Re: correcting concealer?
I notice the streaks if I apply too much product. And honestly try it without a brush - get a sponge applicator like the beauty blender. The real techniques one is just as good and much cheaper. I get a much better finish and flawless coverage with it. I don’t even use foundation - just the concealer for my dark circles and maybe a BB cream if I’m going out or something. I swear by that technique. I think use a concealer that works for you but invest in a great blender to seal the deal.
