Purpose: The purpose of this study is to form a new cosmetic market through the development of a composition with high skin permeability after adding omega 3 to Aloe Vera soothing gel products. Research design, data and methodology: In this study, omega-3 fatty acids were added to cosmetic products in the form of soothing gels. By applying nanoparticle technology to rapidly increase the penetration of raw materials into the skin, characteristics related to skin moisture and regeneration were determined. Omega-3 was used as a raw cosmetic material. Then 5% and 15% nanoparticle aqueous products containing omega-3 were prepared. The developed water hydrate was subjected to skin permeability test using artificial skin. Results: 53 hours of artificial transdermal penetration of the developed composition, the ethanol-based omega-3 containing nanoparticle solubilized raw material was about three times higher penetration than the ethanol-based omega-3 containing nanoparticle solubilized raw material. Conclusions: The raw material product (SR-1901) containing 5% of omega-3 nanoparticle water hydrate has skin regeneration ability and pain reduction effect. It can be expected that the skin cosmetics market will be reorganized into a new distribution structure and opportunity through omega-3 supplemented soothing gel cosmetics with improved efficacy than existing cosmetics.

Today, men's appearance is an important part of the global fashion industry, including Korea, with such fashion concepts as the Metrosexual and Ubersexual. Domestic and overseas beauty and cosmetics related organizations are using this phenomenon for marketing and researching to improve the function of cosmetics. The purpose of this study was to investigate the effect of Prunus persica L. Batsch leaf extract on the skin condition after clinical application to male subjects with oily skin to determine the possibility of functional cosmetics utilizing this extract. The cleansing bars were prepared by the MP method and the cleansing packs were prepared using natural ingredients. After 8 weeks of application, moisture, oil, erythema, melanin, pH, elasticity and tactile sensation were measured using MPA5. The results showed that there was a statistically significant difference in T-zone moisture and T-zone oil after using the natural cleansing bar, but there was no significant difference between the two groups for other items. However, the statistically significant changes were found in the individual skin condition change items of the subjects in each group, and it was judged that the two kinds of formulations could be used at the same time to have a higher skin improvement effect. Thus, Prunus persica L. Batsch leaf extract demonstrates potential to be used as a functional cosmetics item.

In this study, we investigated anti-pigmentation effect of a hexapeptide. The peptide significantly reduced melanin contents and inhibited tyrosinase activity in a dose-dependent manner, in which tyrosinase is a key enzyme in melanogenesis. The peptide also significantly reduced the expression levels of tyrosinase (TYR), tyrosinase-related protein 1 (TYRP1) and their upstream transcription factor, microphthalmia-associated transcription factor (MITF). Furthermore, the peptide suppressed the phosphorylation level of cAMP-response element binding protein (CREB), a transcription factor of MITF, and increased the phosphorylation level of extracellular signal-regulated kinase (ERK), a kinase mediates MITF phosphorylation and proteasomal degradation. The peptide significantly inhibited the expression of Rab27A, Melanophilin, and MyosinVa, the components of motor complex involved in intracellular movement of melanosome. These results suggest that Hexapeptide could be used as an effective whitening agent that has inhibitory effect on melanin production and melanosome transport by regulating expression and degradation of MITF in melanocytes.

Objectives: The hazardous heavy metal contents of cosmetics were investigated and the resulting values were compared by type of cosmetics: skin care preparations (SCP), hair preparations (HP), makeup preparations (MP), and eye makeup preparations (EMP). Methods: The hazardous heavy metal contents (Pb, As, Cd, Sb, Ni and Hg) were analyzed for 358 cosmetics products (187 SCP, 82 HP, 56 MP, and 33 EMP). Hg was measured by the amalgamation method, and other hazardous heavy metals were measured by inductively coupled plasma optical emission spectrometer (ICP-OES) after decomposition using the microwave method. Results: The mean contents of Pb, As, Cd, Sb, Ni, and Hg in cosmetics were 0.424, 0.068, 0.024, 0.398, $0.567{\mu}/g$, and Not Detected, respectively. All of the hazardous heavy metals were detected in most products, but below the recommended maximums of the Ministry of Food and Drug Safety. The level of Cd was the lowest at 14.8%, and Sb was the highest at 41.2%. Pb, Sb and Ni showed the highest mean value and detection rate in EMP. As, Cd, and Hg showed the highest in SCP, HP, and MP, respectively. Conclusion: Hazardous heavy metals were detected in most products. In particular, Pb, Sb, and Ni were broadly detected in EMP, meaning more stringent quality control is required.

This paper described the formulation of functional cosmetics and evaluation of anti-wrinkle efficacy in clinical test. Cosmetics were formulated with highly purified $\beta$-carotene obtained from the culture broth of recombinant E.coli cells. Edible oil for solubilizing $\beta$-carotene, vitamine E for long-term storage, detergent/stabilizer (2.0%) for the complete formation of oil/water emulsion, dimethicone (0.35%) for good skin care, and sorbitol for skin moisturizer were also added as ingredients. Physical or chemical degradation of formulated products stored at $0^{\circ}C$, $25^{\circ}C$, or $40^{\circ}C$ was not observed for 60-day testing period. In clinical test, 68% of applicants observed wrinkle decrease after 8-week treatment. This result indicates that newly formulated cosmetics have strong potential for improving wrinkle skin care.
