It’s a great feeling to know Reviva is being “handed down” from mother to daughter – and even to their granddaughters. And for our next generation of loyal Reviva users we promise to keep delivering the natural skin care people respect and trust.
Because of our commitment to the safe, effective ingredients and formulations, most of our products are suitable for all skin types. And if a particular formula is not advisable for all skin types, we'll say so on the packaging.
