Take a deeper look

Color taken seriously.

  • Salicylic acid was discovered from studying the phytochemical profile of willow bark (different than willowherb but still interesting) - In 1828, Rafael Piria, an Italian chemist, successfully isolated salicin from the bark of the white willow tree, which upon metabolization is converted to salicylic acid. With subsequent research, salicylic acid’s keratolytic (exfoliating) properties were discovered when scientists experimented with its topical application on hyperkeratotic conditions (warts, calluses, etc.) and observed its ability to break down and dissolve excess keratin, resulting in the exfoliation of dead skin cells.

  • Synergistic to this keratolytic activity, the antimicrobial activity of flavonoids (a class of polyphenolic bioactives found in willowherb) was also discovered between the 19th and 20th centuries when there were major breakthroughs in the field of organic chemistry. It was found that flavonoids act as detoxifying agents that inactivate microbial adhesion to skin cells and disrupt bacterial membranes, providing a secondary cleansing action

Gentle and Effective!

Really enjoyed using this product. I am not someone with a large scale face routine which I am trying to adopt a process that works for me now that I get older. Sometimes I worry that trying new products or different types of acids or serums will irritate my skin. But this has been wonderful to add to my routine! It is nice and gentle and not overpowering. While still being effective. My skin feels smoother, tighter and toned. I had blemishes from some scarring (i am a terrible face picker) and feel this has started to help with toning and balancing my skin. Definitely recommend. Good value. I received this product in exchange for an honest review and after using this profuct I would definitely purchase on my own!
