WHAT IS THIS AMAZING SERUM? I read about this a lot before buying it and figured, i have to try it to see if it works. IT DOES.

Recently I had a crazy hormonal + face mask acne flare up. It was OUT OF CONTROL.
Some reviews had claimed that this helped with lightning dark spots leftover from pimples. It is supposed to restore the skin barrier. And it held true to its promise.

I love the blue colour. This is very watery, and gets absorbed really quickly. Directly after cleansing and before putting ANYTHING else, you have use the dropper and apply it directly on the skin and pat it in. I found that you lose some product if you put it on your palms then pat it in (just don't touch the dropper to your face).
It's incredible how quickly it made a difference. My fine lines have all but disappeared and my skin looks rested, glowy and the acne spots are fading. I am absolutely in love with this serum. I just ordered my second bottle.
This is by far the best anti-aging serum i have discovered. I also got their Midnight Blue calming cream, and OH BOY, together they restored my skin back to health and got rid of imperfections. It looks like i got an expensive facial. Amazing anti-aging line.
