This resurfacing retinol serum is perfect at restoring my skins natural barrier.Used over night it gets to works while I sleep.It helps smooth my skin and evens out my blemishes and bumpy skin.I have noticed a big improvement with the texture of my skin when I use this serum.The skin on my forehead gets very rough and bumpy like sandpaper.It feels like a raised rash and can also be seen! Using this resurfacing retinol serum 2-3 times a week has cleared up this rash and keeps it at bay but only as long as I keep up this routine.The minute I stop using this serum my bumpy rough skin returns again.,So this serum will always have a place in my home
