The ethylhexyl methoxycinnamate is the molecular formula C ₁₈ H ₂₆ O ₃ and is also referred to as octyl methoxycinnamate. In the field of cosmetics, it was mainly used as an ultraviolet absorber to absorb ultraviolet UV-B from the sun. UV-B, which corresponds to a wavelength of 280 to 320 nm in the ultraviolet wavelength, is associated with photoaging of the skin, and photoaging is a phenomenon in which the skin is aged due to exposure to the sun. As the photoaging progresses, more and thicker fan wrinkles of the exposed face, neck, arms, and hands and pigmentation such as speckled black spots and spots are typical phenomena. Unlike biological aging, which simply becomes thinner and less structured, photoaged skin becomes uncomfortable due to the presence of abnormal, elastic fiber-like substances in the upper dermis, which can not support the skin, which is the original function of the dermis. Ultraviolet rays cause damage to skin cells directly, causing skin aging, skin cancer, and inflammation of skin, resulting in secondary damage of active oxygen species and aging caused by oxidation. As a result, it inhibits the production of collagen and elastic fibers that make up the dermis, and promotes the action of the enzymes that break down the collagen, thereby reducing both collagen and elasticity.

COSMOL 222 (S) is a diisostearyl malate with an INCI name and has a high viscosity and is excellent in pigment dispersibility, dye solubility and wax solubility.

The DUB SSOD is referred to as octyldodecyl stearoyl stearate and the molecular formula is C ₅₆ H ₁₁₀ O ₄ . The DUB SSOD improves the feeling of use of the cosmetic composition and imparts a moisturizing function.

The Dermosoft GMCY is called glyceryl monocaprylate and the molecular formula is C ₁₁ H ₂₂ O ₄ . It does not dissolve well in water but has a property of being easily hydrolyzed under strong acidic or strong basic conditions and has excellent dispersing, emulsifying and antibacterial functions and is used as a dispersant and emulsifier in personal care products.

The Sensiva SC 50 is referred to as ethylhexyl glycerin and the molecular formula is C ₁₁ H ₂₄ O ₃ . The Sensiva SC 50 has an antibacterial function and various skin regulating functions.

The aqueous solution of white ginseng polysaccharide means a water-soluble polysaccharide extracted from white ginseng, that is, dried ginseng. Generally, it can extract about 7% of white ginseng polysaccharide from white ginseng and increase skin cell ATP energy.

The above-mentioned Baekhwa reed NS has the effects of improving wrinkles and preventing sagging of skin, and is excellent in anti-inflammatory effect, antiviral, antibacterial and antifungal effect.

The essential oil base refers to a fragrance oil extracted from flowers, seeds, leaves, stems, roots, byproducts, etc. of plants, or by using a part or a plant. The essential oil base stimulates the body to stimulate metabolic functions, relaxes fatigue, relaxes the mind and body, stimulates endocrine secretion, improves mood, increases the white blood cell count, and improves immune function. It is very beneficial to the human body. And it has fat-soluble property to dissolve well in fat.

The consonants are five kinds of herbal extracts of lotus, lily, jade, peony, and rhubarb, and have the effect of controlling moisturizing action, preventing aging, improving elasticity and controlling skin balance.

The consonant herb extracts are five kinds of herbal extracts of Seiho, Yinhyeon, Nuyin, Candy, and Chaesuncho.

The fat-soluble melt is preferably 7.0 to 11.0% by weight, more preferably 8.0 to 10.0% by weight, based on the total weight of the powder cosmetic composition. The fat soluble solubility is less than 7.0% by weight based on the total weight of the powder cosmetic composition, and the ultraviolet ray shielding effect is insignificant, resulting in deterioration of the skin wrinkle improving function.
