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

My skin GLOWS

The Squalene + Vitamin C Dark Spot Serum makes my skin radiant! It has significantly helped reduce acne scarring spots on my face and has changed the way my skin looks. This is a holy grail product in my nighttime skincare, along with the Algae Eye Cream!
