This study describes methods used in a Korean study to calculate consumer exposure to lipstick and face creams. The average amount applied daily was estimated and compared with data collected by weighing containers before and after use. The data collected was 1.8 to 1.6 times greater than the estimate, so although the survey represented real use patterns, the actual data was more accurate.
