In 2022, the domestic production performance of functional cosmetics in South Korea reached 4.6 trillion won, accounting for 33.85% of the total cosmetics production. The number of functional cosmetics reviewed increased by about 7.5% from the previous year, totaling 974 items. Especially with the increasing importance of the skin barrier function due to skin sensitivity caused by various environmental pollutants, domestic cosmetic companies are showing interest in the development of new ingredients and products related to this area. This study aims to analyze academic research trends related to in vitro experiments for the development of cosmetics improving the skin barrier, to provide practical information for the cosmetic industry. The findings are as follows: Academic research mainly focused on the efficacy of natural ingredients in improving the skin barrier, but there is a significant lack of quantitative accumulation of research. For the development of skin barrier-improving cosmetic ingredients, efficacy evaluation indicators were set, including hyaluronic acid production, expression of filaggrin gene, loricrin, formation of cornified envelope (CE), and expression of ceramide synthesis enzyme genes. Moreover, effective cosmetic ingredients for improving the skin barrier included lemongrass and perilla leaf extracts, flavonoids, Lactococcus lactis subsp. lactis, Exosomelike Nanovesicles derived from apple callus, Eleutherococcus sessiliflorus, Acanthopanax sessiliflorus, Eleutherococcus gracilistylus, Acer okamotoanum extracts, Aloe vera adventitious root extract, ethanol extract of Aruncus dioicus, and organic solvent fraction of Dracocephalum argunense.

Scars can cause great psychological stress among patients. Currently, there are numerous topical agents, laser and surgical treatments available for skin rejuvenation and scar minimization. Laser-assisted drug delivery (LADD) is a treatment method that increases drug delivery by stimulating the skin physically and chemically to enhance the penetration of topical agents. This is one of the areas of great interest in the treatment of various skin diseases in addition to its use for cosmetic purposes. In particular, LADD is relatively non-invasive and has advantages in terms of accessibility and stability. Poly-L-lactic acid (PLLA) is a collagen stimulator known to gradually restore skin volume by inducing inflammation and fibroplasia. Herein, we report a case of treatment of an atrophic scar with fractional carbon dioxide laser-assisted PLLA delivery.

This study aims on observing the recognition and attitude of caring for outer appearance by deducing the factors of men caring for their outer appearance at current point where male position is being emphasized in the appearance related market and their interest for outer appearance care is increasing. As a result of conducting a survey, male appearance caring behavior was distinguished into fashion, skin and cosmetic, cosmetic surgery, physical image, and hair factors, and among them, physical image factor showed the highest average, which proves that men generally have positive attitude towards caring for their looks. Concerning skin and cosmetics, the results show that interest is high regardless of age and occupation, and the lower the age is, the higher average for fashion, cosmetic surgery, and hair factors, proving that young men have more interest for caring after their looks. However, there was difference in outer appearance caring behavior pursued or favored by each age bracket according to the higher average for physical image in the age bracket higher than 30. Also, each factor of outer appearance caring behavior turned out to have significant correlation to each other.

Biologically active peptides, including growth factors and cytokines, participate in various biological processes in human skin. They could provide a great advantage of maintaining healthy skin. Many peptide growth factors like epidermal growth factor (EGF) and human growth hormone (hGH) have been used in cosmetic formulations. The delivery of peptide growth factors across the Stratum corneum, however, seems not sufficient because of their physical properties such as high molecular weight and hydrophilicity. So increasing the penetration of growth factors of interest into skin would be a major concern for ensuring their maximum biological efficacy. In this study, we have identified several skin penetration-enhancing peptides which facilitate delivery of growth factors, when fused at N-terminus of the target protein, into skin. For efficient and rapid screening, we constructed a skin-penetrating assay system using Franz cell and porcine skin. Next, we carried out phage display screening using M-13 bacteriophage with random 12 -amino acid library on its coat protein P3 on that system. After several selection rounds, peptide sequences facilitate the penetration of phages through the porcine skin were identified from a large population of phages. We found that phages with the most potent peptide (S3-2, NGSLNTHLAPIL) could penetrate the porcine skin eight times more than those with control peptide (12 mino acids scrambled peptide). Furthermore, growth factors conjugated with S3-2 peptide penetrate porcine skin three to five times efficiently than non-conjugated growth factors. In conclusion, our data shows that the skin penetration-enhancing peptide we have characterized could increase the delivery of growth factors and is useful for cosmeceutical application.
