In the present work, Boryeong mud pack was applied to the skin of the elderly and changes in pores, wrinkles, oil, pigmentation, moisture, and elasticity were studied using a non-invasive skin diagnosis system. After applying the mud pack to the experimental group, increase in pore size, oil content, and moisture content was expected to activate the skin and promote blood circulation. In addition, it was confirmed that the depth of wrinkles and pigmentation also changed and skin elasticity increased. Therefore, from this study, it can be concluded that skin care using mud ingredients can effectively remove keratinized cells from elderly skin, and help maintain healthy skin by increasing skin elasticity and moisturizing rate.

We investigated the ultrastructure of clay minerals of Boryeong mud powder. Observation of the mud powder sample using a low-magnification scanning electron microscope showed that the powder particles were uniformly dispersed in a relatively homogeneous state, and the relatively large particles were observed in the form of crystals. Using the scanning electron microscope at high magnification of the mud powder, most of the clay mineral particles were in the form of thin plates or lobes, and some trace particles in the shape of nanometer-sized columns were observed. The crystalline mineral particles, which are relatively larger than other mineral particles, measured from 38㎛ to approximately 45㎛ in length, and had a very smooth and flat surface. These crystalline clay minerals appeared in the form of rectangles, ovals, and diamonds. In addition to the particles observed as such large crystals, most of the mineral particles measured had a major axis diameter under 15㎛.

Objectives: Boryeong Mud includes as much mineral as in the Dead Sea. Assumption that Boryeong Mud also can improve atopy immune and skin moisturizing process has been theorized. By variously moisturizing on the dry skin layer caused by atopy, I have studied the impact on the skin state improvement. Methods: Subjects are patients who have suffered from atopy. By variously moisturizing on the dry skin layer caused by atopy, I have studied the impact on the skin state improvement. 36 subjects were applied to the mud pack twice a week for 6 weeks. Results:The average moisture figure applied to Boryeong Mud has increased from 28,75(±3,412) to 49(±7,502) after the experiment.On the other hand, the average moisture figure applied to the Dead Sea Mud has increased from 30,75(±8,447) to 48,38(±6,545). Itching has been relieved after the experiment, too. average figure was 7,78(±2.635), and the opposite group(The Dead Sea) was also 7,78(±2.635) before the experiment. However both the figure has decreased to 1,11(±2.205) and,1.67(±2.500) and the itching of all the subjects has improved enormously. Conclusion: I have made sure that Boryeong Mud can be recognized as much as the Dead Sea Salt in that it can contain enough ingredients and can be produced specially according to various skin type. It can also be applied as a basic datum in esthetic field program.

The present study compared and analyzed the inorganic elements present in brownish low-priced and expensive ink products that are often used in semi-permanent makeup. Semi-permanent makeup refers to injecting a long-lasting pigment below the skin's epidermal layer such as eyebrows, eyelashes, and lips for cosmetic purposes. Iron (Fe) and titanium (Ti) elements were detected in expensive semi-permanent cosmetic ink products. Iron oxide added to the expensive ink was observed to be homogeneously distributed having the shape of rod and cube. In the low-cost ink products, the inorganic substances found were iron (Fe), manganese (Mn), silicon (Si), sulfur (S), chlorine (Cl) and sodium (Na) elements. Rod- and cubic-shaped iron oxides were easily identified in the inexpensive ink pigment. In the low-cost inks, in addition to these pigments, lump-shaped substances were also detected.
