I've been on the hunt for the perfect serum, as I've gotten into skincare this year. I decided to give this one a shot. After cleansing and toning with all my usual products, which have helped my skin. In the evening, I applied two pumps of this to face and neck. It was lightweight, had a strong scent of herbs? No issues in application lightweight, not sticky, glad it had no perfume-y fragrances added. However I woke up the next morning with a face full of whiteheads that sprung up over night (about 6-7), on my chin, upper lip, check and forehead. in the morning I had forgotten I used the new product since I was so tired that night.... So I used it again a few days later. Same thing happened! A lightbulb went off. More whiteheads appeared. BareMinerals serum foundation was a bust for me as well, maybe their line isn't for my skin, I'm very disappointed.
