If you are anything like me, you spent your formative teen years blasting your face with astringent, drying toners, desperately trying to keep the pimples at bay. Oil was the enemy and I was on a quest to conquer it completely. If you had told me that there was such a thing as a hydrating toner, my teenage mind would have been blown.
I found these serums on Amazon, as I hastily scrolled about trying to find replacements for my dwindling retinol and vitamin C. I liked that the Mad Hippie products had a fairly short ingredients list, and the pricing was about average for 30ml size bottles of product. Only one of these serums, however, has truly impressed me.
