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.

      Fantastic serum

      I have used this serum for years and absolutely love it. When Beautycounter went away for a period, I was forced to try other serums- what a nightmare. I tried several and none of them even came close to the All Bright Vitamin C serum. I even started having breakouts. Luckily Counter arrived and I was able to get this again- within just a couple of days of using the serum my skin turned right around again. Hydrated with no breakouts, and definitely brightens my skin. Will never try another.

      Obvious noticeable results from all my friends!

      I was so happy to be able to start using this vitamin C again! I started using it a couple of years ago and all of my friends who did not even know I was using a different regimen started on how good my skin looked. That was enough for me to realize it did make a noticeable difference

      All clear!

      My face seems clearer after using this Vit. C serum. I have a couple of light age spots and they don't really show much anymore. It is also hydrating.
