I am a boy, and I don't know anything about make-up, but I need to hide some acne blemishes. What should I buy and how to use it? All I know so far by searching from google is that I need a concealer that matches my skin tone or one shade lighter. Is it all that i need?

hmm though i don't suggest a boy using a concealer, you can try Estee Lauder, ideal light, brush on illuminator. its works really good. also go to duty free. there are alot of good quality concealers there. For a simpler and cheaper way, just use white powder and pat it gently to your face giving it an evenly tone.
