From John Kitchen, Kettering, Northamptonshire, UK
On the subject of acne, rather than lotions or medicines, I find the easiest way to improve skin is to exercise for about 30 minutes non-stop and work up a good sweat. Then sit in a steam room for as long as you can with a bottle of water for rehydration. My skin improves in no time. It became awful during covid-19 lockdowns, but once I returned to the gym, it cleared up very quickly (18 November, p 36).
