Objective : Skin aging is commonly observed in patients with diabetes mellitus, which can be accessed by the amount of skin collagen and matrix metalloproteinase-1 (MMP-1). In the present study, anti-skin-aging effects of Root Cortex of Paeonia Suffruticosa Andrews (PSA), which has been widely used to treat diabetes mellitus, are investigated. Methods : Streptozotocin (STZ) was intraperitoneally injected to rats to induce diabetes. Body weights, feed intake, organ weights, blood glucose, and other biochemical index are determined in both normal and diabetic rats. In order to study the effect of PSA on skin aging, the amount of skin collagen was measured in diabetic rats after PSA treatments. Also, MMP-1 synthesis in UVB-irradiated human skin fibroblasts was investigated. Results : 1. When PSA was administered to STZ-induced diabetic rats, feed intake was significantly increased and blood glucose and total cholesterol were decreased in a dose-dependent manner. However, there are no differences in individual organ weights, GOT, and GPT. 2. A decrease of skin collagen in diabetic rats was significantly suppressed when PSA was treated. 3. PSA also inhibited MMP-1 synthesis in UVB-irradiated normal human skin fibroblasts, similar to retinoid, a well-known effective anti-skin-aging substance. Conclusion: PSA suppressed a collagen decrease in diabetic rats and inhibited MMP-1 synthesis in UVB-irradiated human skin fibroblasts. Therefore, the treatment of PSA is very effective to slow down the skin aging process.

In this study, we have investigated the potent anti-aging effect of DA-3711, a cosmetic ingredient derived from artificial skin culture. The artificial skin was originally developed as a skin replacement for the treatment of chronic skin wounds. To produce DA-3711, neonatal human fibroblasts were seeded into biocompatible collagen/chitosan/glycosaminoglycan (GAG) scaffolds and cultured in Dulbecco's modified Eagle's medium (DMEM) supplemented with fetal bovine serum and nonessential amino acids. Analysis of the culture broth (DA-3711) showed that growth factors such as VEGF, TGF-$\beta$, KGF were present at significantly higher levels that in the culture broth of fibroblasts cultured in monolayer. The biological activity of DA-3711 was assessed by measuring in vitro cell proliferation and collagen synthesis of normal human fibroblasts. Fibroblasts treated with 10％ DA-3711 showed a 2-fold higher proliferation and 2 to 4-fold higher collagen synthesis than untreated cells. DA-3711 also exhibited anti-oxidative effects, since cells under peroxide-induced oxidative stress showed a 30％ higher viability in DA-3711-containing medium than in medium without DA-3711 addition. The results suggest that DA-3711 may have anti-aging effects by stimulating skin regeneration and protecting against oxidative stress.

Aging of the face is mainly related to the features that are sagging or loss of elasticity of the skin by reducing the volume around the eyes or cheek. Intrinsic aging can be seen to cause thinner dermis, reduction of extracellular matrix and subcutaneous fat. This study was carried out to investigate the skin volume augmentation and anti-wrinkle effects of Tribulus terrestris fruit extract. Skin anti-aging effect of Tribulus terrestris fruit extract was evaluated by using lipid accumulation, expressin of type I procollagen and elastin in preadipocytes and human dermal fibroblasts. Tribulus terrestris fruit extract augmented preadipocytes differentiation about 56% at 100 µg/mL. The type I procollagen and elastin were increased about 35% and 25% by treatment 20% Tribulus terrestris fruit extract, respectively. The clinical study also showed that skin sagging, skin elasticity, and dermal density improved without adverse effect following 4 week application of cream containing 2% Tribulus terrestris fruit extract. We suggest that Tribulus terrestris fruit extract can have the good possibility as skin volume augmenting, skin elasticity and wrinkle improving agent.

Ginsenosides are bioactive components of Panax ginseng with many functions such as anti-aging, anti-oxidation, anti-inflammatory, anti-fatigue, and anti-tumor. Ginsenosides are categorized into dammarane, oleanene, and ocotillol type tricyclic triterpenoids based on the aglycon structure. Based on the sugar moiety linked to C-3, C-20, and C-6, C-20, dammarane type was divided into protopanaxadiol (PPD) and protopanaxatriol (PPT). The effects of ginsenosides on skin disorders are noteworthy. They play antiaging roles by enhancing immune function, resisting melanin formation, inhibiting oxidation, and elevating the concentration of collagen and hyaluronic acid. Thus, ginsenosides have previously been widely used to resist skin diseases and aging. This review details the role of ginsenosides in the anti-skin aging process from mechanisms and experimental research.
