I started eating sardines (UK Tescos make) a few weeks/months back and i noticed they helped improve the acne scars (i don't like to call them "my acne scars"),but i stopped eating them.I have since started eating them again and i have noticed the acne scars improve again,this was after the 1 day of eating these sardines.

 

What could the ingredients be in these sardines that is making the acne scars look better,if not filling them in?

Sardines are very high in Omega 3 fatty acids, which could potentially be good for your skin.
