I really love freckles. I have red hair and really fair skin, but no freckles. I’m not desperate enough to get up each morning and draw them on, but I came up with an interesting idea: What if you used red henna (the kind they use for mehindi) and applied it to a brush (toothbrush maybe?) and like flick it onto your cheeks *carefully*. Being henna, it would be semi permanent and would stick around for at least a week or so. The coloring would be pretty natural, and the flicking would give it a natural looking, random pattern.
I am considering trying this. Is it completely ridiculous? I don’t have any experience with henna. Would it even work? I would, of course, try out a small area on my arm before spraying my face with it… Thoughts?

People use henna in religious practices or ritual skin painting, and some use it as a fashion statement. I don't think it's ridiculous to use it to create freckles. Some people may have an allergic reaction to henna though. You should definitely test the henna on a small area of your arm to see if you have any allergic reactions before you apply it on your face.
