FORMULATION FACT 01

We formulate our All Bright C Serum with citrus oils Citrus Aurantium Dulcis (Orange) Peel Oil which imparts fragrance while diligently limiting furocoumarins -- natural citrus compounds that can cause skin irritation when exposed to UV light. As always, wear sunscreen as part of a daily healthy skin care regimen.

FORMULATION FACT 02

We chose naturally-derived phytic acid instead of ethylenediaminetetraacetic acid (EDTA) salts designed to improve stability and enhance preservation of our products. Manufacturing EDTA and its salts involves reacting ethylenediamine, a harmful substance associated with reproductive toxicity. Unfortunately, EDTA and its salts may contain trace amounts of this substance. EDTA and its salts are also persistent and can harm the environment.

FORMULATION FACT 03

You’ll never see “Parfum/Fragrance” among our ingredients – full ingredient transparency, always.

      Must Have

      It’s a toss up between this and the Lotus cleanser! I can’t live without either one. When I put the C Serum on my face I feel like it says “ahhhh” . Love it!

      Amazing.

      This was my go to product, the only product that worked at keeping my face bright, acne free, and took away redness. I was devastated when I could no longer get it. I tried other brands but to no avail. My skin was awful. When it came back out again I wasn’t in a position to buy it for myself, and prayed for a way to be able to afford it. My mom got it for me for Christmas and I almost cried. From the first day of use my skin has gone back the way it was in the past. Thank you for bringing it back. I can’t recommend it enough!

      My skin is brighter

      I have noticed how my skin feels softer and looks healthier too. It's not greasy and really looks like I have had the best night sleep.
