Hinokitiol (Beta-T) is our signature antioxidant found in the Pacific red cedar.

Yes. Riversol products are dermatologist-developed for sensitive skin. Dr. Jason Rivers first created Riversol for patients who struggled to find skincare that delivered results without unnecessary irritation. That same philosophy guides our fragrance-free, paraben-free formulas, made with low-irritant ingredients chosen to support skin comfort.

All Riversol products are produced and tested to the highest standards of tolerance on sensitive skin. They are hypoallergenic, fragrance-free, colorant-free and cruelty free.
