I learned about French Skincare maybe a year ago from my dermatologist. Now I can't tell you if it does anything for wrinkles because I'm 26 but I can tell you that since I started using this, my skin has changed. I use La Roche Posay Effaclar because the dermatologist recommended it. There was a toner which I used for a month or so but then I ran out and ended up discovering this. After a few youtube videos and some reviews, I figured I would try it. Yes it water but it's not JUST water. Think of the water that your grandparents or maybe your great grandparents used to drink. It's pure water. Untouched by man. I use this product as a toner before I put on my daytime moisturizer, in the middle of the day when my skin is feeling parched and just recently I used it to set my makeup. I don't use makeup daily, a few times a month maybe. So I heard you could set your makeup using this. I tried it, and had some blot papers in my purse just in case. I finished my makeup around 6pm, I didn't get home until 2 am. NO TOUCH UPS. I know what you're thinking...all night without a touch up? YES. There was virtually no shine on my face. My makeup looked just as good as it did when I put it on. So USE this.
