If your skin is sun sensitive you might be out of luck with sunscreens containing a chemical called para-aminobenzoic acid, or PABA. When the product is absorbed by the skin, it could cause an annoying allergic reaction or skin rash. Instead, seek out sunscreens without PABA.
9. Bug Bites
Chances are that you’re going to encounter bugs if you go outside this summer. Mosquitoes, ticks and black flies, bite in order to feed on your blood. Stinging insects like bees will cause painful marks at the site of attack, whereas biters, like ants and spiders, will secrete irritating venom that can irritate the skin.
10. Heat Rash
In hot, muggy weather, a heat rash often develops in blisters or red lumps on the skin resulting from excessive sweating and friction (usually from skin or clothing) as sweat ducts are blocked and sweat gets trapped under the skin. The rash will typically clear up in a few hours once you cool down.
Everything from your bath towel to your new sweater can cause skin irritation, typically due to abrasive fabric, clothing dyes, chemical additives, or chafing from clothing that’s too small or too tight against the skin.
Lotions, deodorants, perfumes, and make-up often contain added color, fragrance, and preservative that can cause allergic skin reactions. For instance, many deodorants can cause an irritating rash under your armpits if they contain alpha-hydroxy acid. If you do have a reaction, discontinue use immediately and seek fragrance-free products.
