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

Without an exam specific advice cannot be given. However from your description and young age you most likely have familial fat pad prominence. If this is the case then removing the fat pads from an invisible incision just inside your lower eyelid (transconjunctival approach) can remove or reposition your fat pads so that they no longer are bulging.

Thank you for sharing your question and photo. From the photo, it appears that you have a slight shadow beneath your eyelids (tear trough). For now I would do nothing about it since the problem is so minimal. In the future, if it worsens, fillers can be used to improve the appearance of the eyelids. The bumps (possible milia) can be treated by your local dermatologist. Good luck,

You may want to talk to a doctor to see if fillers may work for you. Maybe talk to them about Belotero, or what other fillers they recommend. this is something that you do not need surgery for unless it is necessary

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.
