"The weather 2tends to be warm with more chance for people being outdoors and more active with more 3sun exposure as well as heat, 4perspiration and 5humidity." 

Dermatologist Dr. Susan Massick with Ohio State University's Wexner Medical Center says sweating can cause two of the most common summer skin problems: 6folliculitis, which is an 7inflammation of hair follicles, and 8acne. Help prevent both by keeping skin clean, especially after a workout or being outdoors in heat. 

"So the most important thing that you can help out with yourself is to decrease the oil production."

This time of year can mean visits to the pool or the beach, which can also affect skin, putting it at risk of becoming dry and 9irritated. Massick says moisturizer can help with rehydration. And if you're 10heading out to the woods, watch for poisonous plants. 

"The best 11rule of thumb 12when it comes to 13poison ivy is try to avoid it as much as possible, wearing long sleeves, especially if you're hiking or if you're working outdoors. And as soon as you come in to go ahead and shower up because it's the oil on the skin that causes the 14rash."

Finally, protect against a skin 15discoloration on the face known as 16melasma by reducing sun exposure. 

Using things like sunscreen, sun protection, hats, scarves, anything that will cover sun exposed areas will help prevent some of this melasma from occurring.
