A word of warning, vitamin C degrades in direct sunlight and humidity so don’t keep this stuff in your bathroom unless it’s well ventilated and out of the light. I’ve heard of some people keeping it in their fridge even but I can’t speak to the effectiveness of all that! At least in regards to the sunlight, this stuff is in a dark brown bottle, so that should help filter some of that light out. But if you can, keep it tucked away somewhere just to be on the safe side. At between $20-$25 for 30ml it’s a good value and I heartily recommend you picking up a bottle and giving it a whirl.
OST Original Pure Vitamin C20 Serum gets a full five turtles and a well deserved spot on my daily skin team.
