I had it to but I do not know why

These are blisters! You get them when your skin burns. Same as if you burned yourself on the stove.

Y do they come

Sounds typical of 'waterblisters' appear especially in people who have greasy skin, or use certain tanning oils/sun lotion. Totally harmless

I was told that if you want to protect yourself properly in the sun you need to wear SPF30. Last year on holiday I wore factor 15 and got burnt all over. Uggh I won’t forget that in a hurry! Superdrug are giving 5% of profits from SOLAIT spray lotion bottles to the Teenage Cancer Trust charity. so it might be worth anyone buying sun cream going there to buy it.

so my friend came down from indiana and looks like a burn victim! his skin will never be the same. i told him to take a hot shower, i was wrong in doing so. i think i heard him scream like a girl. help! what does he do for bubbles?
