Aging in humans is inexorable and inescapable. The progressive decrease of physiological capacity and the reduction of the ability to cope with environmental stresses lead to increased susceptibility and vulnerability to human disease. Recently, in the cosmetic industry, many researchers have paid considerable attention to delaying or improving the symptoms of skin aging. Since the early 1990`s, there have been various challenges in developing cosmeceutical products which have strong anti-aging effects, and this has been an important issue in the cosmetic industry. Meanwhile, development of anti-aging cosmetics supported by biochemical activities in the skin has been researched. Castanea crenata inner Shell solvent extracts were investigated for anti-wrinkle and whitening effects, in order to apply it as a functional ingredient for cosmetic products. For anti-wrinkle effect, elastase inhibition activity of Castanea crenata inner shell acetone extract (CA) was 51.0% at a concentration of 100 ug/ml. The collagenase inhibition activity of CA and Castanea crenata inner shell ethanol extract (CE) was 96.4%, 94.3% at a concentration of 50 ug/ml. The tyrosinase inhibitory effect, which is related to skin-whitening, was 47.2% and 45.8% in CA and CE at a concentration of 500 ug/ml. All these results suggest that Castanea crenata inner shell can be effectively used as a cosmeceutical ingredient for the prevention of wrinkles.

The human skins had a lot of changes as aging. The synthesis of collagens and elastic fibers were reduced and the expression of matrix metalloproteinase (MMPs) was increased in the dermis. These changes have been known to be responsible for skin wrinkle formation. In this study, we tried to develop pre-indicator of inner skin aging, and investigated the effect of the cream product containing Gynostemma pentaphyllum gypenoside fraction (Gynostemma pentaphyllum gypenoside cream). 21 ~ 34 years old 52 Korean female volunteers without crow's feet were chosen for this clinical study. The starting point of inner skin aging was confirmed through dermal density measurement, even though outside skin wrinkles were not observed. In addition, 4 and 8 weeks treatment of G. pentaphyllum gypenoside cream significantly increased age-related reduction of dermal density. These results suggest that the evaluation of dermal density can be used as pre-indicator of skin aging. Furthermore, G. pentaphyllum gypenoside fraction is a potential anti-wrinkle agent for prevention and treatment of skin aging.

Many researchers revealed that collagen contribute to maintaining the skin’s elasticity and inhibit wrinkling of skin. Korean native cattle (Hanwoo) bone (leg bone, foot and tail) infusion contains the various inorganic materials, collagen and chondroitin sulfate. All of this, a large quantity of collagen is included in Hanwoo infusion. Therefore, this study emphasized on the effects of collagen in the Hanwoo bone infusion. For the first time, Hanwoo bone infusions were directly added to the media of Human Dermal Fibroblast (NHDF-c) to test anti-aging effects. First, it was identified that growth rate of skin fibroblast was increased. Furthermore, the Hanwoo bone infusion increased a 50% of fibroblast collagen synthesis. Also, suppression of skin fibroblast aging was confirmed by treatment Hanwoo bone infusion. In conclusion, this study demonstrates the effects of infusion made from Hanwoo leg bone, foot and tail on anti-aging, wrinkle inhibiting and skin fibroblast elasticity maintaining. Therefore, this study identified that traditional infusion has effects that are good for skin elasticity.

Hyaluronic acid(HA) is a naturally occurring mucopolysaccharide composed of the repeating disaccharide unit of D-glucuronic acid and N-acetyl-D-glucosamine. HA exists as a high molecular weight polymer in the extracellular matrix of many tissues in the body. HA has been widely used not only for osteoarthritis and ophthalmology but also for cosmetics for skin care. Recently HA has drawin much attention for use in health foods. Bioland Corporation started production of HA t1y biotechnological process in 1990 for cosmetical use. At present Bioland produces HA for cosmetic and food use. We have done many researches to evaluate the helpful effect for skin and safety of HA as food. In order to evaluate the effect of HA on the skin after its oral intake, we measured its bioavailability, skin-care effects on anti-wrinkle, moisturization elasticity and desquamation by clinical trial. The results showed that HA is very safe and could bs helpful to improve anti-wrinkling, moisturization, elasticity, and desquamation on the skin.

Anti-wrinkle Effect of safflower (Carthamus tinctorius L.) seed extract (CTSE) was evaluated by determination of the anti-oxidation, collagen synthesis and elastase inhibition in normal human fibroblast. CTSE showed anti-oxidation and collagen synthesis ability as much as or greater than other phytoestrogenic compounds such as genistein or resveratrol. Consistent with collagen synthesis promotion, CTSE also showed inhibitory effect on elastase activity. In the human skin irritation test, 0.2％ CTSE did not show any adverse effect. These results demonstrate that CTSE can be useful as an anti-wrinkle cosmetic ingredient.

To investigate the effect of Panax ginseng C.A. Meyer extract (Ginseol K-b1), on skin functionality, we evaluated skin appearance and properties, such as wrinkle formation, skin moisture content, and skin elasticity in the skin of hairless mice damaged by UV irradiation. In addition, the effect of Ginseol K-b1 on collagen synthesis in human dermal fibroblasts was investigated. Female hairless mice were orally administered Ginseol K-b1 for 10 weeks with UV irradiation. Wrinkle formation in the Ginseol K-b1-treated group was significantly suppressed compared to the UV-irradiated group. Skin properties, including skin moisture content and elasticity, of the Ginseol K-b1-treated group were better than those of the control group. In the human fibroblast cells, Ginseol K-b1 treatment enhanced cell proliferation and significantly stimulated collagen synthesis. These results suggest that Ginseol K-b1 is a potent ingredient with anti-aging effects.

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.
