Buying less, didn't finish any books unfortunately. Finally using cosmetic(s) I had around for a long time.
I had my standard (200ml) bottle since December, but didn't really use it for few months. Then I started to use it, but I used so little on a pad that it barely made a difference. Since I got advice to apply it directly with hands changed everything... I started to use more but I didn't waste as much of it as before (on pads). I finally started to see the effects, one week was enough to help me a lot - my skin is getting more clear. Despite it being alcohol based it didn't dry out my skin that much, even if I skipped moisturizer at night. With moisturizer there's no difference either. When I'm doing my makeup I put my moisturizer soon after it and I swear my face is less oily during the day and I didn't have to reapply powder or even use blotting papers as much as I did. I'm really satisfied with it and in the end I didn't waste my money.
