Thanks to some great suggestions on another thread, I purchased a bunch of samples from Paula's Choice which have just arrived. I am slightly overwhelmed though by the number of choices and have no idea what I am supposed to do with the stickers they sent. Some of the steps are supposed to be done both day and night and they have stickers that say that but then other stickers for the same step for just day or just night. Can anyone help walk me through this? TIA
