Sun allergy symptoms include rashes that look like hives — they appear only when these two conditions concur (for me) : sleep-deprived for three consecutive days and prolonged strong sun exposure …
(go figure why) …
Not sleep-deprived today, no symptoms.
Anyway… it’s still advisable to wear a hypoallergenic sunblock with or without any skin condition. Photo shows a beige-tinted moisturizer SPF50 ( not a luxury — you could get a good hypoallergenic sunblock for less than P100 pesos or less than $2). Always wear a sunblock when going out on a sunny day.
