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.

      Was waiting for this!

      I was waiting for this to come back after the rebranding. So glad it did. Love everything about it but especially my skin!

      Amazing

      Game-changer. I am quite minimal with my skincare and make up routine. I like to keep things simple. After cleansing and moisturizing I just use a little of this serum daily. I have noticed a huge difference in how bright and refreshed my skin looks with using this product routinely. I typically only do mascara and blush as a daily makeup. I don’t like a lot of product on my face, or the heavy feel of foundation. As my skin has matured it can look a little dull, especially in the winter months. Adding this has helped me still feel confident with an ‘almost’ bare face. If you want to give your skin a little boost without a lot of fuss I would highly recommend adding this product into your routine.
