10% vitamin C
  • SQUALANE: Derived from sugarcane, it mimics body's natural hydrating oils to provide weightless moisture to deliver active ingredients deep into the skin and prevent overdrying.
  • White Shiitake Mushroom: Synergistic mushroom blend that starts degrading dark spots immediately and continues correcting discoloration with continued use.

All Ingredients:

Water/Aqua/Eau, Glycerin, 3-O-Ethyl Ascorbic Acid, Squalane, Lentinus Edodes Mycelium Extract, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Glycyrrhiza Glabra (Licorice) Root Extract, Sodium Hyaluronate, Citric Acid, Polyacrylate Crosspolymer-6, Acacia Senegal Gum, Xanthan Gum, Sodium Gluconate, Sodium Citrate, Phenoxyethanol, Ethylhexylglycerin.

  • 1Will this get rid of my Melasma/hyperpigmentation/acne scarring?

    With continued use of this serum and sunscreen protection you can see an overall more even skin tone and help fade visible discoloration in the skin.
  • 2Why 10% of L-ascorbic acid/ Vitamin C?

    This is a daily use treatment, a lifestyle serum if you will. 10% has been shown to be an effective and safe amount for daily use. A higher percentage does not equal better or faster results. It is actually possible to have a higher chance of sensitivity when using higher %’s. Even if the % is higher it does not mean that the ingredient is acting on the skin in a stronger manner. I would value stability over higher % for better results and less chance of degradation/irritation. The stability of Vitamin C within a formula is much more important than the percentage.
  • 3Should this be used for spot treat or all over application?

    Results are better if applied all over - our formula only targets excess melanin.
  • 4Is it fragrance free?

    No synthetic fragrance or essential oils are added, so it is completely fragrance free. The ingredients themselves may emit a mild scent that should dissipate after application

love to use, not sure if it does anything

I'm on my 3rd bottle of this. I'm in love with the texture. It's so light and hydrating, no stickiness or smell. I have acne prone, dry skin - it doesn't make my acne flare, and it moisturizes my skin beautifully. But beyond that, I really can't tell if it's doing anything. And it's been 5 months. After this bottle, I want to move on to a tried and true L-ascorbic acid formula instead of this vitamin C derivative. I would rather spend more money on a proven formula than shell out $62 on a hopeful derivative. That's just my personal preference, though. I do still love the experience of this and would use it again if there were more evidence for it.

Magic in a bottle.

I had dark spots around the top and sides of my forehead near my hair line. This product has worked its magic. All the scaly spots are gone. Magic in a bottle.

It works..

I purchased this product back in December, within 4 weeks was extremely pleased with the results. This is the first time I have ever repurchased a skincare product. I am a 70’s baby that over loved the sun in the 80’s.. this stuff made huge difference in my dark spots from those sunny days!

Incredible results!

I have some sun spots on my face that I’ve had for years. I exfoliate regularly, but in mere DAYS I have a visible improvement. Very satisfied with this product. Thank you Biossance!
