AIMS: To develop an effective sebum control essence to reduce oiliness of skin.
METHODS: The composition of the essence was designed in consideration of different oil control mechanism targets. The skin irritation was assessed in 30 volunteers by a single application close patch test. The efficacy of the essence was evaluated by in vitro experiment, short- and long-term clinical trials with over 60 volunteers.
RESULTS: The results of both in vitro and clinical trials showed that the essence had significant oil control and moisturizing effect, the skin oil content decreased by 21.8% within 8 h and 30.05% after 28 days, which indicated that the essence could achieve rapid and persistent sebum control efficacy. In addition, the essence could relieve the problems of enlarged pores, blackheads and whiteheads in long-term use.
CONCLUSIONS: The essence developed in this study can alleviate the problems of oily skin from many aspects, and achieve an excellent effect in oily skin regulation. It is suitable for a daily application in oily skin regulation.
