I’ve used a retinol product from another brand, but it was at a much lower dosage. I thought I was ready to graduate from that lower dosage, so after lots of research I selected this retinol. I have to admittedly say that it did cause some slight irritation on my neck, but on my face, I was fine. I am only using it once a week – and I am seeing a pretty quick results! Within two or three weeks, my skin looks noticeably more radiant and smooth.
