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

Not for sensitive skin

I just started using biossance about 2 months ago after a struggle with dermatitis and acne that flared up during the pandemic and their other products got it under control finally! I was excited to try this to try and fade the hyperpigmentation left behind from my flare up but after a few days of adding this into my routine it sparked my dermatitis to flare up again :( I was so upset because now my chin/mouth area is very inflamed again but I think just going back to my original biossance regimen should fix it but just wanted to warn others with sensitive skin that this might not be for you

Horrible reaction!!

I started using this product a couple weeks ago and noticed I woke up very itchy on face and neck with eczema like patches. My whole face is very dry still and peeling with itchy patches here and there. I have used it a total of 5 times in hopes that my skin would shed and look better and brighter but I couldn’t stand the side effects. I normally do not have sensitive skin so this was a shock and disappointing because of all the amazing reviews. I love this company and use multiple other products from them but this was not a winner.

Good Vitamin C with room for improvement

Let’s start with the fact this is a very good vitamin C. It’s a stable form. Less sensitive to air and light and comes in a good container for protecting the product. I do wish, for the price, they would up the content. 10% just really isn’t enough for most people to see dramatic results. From numerous studies I’ve read it seems like 15% is the sweet spot. I don’t mind this much personally because I’m really just using it as a great antioxidant in my skincare routine and it feels really really nice. Folks with more serous issues might need to find a higher concentration. Lastly can I just say how sick I am of skincare companies gendering all of their products. News flash people. These products are gender neutral but they insist on all their studies being done on women and marketing ONLY to women. What happened to gender inclusiveness? I expect more from a company. Especially from the Bay Area.
