How to disguise ugly sore on face,pagetoid Bowens

[whatwouldyoudoifisangoutofkey]

Partner has pagetoid Bowens on side of face .
Has been excised 2 or 3 times but reappears
It's about the size of a 20p piece, raised . It looks awful , it gets crusty and red , scabby.
He's been told this is just the way it is , and is seen regularly by dermatology where his excema is also treated .
My question is , what can he do to disguise it ?
I've searched in vain for low adherent plasters/ dressings but I can't find any that are small enough.

Ask derm if it can be layered, perhaps?

Sorry to be dense , what do you mean layered?
Do you mean put a foundation like make up on it ?

might be typo for lasered?

If it can’t be treated then I would suggest trying a tinted moisturiser. Nothing too matte or thick, not trying to hide it completely, just enough to tone it down so it’s less obvious at first sight. Would he consider that??

Sorry I’m assuming it is scabbed over and dry rather than wet

Thanks @minipie .
I don't think it is dry unfortunately.
I think it needs a small plaster/ dressing ,I can find oblong ones but not round ones that are large enough ( need to be driven slightly bigger than the ones you get after a blood test ) and are low adherent .
