Definitely Fyrinnae. They have an aloe vera and silica based primer that's totally silicone free and only about $7 for 1 ounce. All the other primers I've tested are mainly silicone and are not good for the skin at all. I have oily skin and am prone to breakouts. This stuff never causes a problem for me. It also doesn't take much product to be effective. Ive tried multiple brands of 'primers', from high end to low end, and this is the best one I've found. It can be used under mineral makeup as well as liquid or cream foundations with no problem. I've also been trying out milk of magnesia as I've heard a few people mention it as being great for oil control. It's also totally silicone free. It does work, for sure. You can get a bottle of it at pretty much any US dollar store. Cheap and effective. One bottle also goes a very long way. Women have been so brainwashed regarding 'primers' in the past few years. Every time I even see the word I cringe bc I know most will wind up believing they absolutely need this in their makeup routine and wind up using the silicone based products, which are not good for the skin. I rarely use even Fyrinnae's primer and my makeup is fine all day. I find that the brush I use for application makes far more of a difference than any 'primer' ever has. I use a Sigma F82 brush which gives a totally smooth, 'airbrushed' type finish. Best investment I ever made. I just ordered another one, actually. That's how much I absolutely love it.
