  1. Smokers showed a significant decrease in UV spots and improvement in elasticity by cutometry measurement. However, smokers also displayed increased pore count. Values reported are in percentiles, except for UV spots, which are reported as absolute values. Higher percentiles represent an improvement in a parameter. Positive numbers indicate increase, negative numbers indicate decrease. SD, standard deviation.
