He should get these:My son has rosacea and has to wear the mask for 8 to 12 hours per day. He said it is raising hell on his face.

I have these things which help alot with the masks. Since apparently I forget to wear a mask in certain places, I simply wear a mask everytime I'm not in the house and take it off when return to the house. All that Covid needs is a split of a split of a second to enter the body and not wearing a mask when and where you should could increase the risk of getting infected with that thing. That way I don't have to remember to wear a mask before entering a store or inside a public building since its already on the face.
The first helps in making it easier to breathe while wearing a mask because it keeps the mask off the mouth and nostrils. It also makes it easier to talk. It does have a side effect and that is it will cause the nose/mouth areas to produce more oil and its quite noticeable when taking the mask off. Might need certain sheets to blot off the extra oil. The last piece takes the mask bands off the ears, preventing them to feel pain or any discomfort after wearing a mask for a while. They also will tighten the mask on the face, so the first piece comes in handy for keeping the mask off the mouth and nostrils.
I don't know what effect they have on rosacea, but it could help.
