Take a deeper look

Color taken seriously.

  • Xanthophyll is a class of light-harvesting, highly polar bioactives found in marigolds that gives the flower (and the serum) its yellow-orange color. With up to 65 times higher SOAC (singlet oxygen antioxidant capacity) than ascorbic acid, it shields vitamin C against degradation by bonding with reactive oxygen in the presence of air and light.

  • Defined by its coloring function, the name ‘xanthophyll’ is made up of the Greek words, xanthos (yellow) and phyllon (leaf). What’s interesting is that its stabilizing property is not different from its coloring function. The former is the result of the latter - sunlight is made up of the 7 colors of the rainbow. The sun’s UV rays or ultraviolet radiation, known for its role in causing free radical damage, lies on the blue-violet end of the spectrum. Xanthophylls appear yellow-orange because they absorb sunlight (all 7 colors) and capture the UV radiation (the blue-violet rays) to only reflect the yellow-orange rays, thus giving the flower (and the serum) its yellow-orange color..

Leaves skin soft and glowy

I received the Wildfleur Vitamin C serum for free in exchange for my honest review. I absolutely loved this serum! It feels and looks like an oil but it isn't greasy at all. It leaves my skin feeling very moisturized and gives it a healthy glow. I haven't noticed any brightening effects but that might take longer than a few weeks to see. I was very surprised to see how affordable this product is and would definitely purchase it myself just for the moisturizing effects.
