Sounds like you need to exfoliate. Highly recommend Paula’s Choice 2% bha liquid exfoliant. Use a gentle unscented soap like Dove during this time until the ingrowns resolve. If you sweat a lot you can also use this spray (https://a.co/d/06XDcnxe) to keep infection from occurring.

Not sure if my reply was too much in some way. If so, sorry I’m not the best advisor. I did have a couple more thoughts about mitigations. B.C,, this time of year enteroviruses were the source of most summer colds, per NIH News. Have you tried HOCl? Imu it is effective against more fomite baddies than alcohol including noro which is always a risk at large functions. Amazon sells sprays, gels, and tablets (to make as needed):www.amazon.com/dp/B07T4JKMKDwww.amazon.com/dp/B00GX1RFEYwww.amazon.com/dp/B071ZDZ4SLWHO pdf on HOCl uses. An Air Filter would be worthwhile imo. I think it’s either that or opening the window and blowing air in with a fan. If your brother can’t bring one for you, then I’d try to find out what the objection is to you bringing one. Alternately you could make a crbox with a filter, tape, and box fan https://www.reddit.com/r/crboxes/s/EEFVEqn1ug. A mini-usb fan run from a power bank, put in a cracked window-sill can add a good amount of fresh air. Next to you at night it can add some circulation which helps move air near you to break up aerosols so that any virus dedicates faster.
