“I received the Retinol serum as a sample last year and tried it for just a few days. I could feel the difference almost immediately. My skin became smoother, the dryness improved, and overall clarity was better. After a few weeks, my pigmentation broke down into smaller parts, and I could see the color had faded a bit. I later purchased the full size and am still loving it. I highly recommend this to anyone with dry, mature skin.”
