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

Wonderful "stuff"

I am very fair and had the pleasure to grow up in Fl. except w-a-y back in "the day" we were not told about the damaging effects of the sun and tanning---- NOW most of us are paying the price for sun damaged skin----this Squalane + Vit C dark spot serum has been introduced to help and lighten our ol' beach damaged skin days. Thank you more than you will ever know for this wonderful serum--IT WORKS !!!!!!!

Dark spot remover works wonders

I rarely take the time to write reviews; however, this product is worth the hype and definitely worth sharing with those of you developing age spots as the years go by. My 57-year old face is in LOVE with the Biossance line of skincare products. The Squalane + Vitamin C Dark Spot Remover is a dream come true. My expectations were not that high when I initially tried the product since so many others from other skin care lines were all talk and no action. After 7 days of use, my brown spots faded by at least 60-70%. They are still there, but once I put on a light foundation powder, they are literally undetectable. This product is a keeper and a daily staple in my skin care routine. LOVE it.

Incredible

This has been the nicest my skin has ever looked in my entire life. I’ve switched 90% of my products to Biossance in the last few months. Most recently added was this vitamin c serum to help clear up dark spots after cystic acne. I actually want to leave the house again. I feel beautiful.
