Objectives : Collagen decrease of Skin appears through various path ways. One of causes may be the Advanced glycation endproducts (AGEs) that combine formation of glucose and protein. The aim of this study was to explore the prevent wrinkle formation of Paeoniae radix (PR) and heated Paeoniae radix (HPR) via AGEs path way. Methods : AGEs formation inhibitory activities of PR and HPR measured using bovine serum albumin, glucose, and fructose. To evaluate the protective effects of PR and HPR in diabetic rats induced with streptozotocin (STZ) and methyl glyoxal (MGO), SD rat were distributed into four groups. Normal rats (Nor), AGEs-induced rats (Con), AGEs-induced rats treated with 100 mg/kg PR(PR), AGEs-induced rats treated with 100 mg/kg HPR (HPR). To induce AGEs, streptozotocin (50 mg/kg) was administered intraperitoneally and after 3 days administrated 100mM methyl glyoxal for 3 weeks. Results : The oral administration of HPR inhibited AGEs in skin tissues compared with PR. The increased reactive oxygen species (ROS) levels in the serum were diminished by HPR treatment. The analyses of kidney and skin tissues proteins indicated that HPR treatment effectively reduced AGEs related protein levels as compared to that by PR treatment. Also, HPR decreased anti-oxidant related protein levels in skin tissues such as catalase, glutathione peroxidase. Moreover, it inhibited the reduction of COL1A2 by decreasing MMP-1. Conclusion : Based on these results, it was suggested that PR and HPR could have Improving effects on wrinkle formation. These evidences provide useful information for the development wrinkle formation treated agent.

To investigate the inhibitory effects of Peonia japonica water extract(PJWE) on skin wrinkle formation, skin wrinkles were induced by both the irradiation of UVB and the application of squalene monohydroperoxide to the backs of hairless mice for 4 weeks. And at the same time experimental materials were applied topically. Wrinkles for the control (C) group were formed as a pattern of deep furrows and thick crests. Whereas wrinkles for the positive control (PC, 0.01% retinoic acid) and experimental(E, PJWE) groups were formed as a pattern of shallow furrows and thin crests, which were similar to that of the normal(N) group. Collagen and elastic fibers in dermis of the PC and E groups were almost intact with a regular arrangement, which were similar to those of the N group. The activity of xanthine oxidase, the free radical generating enzyme, was significantly lower in the E group than the C and PC groups. The activities of superoxide dismutase and catalase, the free radical scavenging enzymes, were much higher in the E group than the C and PC groups and similar to the N group. As for the amount of matrix metalloproteinase-3(MMP-3) expression, PC and E groups were significantly lower than the C group. Therefore, PJWE could be very effective natural herbal material for the inhibition or improvement of wrinkle formation in hairless mice skin.

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.

Postbiotics have various functional effects, such as antioxidant, anti-inflammatory, and anti-obesity. Levilactobacillus brevis BK3, the subject of this study, was derived from lactic acid bacteria isolated from Kimchi, a traditional Korean fermented food. The antioxidant activity of BK3 was confirmed through the measurements of 2,2-diphenyl-1-picryl-hydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and total antioxidant capacity (TAC). The wrinkle improvement effect was validated by assessing elastase inhibitory activity and collagenase inhibitory activity. The intracellular activity was confirmed using human keratinocytes (HaCaT) and human fibroblasts (HFF-1). BK3 protects skin cells from oxidative stress induced by H₂O₂ and reduces intracellular reactive oxygen species (ROS) production. In addition, the expressions of the antioxidant genes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were upregulated. Meanwhile, matrix metalloproteinase-1 (MMP-1) and collagen type I alpha 1 (COL1A1), involved in collagen degradation and synthesis, were significantly regulated. These results suggest the possibility of utilizing BK3 as a functional ingredient with antioxidant and wrinkle-improving effects.

Amino propane sulfonic acid가 피부에 미치는 영향을 non-invasive technique으로 사람의 피부를 이용하여 비교 분석하여 보았다. 측정변수로는 보습, 탄력, 피부색, 피부주름 등 4가지 측면에서 실험을 수행하였다. In vitro culture에서는 fibroblast의 증식은 촉진하였으나 keratinocyte의 중식에는 영향을 주지 못하였다. 또한 raft culture법을 이용해 APSA를 처리하였을 때도 keratinocyte에서 유사한 결과를 얻을 수 있었으므로 in vitro 상에서 표피보다는 진피 부분에서 영향을 주는 것으로 보인다. 임상시험 결과, 피부 보습에는 영향을 주지 않았으며 피부색, 탄력, 잔주름 등이 개선된 효과를 얻을 수 있었다. 특히 New Opticoprofilometry 법인 Visiometer법을 이용하였을 때 피부 주름 변화에 대해 더 유의한 결과를 얻을 수 있었다.

Background Morphological changes that accompany aging, such as wrinkles and skin laxity, are particularly prominent on facial skin. Recently, facial rejuvenation using the hydrofilling effect of hyaluronic acid (HA) filler has been employed for improvement of skin texture. In this study, we studied rejuvenating effects of stabilized HA (Restylane Vital) through direct intradermal injections. Methods A total of 30 female patients underwent a series of procedures on face, including three sessions at intervals of four weeks. A total of 2 mL of Restylane Vital was injected along the whole face using an automatic injector. Improvement of skin surface roughness, elasticity, brightness, moisture, and fine wrinkles was evaluated. Patient satisfaction was evaluated, and pictures of patients were taken at each visit and 6 months after last treatment session. Scoring for each patient was performed by three doctors according in five subjects. Moisture, oil and elasticity were measured before the procedure and before the last treatment in 10 patients. Results The majority of patients (77%) were satisfied with the therapeutic outcomes. Approximately 66% of patients responded that the effects of this procedure persisted for longer than four months, and the majority of patients (77%) wanted to undergo this procedure again and would recommend this procedure to acquaintances. Regarding doctors' evaluation, scores for improvement of skin surface roughness, elasticity, and brightness were significantly higher than those for improvement of moisture and fine wrinkle. Conclusions Intradermal injection of HA can have a rejuvenating effect on dry and tired facial skin, especially in improvement of skin surface roughness.
