Abstract: The present invention relates to a fusion peptide, in which a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human Type-I collagen C-terminal derived peptide, a preparation thereof, and a skin anti-aging cosmetic composition comprising the same. Since the fusion peptide, in which the Tat peptide is bound to the human Type-collagen C-terminal derived peptide is highly stable and has a superior skin absorption capability, the present invention provides a skin anti-aging agent having superior synthesis of collagen and hyaluronic acid, anti-aging effects, and improved durability of the effects.

Abstract: The present invention relates to a fusion peptide wherein a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human parathyroid hormone-derived peptide, a preparation thereof, and a skin slimming cosmetic composition comprising the same. Since the fusion peptide wherein the Tat peptide is bound to the human parathyroid hormone-derived peptide has high stability and superior skin absorption, the present invention provides a skin slimming agent having superior lipolysis effects and improved durability of the effects.

Abstract: The present invention relates to a novel zinc magnesium titanate represented by formula (I): Zn2−xMgx.yTiO4 in which x denotes a real number of 0.5 to 1.5; and y denotes an integer of 1 or 2, and to a process for preparing the same and a thermoregulating functional composition which comprises zinc magnesium titanate of formula (I).

Abstract: A cosmetic composition for preventing and treating acne, contains cryptotanshinone as an effective component. The cosmetic composition containing cryptotanshinone can be safely used without any side effect on skin, and further, can very effectively control the amount of sebum secretion due to inhibition of 5 &agr;-reductase activation, and has superior anti-bacterial and anti-inflammation ability.
