摘要:
The invention provides a parakeratosis inhibitor, pore-shrinking agent, or rough skin preventing/ameliorating agent that has a function such as parakeratosis inhibition, pore shrinkage, or rough skin—inhibition/abatement, poses no safety problems such as sensory irritation, and is very safe, and further provides an external composition for skin to which a compound having the above-mentioned function has been added. The parakeratosis inhibitor, pore-shrinking agent, or rough skin preventing/ameliorating agent comprises one or more compounds selected from the group consisting of β-alanine derivatives and salts thereof. The external composition for skin comprises the one or more compounds selected from the group consisting of β-alanine derivatives and salts thereof as the above-mentioned parakeratosis inhibitor, pore-shrinking agent, or rough skin preventing/ameliorating agent.
摘要:
A wrinkle-improving agent that has an effect of improving wrinkles, that does not entail problems of safety or pain even when applied to the skin, and that contains a very safe substance as an active component. A discovery was made that N-benzoyl-β-alanine, other specific β-alanine derivatives, and salts thereof have a wrinkle-improving effect, whereby a wrinkle-improving agent containing as an active component one, two, or more types of compounds selected from the group composed of these specific β-alanine derivatives and the salts thereof was developed.

The invention provides a novel wrinkle-improving agent that has an effect of improving wrinkles, that does not entail problems of safety or pain even when applied to the skin, and that contains a very safe substance as an active component. A discovery was made that N-benzoyl-β-alanine, other specific β-alanine derivatives, and salts thereof have a wrinkle-improving effect, whereby a wrinkle-improving agent containing as an active component one, two, or more types of compounds selected from the group composed of these specific β-alanine derivatives and the salts thereof was developed.
摘要:
An azabicyclo compound (I) or a salt thereof in accordance with the present invention has an excellent inhibiting action on matrix metalloproteases (MMPs) activity, and is useful for pharmaceutical, cosmetic and skin external compositions. wherein R is H, alkyl, heteroalkyl, aryl, heteroaryl, arylalkyl, heteroarylalkyl, acyl, COOR1, carbamoyl or SO2R2 (wherein R1 and R2 each are alkyl, heteroalkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl); X is methylene, ethylene or propylene; and is a single bond or a double bond.
摘要:
It is intended to provide a substance having an effect of shrinking pores by analyzing the mechanism of making pores perceptible and compositions such as a skin preparation for external use which exerts the above effect to thereby make pores imperceptible. As means for solving these problems, there are provided a parakeratosis inhibitor and a pore-shrinking agent comprising an antagonist to an excitatory cell receptor, for example, a glutamate receptor such as N-methyl-D-aspartic acid receptor or an ATP receptor such as P2X receptor, or an agonist to an inhibitory cell receptor such as a γ-aminobutyrate receptor such as bicuculline-sensitive receptor having the Cl-channel therein or glycine receptor, as well as a skin preparation for external use aiming at inhibiting parakeratosis and a skin preparation for external use aiming at shrinking pores each containing such an antagonist to an excitatory cell receptor or an agonist to an inhibitory cell receptor as described above. Owing to the effects of inhibiting parakeratosis and shrinking pores, the skin can be maintained in a healthy state without perceptible pores.

摘要:
There are provided an anti-aging composition, a collagen production promoting composition, a collagen gel contraction promoting composition, and an integrin production promoting composition for promoting integrin production in fibroblasts/epidermal cell, which have improved collagen production promotion effect and are effective for preventing or reducing wrinkle and/or sagging caused by aging. These anti-aging composition and promoting composition comprise, as an active ingredient, a hydrogen peroxide-treated yeast hydrolysate.
摘要:
A method for promoting skin basement membrane formation comprises administering matrix metalloproteinase inhibitor or matrix metalloproteinase inhibitor and matrix protein production promoting agent. The matrix metalloproteinase inhibitor is N-hydroxy-2(R)-[[(4-methoxyphenyl)sulfonyl](3-picolyl)amino]-3-methylbutanamide hydrochloride.
