The customized cosmetics preparation management qualification system was implemented in March 2020, and it served to create jobs by developing professionals and vitalizing the cosmetics business. However, various problems such as high examination fees, suitability of questions, and utilization in industries are emerging. This paper attempts to prevent disputes that the system can cause and suggest ways to improve it by researching customized cosmetics, the industry status, and comparing foreign cosmetics laws. There is a kind of opinion that laws should be eased for this industry and the other opinion that expertise is necessary in this field because of safety. The system now has adverse effects due to a failure to adjust the difficulty of the exam. Cosmetics are not prescription-based, so they are routinely used. However, some toxic ingredients can cause side effects if they do not conform with certain standards. Also, it is difficult for a case to lead to lawsuits because most consumer damages related to cosmetics are individual. In addition, as e-commerce develops, there is a growing possibility of seeing more consumer damages. If safety and distribution issues, which experts are concerned about, escalate, the private dispute settlement system (among the ADR systems) should be activated as a resolution method.

Recently, the importance of individual skin characteristic is emphasized for customized beauty products. There are many studies on the concept of the syndrome differentiation, related to individual cosmetics in Korean Medicine. However, skin characteristic according to Yin deficiency syndrome (YDS), which is associated with aging, are yet to be clarified. The objective of this study was to evaluate the skin characteristic and questionnaire of female with YDS compare to with non-YDS. 218 healthy females between 40 and 59 years of age were assessed for the skin hydration, elasticity, brightness (L^* value), redness (a^* value), pore, pigmentation, wrinkle, and sebum by Corneometerr^®, Cutometerr^®, and Janus lll. Independent t-test showed lower hydration, lower elasticity, and higher redness in the YDS group compared to the non-YDS group (all p < 0.05). There was significant difference on the facial fever, insomnia, decreased amount of urine, and skin sensitive checklist. These results suggested that using the questionnaire associated with YDS and skin characteristic could separate skin types and apply to customized beauty products.

Customized cosmetics are continuously mentioned as a trend in the cosmetics industry to respond to the recent rapid changes in the social environment and pursue individuality and diversity. Accordingly, four types of liposome essence corresponding to skin types were prepared by varying the ratio of liposome formulation and essence formulation as a customized cosmetic base that can be easily mixed and applied at the workplace. The volatilization residues of four types of liposome essence were measured and the nanoparticle size, polydispersity index, zeta potential and viscosity according to time for 90 d were measured, and Turbiscan was measured as a method for evaluating the stability of a colloidal dispersion system. In addition, a simple usability evaluation was performed for four types of liposome essence corresponding to the skin type. As a result, the amount of volatile residue in the four types of liposome essence was increased in dry products rather than oily ones, and the particle size showed a tendency to increase with time in the range of 165 to 175 nm, increasing up to 31.5%, and the polydispersity index was 0.23 to 0.26. There was little change with time, and the zeta potential was -74 to -72 mV, showing a slight decrease with time, but there was little change to the extent of a maximum decrease of 14.0%. Viscosity showed a decreasing trend with time in the range of 2,580 ~ 3,290 cps, showing a maximum decrease of 17.5%. In the turbiscan measurement, all of the turbiscan stability index, a measure of stability, were less than 1.0, indicating dispersion stability. In the overall simple usability satisfaction evaluation for skin types (6 points), products for oily skin (5.33 ± 0.75 points) > products for medium dry skin (5.13 ± 0.95 points) > products for dry skin (5.03 ± 0.96 points) > products for oily skin (4.80 ± 1.04 points) points) were evaluated in order. The four types of liposome essence corresponding to skin types with different ratios of liposome formulation and essence formulation were physically stable, and the possibility of application as a customized cosmetic base according to skin type was confirmed.

Customized cosmetics are continuously mentioned as cosmetics in response to changes in the social environment and trends that emphasize individuality. Therefore, in this study, four types of nanoemulsion ampoules corresponding to skin types were prepared by different ratios of nanoemulsion formulation and ampoule formulation, and the applicability as a customized cosmetic base was checked. Particle size, polydispersity index, zeta potential, and viscosity according to time for 90 d were measured for four nanoemulsion ampoules with different volatile residues, and turbiscan was measured as a method for evaluating the stability of a colloidal dispersion system. Finally, human usability satisfaction was evaluated. As a result, it was confirmed that four kinds of nanoemulsion ampoules had a higher amount of volatile residue in the dry skin test product than in the oily skin test product. The pH was in the range of 6.41 to 6.88, and the particle size was in the range of 170 to 174 nm, and the change after 90 d was within 1.2% of the maximum, and there was no specificity in particle size stability. It was confirmed that the polydispersity index was almost constant, and showed a particle size distribution close to monodispersity by showing a change within a value smaller than 0.21 in all test products. The zeta potential was initially -63 mV or more for all four types of test products, and although it showed a slight decrease with time, there was little change to the extent of a maximum decrease of 2.5%. Viscosity was initially in the range of 4,100 to 5,100 cps and showed a decreasing trend with time, showing a maximum decrease of 37.7%. In the turbiscan measurement, the turbiscan stability index, a measure of stability, was all below 1.0, indicating dispersion stability. In the usability satisfaction evaluation (6 points) of 4 nanoemulsion ampoules corresponding to skin type, oily skin product (5.42 ± 0.67 points) > neutral oily skin product (5.36 ± 0.67 points) > neutral dry skin product (5.15 ± 0.69 point) > dry skin product (4.75 ± 0.75 points) in the order of evaluation. Four types of nanoemulsion ampoules are physically stable and have confirmed their applicability as a customized cosmetic base according to skin type, and are expected to expand in various ways.
