It being in a powder form means you have to mix it with something. I can see this being an issue if you don’t have anything to mix it with (there are a lot of interactions). The size of the spoon is way too big which can be misleading. This stuff is strong, so please becareful and start with a little bit. I have pretty resilient skin and even I found the stinging pretty bad for the first few uses.

This is one of the only products I’ve used where my skin has almosy instantly looked better. Obviously it hasn’t fixed everything in one day, but my skin feels a lot more even just after a few uses. Its powder form makes its shelf life significantly longer (6M) which is appriciated. Also it is quite cheap for vitamin C.
