The skin condition after dermatological surgery can be changed. As the laser light penetrates into the skin during the procedure it will activate biomolecules which are the cause of the related redness. In addition, it can parch sensitive skin and worsen itching and flaking. The original intention of 'BB cream' is for soothing sensory skin, but not for make-up. The commonly used 'BB cream' is suitable for all skin types and are targeted specially to those who have sensitive and acne-prone skin. It has the advantages of both skin-care and make-up as it improves the skin condition and evens out the skin tone while providing coverage for redness spots and other blemishes. Our study focuses to give the make-up function that naturally correct the brightness and contrast of redness skin, to realize the skin-care function that is effective against sensitive skin.

In order to utilize health food chick bean as a raw material for cosmetics, the skin improvement effect of a mask pack made of chickpea Natto fermented with Bacillus subtilis Natto strain was studied. Powder obtained by lyophilization of chickpea Natto was applied to a facial mask pack as a paste formulation. This Natto pack was applied to subjects in their 50s and 60s to investigate their effect on skin improvement. As the number of treatments of Natto pack increased, the skin was improved and the improvement effect was remarkable after 4 treatments. After four times treatments, moisture content and sebaceous secretion increased by $8.4{\pm}3.6%p$ and $4.0{\pm}2.3%p$, respectively. Skin pores and wrinkles were also decreased by $1.8{\pm}0.3%p$ and $1.8{\pm}0.9%p$, respectively. Skin pigmentation decreased by $1.3{\pm}0.2%p$ and skin tone also increased from 55.2% to 55.9%. These results indicate that Natto product obtained by fermenting chickpea has the effect of improving skin such as moisturizing, pore, wrinkle, pigmentation, sebum secretion and skin tone, and can be used as a raw material for various functional cosmetics.

This study attempted to numerically verify specific effects on skin condition improvement by measuring and comparing changes in skin conditions such as pores, wrinkles, and sebum of LED masks for beauty devices with low output among light sources. 18 healthy women (4 weeks in the control group and 4 weeks in the experimental group) were conducted once a week for 8 weeks. As a result of measuring the skin condition of pores, wrinkles, and sebum, it was confirmed that the skin condition improved significantly as the LED irradiation progressed, and the difference between the groups by measurement period of the experimental group and the control group also showed significant differences in pores, wrinkles, and sebum (p< .001, p<.05). This is meaningful in that it can be presented as clinical information and quantitative data by preparing continuous data in an academic sense by proving the effect of improving the LED mask as a beauty device. It is also suggested that in the future, follow-up studies to prove more effective skin improvement will be conducted.

In this study, Niacinamide (NI) was loaded into solid lipid nanoparticles (SLNs) and skin permeability was evaluated to improve skin permeability of NI, which was a skin whitening substance. NI was able to effectively load within SLN with a double-melting emulsification method, producing stable particles with average particle sizes of 263.30 to 436.93 nm and a zeta potential of -34.77 to -57.60 mV. Artificial skin tissue (SkinEthic^TM RHE) derived from skin keratinocytes derived from human epidermal tissue was used for the skin permeation study of NI. Skin transmittance and deposition experiments of NI confirmed that all SLN formulations improved skin transmittance and deposition rates of NI, approximately 5.4 ~ 7.6 and 9.5 ~ 20.8 improvement over SLN applications. Therefore, SLN manufactured in this study have shown sufficient results to improve the skin permeability of the functional whitening substance, NI.

The aim of the present study was to design ascorbyl glucoside (AG) loaded solid lipid nanoparticles (SLNs) to improve skin penetration of AG. AG loaded SLNs were prepared using double emulsion method. The prepared AG loaded SLNs investigated particle characteristics (particle size, polydispersity index, zeta potential, loading capacity). Skin penetration study was carried out using SkinEthic RHE as one of the reconstructed human epidermis models. The mean particle size and zeta potential of SLNs were 172.65 - 347.19 nm and -22.90 - -41.20 mV, respectively. The loading capacity of AG loaded SLNs demonstrated that loading efficiency and loading amount were ranged from 44.18% to 57.77% and 12.83% to 16.15%, respectively. The results of penetration showed that all SLNs enhanced the skin penetration of AG and the amount of AG from SLNs were approximately 3.7 - 7.4 times higher than that from AG solution. Therefore, AG loaded SLN might be a promising topical drug delivery system.
