I have 4 days till my school dance and just randomly broke out all over my face. I have been under tons of stress lately. My friend told me she put lemon juice on her face and it worked in two days. So I was wondering, should I try it? I have oily skin. I need help to clear them and prevent them. should I crush ibuprofen and mix with water and put lemo juice on my face? and also does it work still if lemons aren't fresh? Any other tips would be great to, thanks so much!
