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

Allergic reaction

I have ordered this product twice. In March I ordered it and really liked it. I reordered in August and immediately had an allergic reaction around my eyes and mouth. I had to see a dermatologist to treat the reaction and it took process of elimination and reentry to identify the culprit was this new bottle from august. My eyes looked 40 years older for weeks, they were red and swollen and then became these awful dry patches.

Good dark spot corrector

The serum is okay. It's hydrating but not noticing much improvement in my dark spots. It's also fragrance free which is great for sensitive skin.

BAD REACTION

I got this product back in March and omg the first night I used this serum I woke up with swollen eyes and face! My face was burning and it didn’t go down for a few days. Even after it went down everything that was swollen started to get white **** dots all over and then my face got really dry. I immediately went to the dermatologist and got creams to help out with this allergic reaction. About a month ago I decided “hmm let me give this product one last try before tossing it” so I used the tiniest amount and yet again…woke up with a swollen face. Luckily it wasn’t as bad as the first time around because I used the tiniest amount. I threw away this product and it was a waste of $60 I’m probably never getting back.

Broke Me Out

Let me start by saying I LOVE all the Biossance products I have ever used - and this is just a reaction I had to this particular serum. This was a new one I was trying out. For some reason, it's caused me to break out bad around my mouth and chin area. I came to reviews to see if anyone else had this issue, and seeing that a couple of other people have - which is why I'm sharing my experience. I'm not sure what the difference is between this product and the other Biossance products, but for me, this one didn't work!

So far so great!

I’ve been using the dark spot serum to lighten age spots and brighten skin tone. Working great so far! I do use the lactic acidosis serum a few nights a week, but no other serums.
