Journal of the Society of Cosmetic Scientists of Korea, volume 31, issue 3, 2005, Pages 213~218
Recently, with the remarkable increase in elderly persons and improvement of skin care technique, the requirements of customer for anti-aging care have become very important. Also, after cosmeceutical-product law was done in 2001, the major interesting field in cosmetic industry has been focused to developing anti-aging materials having safety and efficacy by basic science. In this review, we ill introduce the trend of anti-aging research and materials to prevent wrinkle or improve elasticity of skin.

Glycolic acid, an alpha-hydroxy acid derived from fruit and milk sugars, has been commonly used as a cosmetic ingredient since it was known to have photo-protective, anti-inflammatory effects, and anti-oxidant effect in UV-irradiated skin. However, little has been know about the functional role of glycolic acid on UV-induced skin cell proliferation. It was previously found that glycolic acid inhibited UV-induced skin tumor development in hairless mouse. As a possible mechanism of glycolic acid on the UV-induced skin tumor development, the ability of glycolic acid to inhibit the UVB-induced cell growth and possible mechanisms were investigated. Glycolic acid treatment attenuated the UV-induced cell proliferation and apoptotic cell death in the skin. In vitro study, glycolic acid inhibited the UVB-induced cell growth and apoptotic death through inhibiting caspase-3 activity. These results suggest that glycolic acid may exert the Inhibitory effect on the UVB-induced skin tumor development by regulating cell growth and apoptotic cell death.

Skin aging is not a disease nor an abnormal phenomenon but a collection of degenerative changes with age, characterized by skin dryness, wrinkle formation, and loss of skin elasticity. The skin wrinkles are caused by either genetically predisposed factors or environmental factors such as UV irradiation or physical/chemical stimulus. The histological manifestations of wrinkles are changes in both amount and integrity of elastic and collagen fibers. Here we report the isolation and characterization of 3 active compounds, prangenidin, 8-hydroxybergapten, and xanthotoxol from Angelica dahurica root. The anti-wrinkle activities of these compounds were also investigated.

Sunscreens have been in use for about 70years and 'tanning without burning' was propagated as their major advantage. The objective changed from 'getting a tanned skin' to 'getting skin protection' since UV have been proposed to a major risk of skin cancer and the risk of developing skin cancer related also to non-burning UVA. The new expectation from consumers has triggered the development of new UV absorbers and led to the approval of 7 new, organic UV absorbers in Europe over the last few years. The significant progress due to these new UV absorbers will be discussed in this report. These UV absorbers provide an efficient absorption of UV radiation (UVB and/or UVA) and easily incorporate in any kind of formulation. These are also safe, i.e. devoid of adverse effects. These new filters give the formulators new possibilities to cover the whole UV range iron 290 to 400 nm, and also to use less filter due to the boosting effect of the new UVA and broadband fitters.

Safety is one of the key issue in the regulation of cosmetics. Cosmetic Act deals with it in Korea. The guidance for the testing cosmetic ingredients and their safety evaluation are prepared by Korea Food and Drug Administration. Ultraviolet radiation could Induce skin damage, edema, erythema, photoaging, immune dysfunction and skin cancer. Ultraviolet radiation is classified as Group 2A(probably carcinogenic to humans) by International Agenry for Reaserch on Cancer(IARC). The in vitro methodologies for evaluating the toxic potential of ingredients reported in the literature have not yet been sufficiently validated for use in areas other than the study for mutagenicity/genotoxicity, for pre-screening for severe irritancy, for screening of phototoxicity and for evaluating the percutaneous absorption. The 3T3 neutral red uptake photoxicity test (3T3 NRU PT) was accepted as OECD toxicity guideline in 2002. The 3T3 NRU PT is an in vitro method based on a comparison of the cytotoxicitv of a chemical when tested in the presence and in the absence of exposure to a non-cytotoxic dose of UVA/visible light.
Development of Non-contact Image Measuring Technique for Evaluating Micro-relief

Journal of the Society of Cosmetic Scientists of Korea, volume 31, issue 3, 2005, Pages 253~257
Assurance of the objectivity and reproducibility is a major key point in wrinkle measurement used for evaluating the degree of skin aging. The measurement of relief is quickly converted to a non-contact method, of which tools or instruments do not come in contact with skin directly, to minimize the artificial effects which influence the shape or depth of the relief. Here, we showed how wrinkle measurement techniques have been changed briefly and compared PRIMOS and replica method in the point of view of measurement principle and features, the former is non-contact fringe projection tool and the latter is contact type of the method.

The aim of the present study is to evaluate relationship between UV-induced MED and perfusion value assessed by Laser Doppler Perfusion Imager. In this study, A increasing linear relationship is seen between perfusion and dose (p<0.05). The dose-response curve show a steep slope in the case of lower MED values group after MED point, For higher MED group, increase with a gentle slope.
Antioxidant and Whitening Activity of Essential Oils

This study is performed to investigate the effects of citrus essential oils on melanin production in B16 melanoma cells and reactive oxygen species (ROS) generation in RBL 2H3 cells. Five kinds of citrus essential oil (bergamot, grapefruit, lemmon, mandarin, petigrain) did not have any influence on DPPH radical scavenger activity, cell growth and cytotoxicity in B16 melanoma cells. In purified tyrosinase assay, both mandarin and petigrain essential oils dose-dependently inhibited its activity, but bergamot did not. In
B16 melanoma cells, all of 5 citrus essential oils inhibited melanin production in
dose dependent manner. On the other hand, four kinds of citrus essential oil dose-dependently increased ROS generation in RBL 2H3 mast cells, but mandarin did not. From the above results, it is possible that citrus essential oils nay be developed to be anti-melanogenic agent on the basis of their inhibitory effect on MSH-induced melanin production. Hut we can not rule out the possibility of the induction of allergy and inflammation since citrus essential oils caused ROS generation in RBL 2H3 mast cells.

This study was performed to develop new cosmeceutical agents with sebosuppressive activity from native plant extracts in Korea. Inhibitory efforts of the extracts on
(5-AR) were evaluated by enzyme kinetics analysis using UV-spectrophotometric method. Two kinds of enzyme suspensions as 5-AR sources were prepared from rat liver tissue and cultured hSG cells. The sebosuppressive effects were determined by measuring the total lipid quantity produced in cultured hSG cells after incubation with the extracts. As a result, Pinus thunbergii extracts showed the most potent 5-AR inhibitory effects. Its
values were 0.0002% and 0.0014% for rat liver 5-AR and human sebaceous gland 5-AR, respectively. Addition of Pinus thunberii extract to hSG cells showed 48% reduction in total lipid production at 0.005% concentration. In conclusion, Pinus thunbergii extracts can be used as a cosmeceutical agent to regulate sebum production and to alleviate the sebum-involved skin diseases, such as acne and seborrheic dermatitis.

The content of lipid or moisture and index of erythema or melanin on each facial part of 170 urban middle-aged women without dermic disease was measured by non-invasive method. This measurement intended to understand the skin condition on each facial part of middle-aged women, and to determine the correlation between objective measured values and subjective symptom of lipid content/moisture content. The results was summarized as follows. At each facial Part, the order of moisture content was eye rims, forehead, and cheek and that of lipid content was forehead, eye rims, and cheek. The erythema index was in the order oi forehead, cheek and eye rims and melanin index, in the order of eye rims, forehead and cheek. It turned out that the middle-aged women generally lacked lipid content rather than moisture one. The objective measured values of lipid content coincided with subjective symptom of lipid type. The lipid content, erythema index and melanin index showed correlation significantly.
