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.

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

Skin that looks brighter and feels softer

I started using the serum on my vacation to Palm Springs a few months ago. I use it once in conjunction with the Biossance cleanser first, then serum, and then the face cream once in the morning and at night before going to bed. My skin feels noticeable softer after a few days. On my Zoom calls, I can also see a difference. My skin is noticeably brighter.

My FAVORITE skincare product

I never leave reviews for products because everyone is different, our skin has different needs so my experience will be different from others’ but this product deserves another 5 star review. I like to compare my skin to terrain. It’s dry in some places, bumpy in others, uneven, a little swampy in some places lol. Generally one product might fix one of these issues but exacerbate the others. However this resolves all of my issues. I’ve never had calm, even, smooth, glowing skin in my entire life until now. And the best part is it quickly lightens the annoying red marks that I seem to easily get from breakouts. For reference, I am 38. Very fair, sensitive, and often dry skin. Please don’t stop making this. I need it so I can look my best for the next 40+ years!
