As there is a growing interest in natural ingredients, they are actively being studied to improve damaged skin However, the lip cosmetics are still being inadequately studied on the exposure of lips to several stimuli and easy flow of chemical on the lips into the body. This study was conducted to make a clinical evaluation on the real effect of lip balm on lips, by extracting oil from Chamaecyparis obtusa and Lithospermum erythrorhizon that are known to play a positive role on skin. The following three natural lip balms were produced: lip balm made with Chamaecyparis obtusa(LBWCO), lip balm made with both Chamaecyparis obtusa and Lithospermum erythrorhizon(LBWCOLE), lip balm made without Chamaecyparis obtusa or Lithospermum erythrorhizon(LBWICOLE). The quality of LBWCO or LBWCOLE was evaluated to be higher than that of LBWICOLE. LBWCO and LBWCOLE had the highest satisfaction and purchase intention, respectively. As stated above, Chamaecyparis obtusa and Lithospermum erythrorhizon could be the ingredients of lip balm, and they were effective in improving damaged lips. Consequently, this study will provide opportunities to explore excellent ingredients to be used in natural lip balm. Also, studying lip cosmetics using only the natural ingredients will provide opportunities to expand positive images of ingredients for producing lip cosmetics.

Lips have a unique desquamation process and moisturizing properties that are structurally different from ordinary skin. In particular, the turnover cycle of the stratum corneum is fast and the outermost stratum corneum is thin, so the amount of keratin is relatively high, and there are no skin appendages, so it is very vulnerable to maintaining moisture. In this study, we set three targets for lip care : stratum corneum, moisture, and barrier, and aimed to identify the potential of three target-specific ingredients for lips improvement. We confirmed the exfoliating, moisturizing, and barrier improvement efficacy of three target-specific ingredients which also have mild exfoliating effect. Specifically, we verified that Bacillus clausii extract improved skin exfoliation, gluconolactone improved skin moisture retention, and serine reinforced skin barrier function. To test the in vivo efficacy of the complex composed of three target-specific ingredients on the human lips, the lip balm manufactured with non-irritating range of concentration was applied, and we confirmed that it was effective in improving lip exfoliation·moisturizing·elasticity·wrinkles. Consequently, it was confirmed that the beauty and health indicators of the lips could be improved through the exfoliation-moisturization-barrier care of the lips and these ingredients were applied to LG H&H LIPCERIN products.

From March to August 2021, a total of 66 lip makeup products were collected from Seoul to measure the contents of lead, arsenic, cadmium, antimony, and nickel, and compared by product type (lip gloss, lip balm and lip tint), production area (domestic and imported), and user (for adults and children). The average metal contents were as follows; 0.284 ㎍/g for lead, 0.020 ㎍/g for arsenic, 0.003 ㎍/g for cadmium, 0.004 ㎍/g for antimony and 0.415 ㎍/g for nickel. The results of lip cosmetics were below the recommended maximums in regulations on safety standards for cosmetics of Ministry of Food and Drug Safety.

In this study, the method of evaluation of moisturizing ability of cosmetics using specimens was studied as an alternative method of clinical tests. Cosmetic spreadability, surface drying, and moisture loss rate of four specimens (Japanese cake (Maru mochi), Garaetteok, wheat flour, and agar) were evaluated. Also, the water loss rate of the specimens and the transepidermal waterloss were analyzed for 10 kinds of lip make-up products (5 kinds of lipstick, 3 kinds of lip balm, 2 kinds of lip gloss). The moisture loss rate (moisture evaporation sensitivity) of the agar specimen was highest in the order of agar> Garaetteok> Japanese cake> wheat flour. Agar specimens are the most suitable in terms of spreadability, surface crack, and raw material supply. Containers for the preparation of agar specimens are suitable for plastic materials with low heat transfer, which can produce convex, smooth surface specimens. In the evaluation of moisturizing ability of lip makeup products, there was a strong correlation between the water loss rate and the transepidermal waterloss rate measured with agar specimens. These results show that the proposed method can be used as one of the useful alternative test methods.

Lips have a defect in maintenance of moisture due to their thin layer. As aging progresses, lips lose volume and redness, and become wrinkled. Fat grafting and filler surgery have been used to achieve attractive lips, but little research has been reported to develop better materials to replace the present methods. Recently, a study suggests that the increase of adipocyte number can be enhancing the expansion endogenous fat. In previous study, we identified that the efficacy of Magnolia officinalis bark extract (MOBE) was effective on the induction of adipogenic differentiation. In this study, we confirmed that MOBE enhanced the differentiation of human adipose-derived stem cells on the fat mimic 3D structure built by 3D bioprinting method From further experiments in human, we established a method to quantify the severity of lip wrinkle by measurement of standard deviation of gray value using Image J software. Finally, we found that topical treatment with 1% MOBE formulated lip balm significantly improved the lip wrinkle after using for 12 weeks. In conclusion, these findings suggest that MOBE has great potential, as a cosmetic ingredient, to reduce the lip wrinkle through the effect of promoting adipogenic differentiation.

This study aimed to provide the fundamental data on the field of cosmetics by comparing heavy metal concentration in terms of domestic/foreign products, types and colors. The study determined the concentrations of lead, cadmium, arsenic, chromium, antimony, nickel, copper and cobalt in cosmetics such as lipstick, lip gloss, lip balm, foundation and eye liner. From the period of January to August, 2013, 121 samples were collected from cosmetic stores distributing to the general market. The average metal concentrations were as follows; $0.663{\mu}g/g$ for lead, $0.010{\mu}g/g$ for cadmium, $0.056{\mu}g/g$ for arsenic, $1.144{\mu}g/g$ for chromium, $0.008{\mu}g/g$ for antimony, $0.405{\mu}g/g$ for nickel, $0.319{\mu}g/g$ for copper and $0.108{\mu}g/g$ for cobalt. Except for chromium, the heavy metal concentrations were significantly higher in foreign products than in domestic products (p < 0.05). Also, The mean concentrations of heavy metal were significantly different (p < 0.05) when classified by cosmetic type. The highest mean concentrations shown in lipstick were $1.430{\mu}g/g$ of chromium, $0.616{\mu}g/g$ of lead and $0.385{\mu}g/g$ of nickel, in foundation $1.155{\mu}g/g$ of lead and $1.023{\mu}g/g$ of chromium. In eye liner, the highest mean concentrations were $1.424{\mu}g/g$ of chromium and $0.830{\mu}g/g$ of nickel. Additionally, The concentrations of heavy metal were significantly different by color (p < 0.05). Brown colored cosmetics were found to have the highest mean concentrations of chromium, nickel and copper, ivory colored cosmetics the highest mean concentrations of chromium and lead, and pink colored cosmetics the highest concentrations of lead and chromium.
