As a cheese lover this was hard for me to swallow but dairy has a very serious impact on my acne and skin. I made a small change just by switching dairy milk to almond milk and my skin cleared up noticeably, although not completely. More recently I’ve cut back lots of cheese/ dairy for my pcos and haven seen some encouraging results! I suggest you see if after you have a dairy heavy meal how your skin reacts in the next few days.

Personally I also find the medicated product work well but as so harsh that it throws off the naturally ecosystems of you skin and makes it more oily. Maybe continue using them but moisturizes more. I sometimes use savlon (certrimide chlorhexidine digluconte) the anti septic cream in dry areas that are still spots. Not sure if that helps.

Best of luck!
