I purchased this last week after looking at my makeup free face in the harsh bathroom light at work. I've used it for three days now. I know it is too soon to see the difference, but I will say that it doesn't seem harsh to my sensitive skin, but will tell you that you will know if you get too close to your eczema. I use it on my nose, cheeks, and chin where I have most of my slight discoloration and acne scars. It mattifies my skin very well, but I use it at night as the last step, but you can use it before your sunscreen in the morning. I sweat too much at work with the A/C out right now to wear makeup or sweat off the vitamin C cream. It is a small tube, but a little goes a long way. It does seem to be geared more towards a spot treatment, but right now I'm using it as a face treatment.
Since I started using this and my Borghese mud masks, purificant and active so far, my skin is super smooth. I am starting my PMS/hormonal phase and have some acne starting to tingle/come up. I'm going to treat those spots as well along with some Southern Magnolia Minerals acne treatment/extracting powder.
