This study is intended to look into how effective cosmetics containing 1.5% allantoin and 5% calendula extracts could be in relieving facial porphyrin sebum. To achieve this, a randomized double study was conducted on 16 21-year-old women living in Seoul and Gyeonggi area through January 16 to February 29, 2016. They were divided into a control group (allantoin- and calendula extracts-free) of 8 women, and a allantoin- and calendula extracts group (containing 1.5% allantoin and 5% calendula extracts) of 8 women. The control group, allantoin- and calendula extracts group spent 3 hours at a time to apply each group's toner and cream, and continued for 3 hours after applying the distributed make-up base and grease paint foundation to adhere to their face. They washed their face with cleansing cream provided after 3-hour make-up, and then their facial skin was measured after 20 minutes. The results were as follows. The use of grease paint foundation for 3 hours at a time showed that the control group has a tendency towards a decrease in normal sebum, porphyrin sebum. The moisture content decreased (p<.05). The 1.5% allantoin and 5% calendula group has a tendency towards a decrease in normal sebum. The porphyrin sebum content decreased (p<.05). The moisture content tended to increase. As for the findings stated above, cosmetics containing 1.5% allantoin and 5% calendula extracts help you relieve the skin irritation of stage make-up. Consequently, they reduce porphyrin effectively. Especially, as the oxidized sebum, porphyrin is one of factors that cause trouble by stage make-up, the use of cosmetics suitable for the skin type to reduce porphyrin effectively can minimize facial skin irritation of many people who make-up.
