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.

      My favorite

      This serum is the best. I truly live by it. I ran out and nothing is as good for my skin. I am allergic to aloe and all gumš, this is the only serum I can use.

      BEST Vitamin C Serum

      If you only purchase one product to improve your skin, this should be at the top of your list. When I couldn’t get this serum during the company rebrand, I tried another Vit C product. It was good, but I did not see the same results I got with Counter’s product. It truly does even out skin tone, improve texture & minimize sun & blemish damage.

      I LOVE this product!

      I have been using this for years and missed it when it was gone. I tried other Vitamin C serums but none come close to the feel and performance of this one.
