Underneath acne? Whats the best thing to do?

I'm 16 years old and lately i have had awful acne under my skin. Its not to noticeable until i'm out in the sun.. which is all the time. When i'm out in the sun you can really see it and it looks awful (just like bumps under my skin no redness or white heads). I have never had a bad case of this except once. I have tons of cleansers spot on treatments &etc. Normally i do not have this type of acne, my skin is usually has red pimples or white heads. Except on my chin and i've always kind of had underneath bumps since like 8th grade and they never seemed to get better even when using a clinic 7day product which was suppose to break my skin out so it would go away(only worked the first time i used it). Also i have taken a break from all the cleansers and stuff just for the fact my face had got really dry and flaky (like under my nose& near my mouth) it looked awful. However i took some omega-3 fish oil vitamins and also starting putting aveeno lotion and it cleared up. Is there a certain cleanser i should use, vitamins i should take, any home- remedies?
