Does anyone know any beauty gurus on YouTube with DIY videos and that know a lot about skin. What i mean by that is one that knows the scientific part about beauty or make up and skin. Like Michelle Phan. In many or her videos she talks about the ingredient in stuff that are good for your skin and all that. And BubzBeauty. She knows alot of "scientific" stuff for you sking. Also Secretlifeofabionerd knows alot about skin and whats good for you. I love all these beauty gurus but are there any more gurus like this that u like? Thank youuuuuuu.
