A NOTE FROM TIFFANY

C-Firma has always been my beloved brightening serum, but as we started selling globally, I had a feeling our customers weren’t getting the freshest possible C-Firma (it takes longer to ship overseas). For l-ascorbic acid to diminish signs of sun damage, fight free radicals, and really brighten the skin, it has to be the right pH, be surrounded by the right ingredients, and be stable. That’s not easy. So we had the idea to deconstruct it. Let the consumer be the mixologist! Now it comes with two vials you mix together. You make it yourself one time only—and it never touches the air, so it’s as fresh as can be. Introducing C-Firma Fresh!
