Apparently it can. Sun rash normally appears white northern European type skin,but I seem to get it anyway, and I have a Middle Eastern complexion. Treating is is really hard as it spreads, but I find that by keeping my skin oily in dry conditions spread is prevented. I also find that AC (or aeroplanes) after sun really triggers the rash. For some reason polyester does too. For me I don't get the rash if I apply sunblock cream before solar exposure. For treatment baby nappyrash cream is best. Hydrocortizone works well, but the rash comes back worse next time. Oh yes, and avoid more sun.
