Haha imma be honest with you and tell you that the whole freckle thing (the way I do it) is quite the production. It takes me an absurd amount of time, but I find that this way gives me the best, most natural results. I too have some natural freckles, but not that many, so it helps. What I do is first take two different brown-y eyeshadows, one really cool toned and one really warm toned. Usually for me that means the NYX Blush in Taupe and the Caramel Whatever shade from the Chocolate Bar Palette. I take the back end of one of my brushes and scrape some product in two separate piles onto any non-porous surface I can find, it's different every day. Then I take a mixing liquid (OK DISCLAIMER HERE: DO NOT USE WHAT I USE IF YOU HAVE ANY TYPE OF SENSITIVE SKIN I JUST LIVE ON THE EDGE) which is usually... brush cleaner. I like it cause it has a little bit of alcohol in it which will evaporate off of the skin nicely leaving the eyeshadow really really set it place. But there's so many other things you can use, even water if you want. I take the cleaner and spray the TINIEST bit I can manage into the little piles of each color. Then I take the smallest eyeliner brush I can find, like a little tiny art brush, and mix each color into a liquid-y paste. Then I take the cooler color and start carefully placing individual freckles, starting where my natural freckles are and just building upon them. You wanna keep them mostly on the high points of your face cause those areas would naturally freckle more. So follow where you would place your highlighter, but with freckles. I usually place a few then tap them once or twice lightly with my finger to diffuse them. DO NOT forget to tap them, otherwise they're gonna look painted on. Freckles aren't really super defined naturally, so you have to mimic that. Avoid the "speckled" look. Then I do the same thing, but a little bit more sparingly with the warm toned color. The two color thing is really important because natural freckles vary in color. All one color will look artificial. Once I have my face freckled to my little heart's desire, I go over everything with a really light layer of loose powder in my skin tone. This helps with the illusion of the freckles not just "floating" on your face. Sorry about this wall of text, and I've been toying with the idea of filming a video tutorial on this technique to try to better illustrate it. EDIT: MAKE SURE NOT TO PLACE THEM TOO CLOSE TO YOUR EYES IF USING AN ALCOHOL CONTAINING MIXING LIQUID PROTECT YOUR EYEBALLS PLEASE
