Time to clean out the medicine cabinet! Anything 9 months to year after opened should probably go into the trash!! All products have a little pic on them, of an open container, with a date. like 24 months or 12 months. That's how good your product is after you open it. They loose their efficacy. So if your ready for new skin care, I do have curbside pickup! Obagi is a game changer!!!! Pm me for details!
