Every summer, small blisters like rice grains appear on my skin;;;;

Hello. I'm writing because I have a question.

I don't know if this is because my skin gets weaker as I get older... or if my constitution changes.

When summer comes, itchy spots increase;;;;

(Representative example: scalp area where the bangs split)

The area around my chin after sweating (itchy and sore;;;)

 

Even a little bit of sunlight on my arms and legs causes itching and tiny, whitehead-like blisters to form...

Fortunately, even if I burst the blisters, they don't ooze out or anything, and if I avoid sunlight, they go away on their own. But this symptom appears every summer...

Is it because the weather is getting hotter as the days go by...?

The area where blisters appear is also increasing;;;

 

In severe cases, the areas where blisters formed merge together and become extremely itchy, so even a little scratching causes

In some cases, the actual pus would come out and it would become so bad that I had to apply ointment all summer long, and it would leave a scar, but after suffering for a few years, I learned to be careful.

It doesn't get worse because I apply sunscreen thoroughly.

The blisters are still there;;;;;

 

Is this some kind of sun allergy or sunburn??

Even though it's a small blister, if it bursts, there's a risk of infection;;;

I sweat and it hurts;;;;

 

Should I go to a dermatologist and get this checked out?

I'm wondering if I should just wear long pants even though it's hot...

 

Is there anyone who experiences the same symptoms??

The blisters are so small that they don't show up well in the photo;;;;

I took a picture as big as I could, can you see it???

 

I have blisters like this on my arms and legs and they itch...

It doesn't burn the skin, but it becomes red;;;
