How I remove these eye bag under the eye? (photos)

Thank you for your question.Looking at your photos it looks like you have tear troughs -areas on the mid face where fat and soft tissue compartments are at the thinnest. It is not really 'eye bag' like in older people which might be due to laxity of soft tissues and drooping of fatty layers.In a young person like you I would not recommend anything as many young people have this problem naturally and you cannot do much about it. Very thin layer of dermal filler sometimes might be used but you probably will find hard to find a doctor willing to do it for such a young person.'Pimple' you describing look like white comedones and multiple milial cysts.See a dermatologist regarding them and I am sure it will be sorted out.
