  • 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

Major Allergic Reaction - Had to return :(

So bummed, but I had a terrible allergic reaction. The only new ingredient for me/my skin was Squalane. I had a terrible all over face rash, itchy and bright red skin (looked sunburned) and my skin was raised/inflammed and literally hot to the touch. Then came a breakout and heavy peeling. Fortunately, I used the old sunburn trick of a cold greek yogurt mask and then hydrocortisone and CBD oil to calm and heal my skin over 5-6 days. Sadly I had to return all the products.

Excellent!

I saw my spots start clearing up over 3 weeks. It's a bit pricey but a great product nonetheless.

Too Soon For Feedback Solicitation

I wish Biossance will just slow your roll when soliciting feedback. I just received the product 1.5 weeks ago. You really can’t expect changes to your skin already. Please be less like every other skincare company, as you claim, and be more inline with your values of following the cadence of nature with your natural ingredients. Changes take time, so please don’t solicit for feedback right away. It’s not helpful.

  • What skin issue concerns you most? Uneven Tone & Dark Spots
