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.

  • 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.
  • 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.
  • Results are better if applied all over - our formula only targets excess melanin.
  • 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

Great product

I've been using this product regularly for a few weeks, and I'm very happy. I was looking for a product that goes on easily, smells great and improves my skin tone and texture. I'm very happy with it. I would definitely recommend this product.

Great overall serum for everyday

Of all the Biossance products this is the one I don’t live without. I use it every morning before makeup to lightly hydrate and take care of fading spots from acne and general ruddiness. It has never broke me out or caused and inflammation.

Burned my face !

Unfortunately this burned my face and caused some serious red bumps and patches with dry and itchy skin that I’m still having to slather with moisturizer days after.

Worth trying, silky texture

Easy to apply. Melts in to your skin. Layers really well under moisturizer. Been using about a month. Skin looks better, its softer and less splotchy(dark spots are a bit less dark). I'm going to keep using & hopefully my dark spots at least fade, if not go away entirely.

Allergic to the products

Unfortunately I am highly allergic to this line. My face broke out with red, itchy, scaly patches.
