Summer is here and the heat and humidity can have pervasive effects on your skin. Excess heat increases sweat production and the humidity hinders its ability to evaporate away from the skin. This means more oil is available to clog pores and, in turn, acne on the face and body can be exacerbated. Also, extreme heat and humidity can facilitate bacterial infections such as impetigo and fungal infections like athlete's foot or jock itch. While we all try to keep cool in the summer, alcohol based toners and astringents can help clean the skin of excess oil, while washes with benozyl peroxide can help control acne breakouts and infections.
