This powerful and lightweight vitamin C for dark spots serum:
  • Delivers a boost of brightness with 10% vitamin C, while white shiitake mushroom fades dark spots
  • Shows visible brightening instantly, while it works over time to dissolve pigmentation and prevent new discoloration
  • Our unique blend of ingredients is precisely calibrated to not cause irritation like traditional vitamin C serums

This first-of-its-kind serum features a proprietary white shiitake mushroom extract blended with our unique derivative of vitamin C, and delivers quicker, more powerful, longer-lasting results. Not only does it start degrading dark spots immediately, it keeps working every day to prevent new ones from forming.

I received this product for an honest review

Likes: Lightweight, no strong smell, Seems to absorb right away. I also like that I could still feel the product on my skin in the morning. I’ve been using it nightly for approximately two weeks And sadly I haven’t noticed any difference in my dark spots. Will continue to use to see if there is any noticeable difference in the foreseeable future. I’m not sure I would purchase this product for myself.

Lightens my dark spots

I initially got the sample size but loved this so much I bought the full size and incorporated it into my daily morning routine. I haven’t used it for very long yet but I think my dark spots are less noticeable!

Great Results!

After using this serum for less than 2 weeks, the melasma on my cheeks is fading. Over the past couple of years I've tried retinol, vitamin C serum, and tranexamic acid to combat my dark spots with disappointing results. Thanks to Biossance for creating such an amazing skincare product!
