Amazing product

I have struggled with having small flesh colored bumps on my forehead for so long. I’ve tried everything in the book and after just one night I saw a dramatic decrease in their appearance. Top picture was the morning after using this product and the bottom was the night I used it.

Amazing for oily skin!!

I have been using the night serum daily for two weeks now and have noticed huge improvements with the texture of my skin. Before this product, I used masks and peeling exfoliants that could be applied a maximum of 1-2 times a week. However, these products were not effective in getting rid of my dead skin cells for more than 2 days or smoothing out my skin. Since this Biossance night serum can be used every night without causing irritation, the dead skin cells on my face don’t have to pile for a week before the next treatment like I had to do with past products. Also, in the morning I have noted that the night serum has smoothed out bumpy parts on my cheeks, forehead, and jawline. The night serum has a cream consistency that feels light when you apply it to your face and not greasy or sticky. I put 1-2 pumps of the serum on my face & neck after my eye cream but before my moisturizer daily at night. Lastly, I have very oily skin with huge pores across my nose & cheeks and I was a bit on edge to use this product due to squalane. However, after doing my research, squalane is actually known to help with oil production since it mimics our own natural oils. My nose has been producing less oil and doesn’t have a shiny look to it as before. I highly recommend this product and I would likely purchase this product in the future. *I received this product complimentary from Biossance but my opinion is my own.

Love the serum! Don't love the bottle...

This serum is amazing. I use it every other night under my Biossance Squalane & Vitamin C Rose Oil. The combination of the two is the best thing to ever happen to my skin. BUT...I don't love the bottle this serum comes in. Whatever coating is on the twistable cap of the bottle doesn't hold well. Every time I use it I get little gold specs all over my hands because it's peeling off and it drives me crazy. I love everything else about the product though!

Hi Emily, We appreciate you taking the time to provide us feedback. This is something other customers experienced before too and we heard you! We worked on a new packaging that is now getting delivered to our warehouse and Sephora's, so new orders will be receiving the improved bottles. Thanks, Biossance Team

Lactic acid serum

I love this product!!! First product I have bought that actually works over night! It really helps even out my skin tone and helps my redness on my cheeks. The only down side is the bottle. It looks pretty but after using it a few times the gold top starts to flake off and then it gets all over my hands when I apply the serum and then my face looks like a disco ball! I really want to keep buying this product so I hope they change this bottle

Love this product!

I’ve tried many products that do nothing for my face. I have pcos; which makes my hormones unbalanced and have cystic acne 3 weeks out of the month. I hate going anywhere without makeup on, to hide all of the blemishes and uneven skin tone. I purchased the sample size after I read reviews, and love it! I really love how smooth my face feels, helped with my uneven skins tone and keeps my cystic acne in check. Needless to say I purchased the full size. Shipping and ordering has been super quick and arrived within days. I have never tried a product that has worked so well on my face! Definitely a game changer!
