Description

Composition for improving pores The present invention relates to a cosmetic composition comprising escin, and by including said escin, can provide a cosmetic composition that exhibits skin pore improvement effects such as inhibiting sebum production and reducing the volume, area, density, and number of skin pores. Increased sebum secretion and the resulting enlargement of pores are known to be major causes of skin problems such as skin trouble and loss of elasticity. In particular, acne bacteria (Cutibacterium acnes, C. acnes) break down triglycerides in sebum to produce free fatty acids, thereby lowering the skin's pH and inducing an inflammatory response (Pharmaceutics. 2022 Feb 4;14(2):360). In this process, sebum oxidizes and pores enlarge, resulting in skin damage and ultimately leading to rough and sagging skin. Meanwhile, the decrease in dermal elastic fibers and collagen due to skin aging and UV exposure is also reported to be a major factor in enlarged pores and skin sagging. In particular, MAGP-1 (Microfibril-Associated Glycoprotein-1) is an extracellular matrix protein essential for the formation and stabilization of elastic fibers, playing a crucial role in maintaining the skin's mechanical elongation and resilience. According to recent studies, gene and protein expression levels of MAGP-1 are significantly reduced in aged and photoaged skin, and loss of the MAGP-1 fibrous network is observed particularly in the hair follicle and peripore areas; it has been reported that a decrease in MAGP-1 is closely associated with enlarged pores and reduced skin elasticity (Clin Cosmet Investig Dermatol., 2013, 6:317-323). In other words, it has been revealed that not only sebum oxidation and inflammation, but also the weakening of the structural support network in the dermis acts as a significant cause of enlarged pores. Recently, there has been an increasing demand among consumers to simultaneously address complex skin issues such as excessive sebum, enlarged pores, and reduced elasticity. In particular, as the trend toward hypoallergenic, naturally derived ingredient-based cosmetic compositions expands, the need for developing cosmetic compositions containing new active ingredients is growing. Figure 1 is an example confirming the pore-improving effect of the composition of the present invention. This is explained in detail as follows. Meanwhile, each description and embodiment disclosed in the present invention may be applied to each other description and embodiment. That is, all combinations of the various elements disclosed in the present invention fall within the scope of the present invention. Furthermore, the scope of the present invention should not be considered limited by the specific descriptions provided below. Furthermore, a person skilled in the art can recognize or identify a number of equivalents to a specific embodiment of the present invention using only ordinary experiments. In addition, such equivalents are intended to be included in the present invention. One embodiment of the present invention provides a cosmetic composition for improving skin pores comprising escin. In the present invention, the term "improvement of skin pores" refers to a state in which morphological or physical indicators related to skin pores are improved. Specifically, it means that the production of sebum within the pores is suppressed, or that the volume, area, density, or number of pores is reduced. The said improvement of pores refers to a state in which the size of the pores or the degree of sebum production is reduced, thereby alleviating roughness or unevenness of the skin surface and improving the cleanliness and uniformity of the skin's appearance. In the present invention, the term "inhibition of sebum production" refers to a phenomenon in which the production of sebum (e.g., fatty acids, waxes, etc.) secreted by sebaceous glands within pores is reduced. Specifically, it refers to a state in which the activity of lipase secreted by skin microorganisms (e.g., Cutibacterium acnes) is inhibited, thereby reducing the production of free fatty acids, which cause skin irritation and inflammatory reactions, by breaking down triglycerides within the sebum. In the present invention, the term "reduction in pore volume" refers to a state in which the average or total volume of pores within a certain area decreases before and after the application of the composition, and may include a reduction in the unevenness of the skin surface and may be evaluated as the rate of change in pore volume. In the present invention, the term "reduction in pore area" refers to a state in which the average or total area of pores is reduced, and can be evaluated by the rate of change in the area occupied by pores before and after the application of the composition. In the present invention, the term "reduction in pore density" means a state in which the number of pores per certain area (e.g., 1 cm² ) is reduced. In the present invention
