Poor skin care before a workout is a major reason for breakouts and acne. Remove all makeup and relieve you face from all the chemicals blocking your pores. Always put moisturizer on. It has zinc which helps against hyperpigmentation and aging. Don’t forget sunscreen – UV rays can break though clouds and will still get you. Don’t forget to clean the equipment before using it. Touching the dirty surfaces with your sweaty bare skin is a recipe for acne because of the microbes that you have just transmitted onto your skin.
