Ooo I really like this, I think it has brightened my dull skin over the course of using it. I don't think it's done much to my redness and blackheads though. I like the application, it's a little sticky but application is still an ease. I usually wait around 15 minutes for the product to really maximise its potential, some even do it for 30 but I think that's too much. The smell is quite nice, I initially hated it, it smelled tangy but over time it started to smell more citrusy and aromatic for some reason! I don't like how you have to keep it in the fridge, I'm not the biggest fan of having this in the same air and environment as my gross raw meats and stuff, I would like to invest in a mini fridge someday though. Overall, it's a nice vitamin c for an unbeatable price and it doesn't hurt to try it out! I think Vitamin C is one of the top things that people should try out in the routine.
