Powerful but very little product!
I have to start with the one detail I could not get over… how little product there is in this! I can stretchhhh the life of any product but this one was done before I even realized. The tube is deceiving as there is much less in there. Now the product itself is fantastic as is all of MBs products. It felt like it was a very powerful and effective formula but I would have liked to test it for longer. It gave me about 3-3.5 weeks and I was conservative when using it even skipping between days. I say purchase if you can but don’t shell out if you need something longer lasting.

How do you use ALL of the product?
Love this vitamin C formulation. It glides on the skin smoothly and I can see a difference on my skin’s glow and texture. However, how do I use ALL of the product? I have my second balm but still kept the first one incase I read something here that can tell me how to empty it. Also, it’s difficult for me to not overuse this product. I ran out pretty quick (after 4 weeks of daily use). You have to be really mindful when you apply it.

Amazing
Love this vitamin C stick! I have very sensitive skin and this has not caused me to breakout at all. Use it every morning and have noticed my dark spots are vanishing.

Love it!
I loved the texture and finish of this product. It didn't cause any skin irritation. Helped fade some darker spots I had and have noticed a difference more than other vitamin C products I've tried. There's a lot of product left at the end of the tube, use a q-tip to get it all out. About to repurchase my second tube!

Great results!
I have sensitive skin and had very slight breakout at the beginning but I think that's only because your skin purges a bit and has to get used to the product, but no issues since. I feel like the discoloration on my skin has faded and I'm loving it! I use it daily. This is probably the product that runs out the quickest first for me out of the whole line.
