Acne-Ltd III is an excellent acne treatment, after you get out of your shower, keep the face wet and glide the disk over top of the affected area. Hot shower flushing - the skin gets redder by the stimulation of hot showers/baths which is vascular dilation. Overall, it is better to shower in tepid water in the range of 85 to 95 degrees to cool the body and prevent vascular dilation. You may choose to shower with warmer water to open the pores up to clear them or for relaxing, however, remember to begin to lower the temperature to a much lower degree for cooling off to prevent the skin from turning red or to reduce the redness from the prior higher temperature. The cooler water temperature produces vascular constriction.
