The glyoxal has been used as formaldehyde free DP(durable press) agents in wrinkle free treatment for cotton fabrics. However, the yellowing problem is a disadvantage of DP finishing process for cotton fabrics with glyoxal. In order to improve the whiteness, it was investigated that the effect of coreactant and treatment method with various whitening additives such as STB(sodium tetraborate, $Na_2B_4O_7$), SPB(sodium perborate, $NaBO_3$), SC(sodium chlorite, $NaClO_2$) and SPC(sodium percarbonate, $Na_2CO_3{\cdot}1.5$ $H_2O_2$). The increasing the concentration of whitening additives(STB, SPB, SC and SPC), the whiteness and the strength retention ratio of cotton fabrics were increased but the wrinkle recovery angles were decreased in one bath method. It was not suitable to improve whiteness because the whiteness value is about 60. In the case of SC used two bath method, the whiteness is near 70, which is similar to untreated fabrics, without decreasing of WRA and strength.

This study evaluated the cosmetic effects of a far-infrared hot and cool mask (BBSkinplus) on face skin moisturization, whitening, and wrinkles using a randomized clinical trial. Forty female participants (mean age 47.7 ± 4.6 years) were allocated into the treatment group (BBSkinplus treatment and lotion application twice a day) or the control group (only lotion application twice a day), and moisture, brightness, and wrinkles were measured at 0, 1 and 2 weeks. The average values of each measurement were changed significantly by BBSkinplus treatment compared to the control group. At the 2-week treatment time point, the statistical differences in improvement rates between the two groups were significant at 8.7% vs. 3.9% for moisture (p < 0.01), 0.7% vs. 0.4% for brightness (p < 0.01), and -3.1% vs. 0.0% as Ra and -6.3% vs. 1.5% as R3z for wrinkles (p < 0.05), respectively. No notable complaint was reported regarding any kind of adverse effects such as erythema, itching, or burning. This clinical data support the potential of BBSkinplus as a home beauty device providing moisturizing, whitening, and anti-wrinkle effects on the face.

Objective : The goal of this study is to identify the effects of extract ofGentianae sino-ornata(GSO) on the anti-oxidative activity of skin.For this purpose, several functions of GSO were analyzed in terms of skin-lightening activity and wrinkle improvement. Methods : Cell viability was measured by neutral red (NR) assay, and GSO showed highly efficacy in DPPH radical scavenging activity. The level of tyrosinase and matrix metalloproteinase-1 (MMP-1) in media was analyzed by ELISA kit, and the expressions of p-JNK and p-ERK was measured by Western blot. To elucidate inhibitory effects of GSO on melanin synthesis, I determined the tyrosinase activity and melanin production in B16F10 cells. Results : MMP-1 production in UVB-stimulated HDF cells was inhibited by GSO treatments, and also GSO inhibited protein expression levels of p-JNK and p-ERK. GSO significantly reduced tyrosinase activity and melanin synthesis in B16F10 cells. Conclusions : From these results, GSO appears to be effective on skin elasticity increase, wrinkle improvement, whitening as anti-aging activity.

Collagen is the most abundant animal protein in mammals, accounting for about 30 % of all proteins. It is present in connective tissue and contributes to the structural framework of most organs. The tripeptide (glycineproline-hydroxyproline) with the INCI name Tripeptide-29 is main component of collagen type I. The palmitoyl tripeptide (palmitoyl-glycine-proline-hydroxyproline) with the INCI name Paimitoyi Tripeptide-29 is a synthetic material that was designed as a topical agent to stimulate collagen production. We synthesized the palmitoyl tripeptide as a potential anti-wrinkle compound. This compound has been characterized using HPLC. This compound proved, through in vitro tests, to stimulate collagen production and fibroblast proliferation. These results were very promising, so human studies were subsequently performed. We investigated the skin improvement effect of the palrnitoyl tripeptide on human skin by using non-invasive instruments. We measured physiological effects such as skin wrinkles and elasticity after volunteers applied the cosmetic products for 8 weeks. We observed significant improvement in skin wrinkles and elasticity after use of the cosmetic products for 8 weeks. We concluded that the palmitoyl tripeptide had an anti-aging effect on human facial skin.

It is very important to control the inflammation of the skin because it can develop into diseases such as atopy as well as scarring and aging. In this work, we recently identified the in vitro synthesis of specialized pro-resolving mediators (SPMs) known to control inflammation in the human body and the applicability of cosmetics. Using recombinant protein of lipoxygenase from Glycine max, we succeeded to prepare mixtures of mono- or di-hydroxy DHA named as S-SPMs and used them for in vitro efficacy test. To investigate anti-inflammatory effect of S-SPMs, mRNA level of TNF-α and IL-6 were analyzed. Under UVB exposed condition, expression of both were decreased by S-SPMs treatment. And we observed reduced production of nitric oxide (NO) by S-SPMs application under the condition with diesel particulate matter (DPM). At the same experimental condition, malondialdehyde (MDA) production was decreased by S-SPMs, indicating the inhibitory effect of S-SPMs in lipid peroxidation. In addition, S-SPMs treatment resulted in reduction of matrix metalloproteinases-1 (MMP-1) expression and elevation of procollagen type I synthesis. Together with this, mRNA level of filaggrin and loricrin were increased by S-SPMs, indicating enhancement of skin barrier function. These results demonstrate that S-SPMs is a good candidate to develop as a cosmetic ingredient for anti-inflammation, anti-wrinkle, and improvement of skin barrier function.

Lips have a defect in maintenance of moisture due to their thin layer. As aging progresses, lips lose volume and redness, and become wrinkled. Fat grafting and filler surgery have been used to achieve attractive lips, but little research has been reported to develop better materials to replace the present methods. Recently, a study suggests that the increase of adipocyte number can be enhancing the expansion endogenous fat. In previous study, we identified that the efficacy of Magnolia officinalis bark extract (MOBE) was effective on the induction of adipogenic differentiation. In this study, we confirmed that MOBE enhanced the differentiation of human adipose-derived stem cells on the fat mimic 3D structure built by 3D bioprinting method From further experiments in human, we established a method to quantify the severity of lip wrinkle by measurement of standard deviation of gray value using Image J software. Finally, we found that topical treatment with 1% MOBE formulated lip balm significantly improved the lip wrinkle after using for 12 weeks. In conclusion, these findings suggest that MOBE has great potential, as a cosmetic ingredient, to reduce the lip wrinkle through the effect of promoting adipogenic differentiation.
