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

Wonderful

I love this serum. I first received a sample from Sephora and since then I have been hooked. It is quite pricey so I can only really afford to purchase during sales however this serum is worth it. Sinks into my skin quickly and leaves an amazing vitamin C glow that is hard to beat ( I have tried numerous vitamin c serums). I also find it to be very moisturising. Cannot recommend it enough.

So smooth!

Love the texture of this serum and how it feels on my skin. My skin absorbs it very nicely and I feel pampered whenever I use it. Been using it for about 2 weeks and see my dark spots starting to fade.

Hopeful

I purchased this in hopes of clearing dark spots on my face, neck and chest. So far, I nothing has truly faded. I even ordered a second bottle and am hoping that longer term use will yield results as the product is not cheap. So, hopeful I will remain!

Made my melasma darker :(

I had high hopes for this product and have been using it religiously for a few months. My melasma on my forehead and cheeks is now worse after using it vs lighter. This may be good for dark spots caused by acne and picking, but if you’re looking for a melasma fix this isn’t it.
