I wanted to “add on” to my freckles and after trying several methods landed on Mihenna! I found that I had to leave it on at least 3-4 hours so overnight or at least late evening into night worked best for me. They gradually darken and I’ve gotten a lot of compliments on my cute little freckles that no one ever noticed before. So far they have lasted at least a week and so fun and easy to dot on!
