The present invention relates to an antioxidant composition for the skin. More specifically, it relates to an antioxidant composition for the skin having:ferment; and &#x3b1;-ketoglutaric acid or niacinamide alone or a mixture thereof. The antioxidant composition for the skin according to the present invention has not only an excellent antioxidant effect but also a high long lasting effect. Therefore, it provides an enhanced antioxidant effect when applied to the skin and it enables manufacture of various products such as cosmetics and medicines because it is not harmful to the human body.

Antioxidant composition for skin

The present invention relates to a cosmetic composition using a mannosylerythritol lipid, which is a kind of glycolipid, as a stabilizer in order to prevent kojyl methylenedioxycinnamate, which is an active ingredient having various skin effects such as antiaging, whitening and antioxidation, from causing crystallization inside a dosage form. Even if the cosmetic composition according to the present invention contains a high concentration of an active ingredient, crystal precipitation does not occur in various dosage forms, and thus the functionality of the active ingredient is maximized, skin delivery is increased and the texture during use is improved.

Cosmetic composition having high dosage form stability

The present invention relates to a cosmetic composition for skin whitening and anti-aging, which contains 2 or more of collagen peptides, snake needle grass extract, and white ginseng saccharides as effective ingredients, improves skin resilience by increasing the content of collagen in the skin and suppresses the growth of melanin cells, improves skin brightness and uniformity, and alleviates skin yellowness and redness, so as to provide the effect of making the skin appear clearer and more radiant.

Cosmetic composition for whitening and improving the resilience of skin

The present invention relates to a method for calculating a thermal protection factor, wherein the method comprises the steps of: applying heat to a first area coated with a thermal protection material, and a second area not coated with the thermal protection material; measuring the respective saturation temperatures of the first area and second area; calculating a first energy by dividing the energy corresponding to the heat applied to the first area by the saturation temperature of the first area; calculating a second energy by dividing the energy corresponding to the heat applied to the second area by the saturation temperature of the second area; and calculating the thermal protection factor of a thermal protection material by dividing the first energy by the second energy or dividing the difference between the first energy and the second energy by the first energy.
