So I've been making a c serum but I'm wondering how to clean the bottle in the middle. Just rinse with distilled water?
Yes, I do! Fresher = more potent. Also cheaper. Also less nasty chemicals and preservatives. The factory-made stuff has already been sitting on somebody's shelf for who knows how long, so it's on its way to oxidation before you even get it. They charge way too much for the amount of raw materials in it. Once you have made your own and seen how effective it is, you will wonder why anyone even bothers to buy the brand name stuff. It isn't brain surgery....anyone can make a simple serum.Do you guys really feel that homemade serums are the best?
