Reviva Labs has been creating superior natural skin care for nearly half a century – but it's just getting started. With over 45 years, it continues its commitment to being a leader in the natural skin care industry, creating unsurpassed natural skin care that its founder, Stephen Strassler, would be proud of. As safety and efficacy is the brand's primary concern, it goes through an extensive review and testing process before introducing a new product. Skin sensitivity, stability, effectiveness, and potency are all examined and scrutinized over the course of months (or years) during development. You can only be sure that the brand uses the highest-quality ingredients that are both safe and effective for almost all skin types.
