Love...and heartbreak

I LOVE this serum!!! My skin looks noticeably healthier and plumper when on days that I apply this in the morning. However, I'm heartbroken that it was a limited edition...please make it a permanent edition!

Great product

I am highly impressed with PHASIC C SERUM 01. My skin tone has improved. My skin is brighter, smoother, softer, and all over improved. I am very glad I bought extra when it was on sale as I seem to be going through it quickly.


After reading all the positive reviews, I wanted to love this product but my skin broke out from this product, so I stopped using it.

Hi Sullivan, We are sorry to hear you experienced a break out with the Phasic C serum. We have rarely heard this, but everyones skin is a bit different. This likely means the product is too heavy (ie. has too much oil) for your skin. We are happy to refund your purchase!

Best Vitamin C for Dry Skin

It was love at use. This is the first vitamin C serum that doesn’t dry out my already dry, sensitive skin. Plus my skin has an extra glow and it still feels hydrated at the end of the day. Loved this so much I snagged some additional bottles to last the rest of the winter. I hope this gets added to the collection permanently!
