has demonstrated antimicrobial activity in laboratory research.

Finding Hinokitiol wasn’t the hard part.
Formulating with it was.

Hinokitiol can be challenging to formulate into topical skincare. Riversol spent years developing formulations that could successfully incorporate this unusual ingredient into skincare designed for sensitive skin.

Rare ingredient
Difficult chemistry
Years of formulation expertise

That’s why Hinokitiol became a signature of Riversol.

Why a dermatologist chose Hinokitiol.

“The more research I did, the more impressed I was with this unique ingredient and its ability to reduce the look of sunspots and improve skin clarity and texture.”
