Hi! I'm using lemon only for spot treatment. I'm using it on my pimple, but not all over my face. It has stingy sensation but I kinda like it ðŸ˜‚ because I feel it works. I use with cutted cotton pads and put the juice in. I leave it until it dries. At tomorrow my pimple just dry â¤ Maybe some people said It's too acidic, but I'm not often using this treatment.
