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

Worth it! Love it! Magic in a bottle!

Hands down best skincare I've EVER used! I've tried MANY and NONE compare to BIOSSANCE! Every single product I've bought I love and has worked so well on my skin. I also love how clean this brand is. This serum is amazing it has cleared my skin and improved it. My acne spots have imporved alot. With all the biossance products I use my skin have never looked this good and its all because of biossance. Other skincare brands have messed up my skin left it a mess so aggravated & inflamed with bad brakouts I felt so depressed about my skin before biossance and I'm just so glad I tried it because it cleared up my skin quickly, calmed it down everything feels amazing on my skin and my skin finally looks and feels healthier than ever. All their products are magic in a bottle! They gave me my confidence back! I can finally leave the house without makeup I don't have to hide my face anymore. If you see this review everywhere it's because I've bought so many products for day and night and everything worked with my skin so I will keep telling everyone about this!

Possibly A Seasonal Product

I had been using this serum for a while and while I didn't notice dramatic results, I did notice over time that spots looked lighter. When I ran out I didn't replace it right away and noticed more spots coming, so I bought more. During that time, I moved from a temperate climate to a cold one and now my skin freaks out when I use the serum... red, patchy, scaly. I have stopped using it but will try it again in the spring since my skin was fine originally.

Got the worst rash/hives of my life

I tried the sample and it gave me the worst rash/hives of my life. My whole face broke out in welts and it's painful and itchy. I immediately threw away the sample and am suffering in pain right now. It's been 48 hours and it still looks like the pictures I attached.

Worked but then caused a bad reaction

The product seemed to work but then after a few weeks I got a rash on my face so I stopped using it. After 6 months I decided to try it again, but the rash appeared on the 3rd day of using it. Big bumps, itchy and irritated. It's definitely from the Biossance so I have to toss it.

It works!

On my second or third bottle of this product and my skin tone has never been more even. I'm extremely fair skinned and have tried everything to lighten the sun spots. What sun spots I still have are so light I'm fairly certain no one notices them but me.
