Expensive, but totally worth every penny.

I use this every night after cleansing and before my cream. After the first 3 months my skin tags have flattened and my skin is glowing. This one ounce jar lasts me about 2 months so I am using easily 6 a year.
And it's totally worth it to look and feel this good.

Using with Enzyme Cleanser, Activating Mist and Nourishing Moisturizer. The system is amazing, but this is the key that makes it all work.

Must have

Lightened up my acne scarring SO quick. And the glow is unreal.

Love this stuff...really improved my skin. AAA+++!!!

I got this for my mom and her skin started looking better after a few weeks. I decided to add this along with Stemfactor and my skin has never looked so good! I use a very thin amount and my skin is firmer and the bags under my eyes appear tighter, yet don't "feel" tight/dry. I had 3 or 4 tiny bumps on my forehead that are flattening. I thought the redness at the creases on either side of my nose was normal, but after using this I no longer have to conceal it with makeup. Actually, I've gone all week with only eyeliner, lipgloss, and sunscreen when necessary!
