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

Seems to be working well!

I was already using the rose vit C serum but wanted to address some melasma. It has only been one week, but I believe it has already begun to lighten! I will update later if more progress occurs.

My skin is glowing

My skin can’t get enough of this serum. I use it morning and night, and I use it even if I’m using another serum. It has improved the daily texture and discoloration I experience and I’m so glad I bought it!

Game changer

I’ve been using Biossance products for a little over two years. When I started I was looking for a new routine with clean products that would help with my acne prone skin. I hit the jackpot. I has actually changed the makeup of my skin. I used to wake up oily and feeling like I needed to wash my face again. With the vitamin c serum, my dark spots have faded and it keeps my face clean and moisturized. I use it in the morning before moisturizer. Buy it. You won’t regret it.

DO NOT RECOMMEND

I broke out in an allergic reaction the next day with HIVES and white spots ALL over my nose and chin and long my jaw. I had to take Allegra and put hydrocortisone on my face. DO NOT BUY
