4 Core Technologies Natural Herb Extraction (Specific Activity) - Natural UV Protector - Acne, Dandruff, Tinea Pedis - Extraction of active ingredients from plants and the increased activity by bioconversion Stable Formulation of Active Ingredients - Stabilized active ingredients through electro-spinning, micro-fluidization, 3D conformational structure and etc - Extracellular Matrix composition - Vitamin C & proteases & etc.. were stabilized through BST s safety and stability technology 4

5 Core Technologies Bioconversion - BCX-A (Anti-acnes) was developed through bio-conversion of Chamaecyparis obtusa s leaf extract. - Whitening agent (arbutin modifier) was developed through symbitic fermentation. Cell culture - ADSC (Adipose Derived Stem Cell) Filtrate, which contains many different kinds of active human growth hormone such as EGF, HGF, basic FGF, VEGF and etc. - We named ADSC (Adipose Derived Stem Cell) Filtrate as SMGF (Stabilized Mega Growth Factor) Human protein cloning EGF was cloned to vector and isolated from Sacchromyces cerevisae 5

8 Research and Development Sunscreen Ingredients ㆍ Chemical ㆍ Physical Problem ㆍ Skin trouble ㆍ Leave cast Natural Chemical Sunscreen (BHC-S) Safe for skin Provide UV protection Anti-inflammation and Anti-oxidation 8

9 Types of Sunscreen Physical ingredients - Protect the skin from the sun by deflecting or blocking the sun's rays. Advantage -Generally stable -Don't cause free radicals. -Pretty safe, FDA approved -Zinc oxide protects against the entire spectrum of UVB and UVA rays Weakness -Thick and opaque, may be hard to apply -Titanium dioxide can be problematic for some people 9

10 Types of Sunscreen Chemical ingredients - Chemically synthesized ingredients work by absorbing the sun's rays. Advantage Weakness - Must wait at least 20 minutes after -Colorless, odorless, usually runny -Good feeling when applied. -White residue does not leave on the skin. application for effective sun protection -Can cause dermatitis or allergic, phototoxic reactions and cancer - Can cause hormonal disorders 10

15 Research Strategy Development of natural sunscreen for replacing chemical and physical ingredients. 1.Screening of natural extracts which has sunscreen efficacy. 2.Bio-assay was performed with UV sensitive yeast strain. 3.Natural extracts of UV absorbance was compared with chemical & physical ingredients. 15

16 Developmental Process Step 1 : UV Spectrum assay (Screening assay from Natural Products Library) Step 2 : Bio assay (UV sensitive Saccharomyces strain) Step 3 : Development of Natural sunscreen 16

17 Efficacy of Natural Extracts - Efficacy of Arachis hypogaea fruit extract 1) Vitamin E in Arachis hypogaea fruit extract contains much anti-oxidant efficacy, which helps to prevent aging. 2) Resveratrol, a polyphenolic compound found in Arachis hypogaea fruit extract has efficacy of anti-cancer, anti-viral, anti-aging and anti-inflammation. -Efficacy of Oryza sativa bran oil extract 1) Vitamin B1, B6, Vitamin E : -can prevent freckles, atopy and wrinkles. - maintain moisture in the skin. 2) Strong anti-oxidizer : - can absorb UV and has strong anti-oxidant efficacy - is used in food, cosmetics and medicine. 17

18 Efficacy of Natural Extracts - Efficacy of Centella asiatica extract 1) can regenerate the skin by stimulating the synthesis of collagen. 2) has the efficacy of anti-acnes and anti-wrinkles 3) maintain the skin tension and help to whiten the skin. - Efficacy of Ecklonia kurome extract 1) help to cure the osteoarthritis 2) has the efficacy of anti-inflammation and anti-oxidant. 18

23 Efficacy of BHC-S 1. Parsol MCX 2. BHC-S 3. control 1. Parsol BHC-S 3. control UV sensitive yeast strain (without DNA repair system) The UV protection of BHC-S was compared with Parsol MCX and 1789 after exposure of Petri dish to UVB for 150 seconds. UV Protection rate of BHC-S and those of Parsol MCX and Parsol 1789 was almost same. 23
