摘要:
Short tri- and tetrapeptides according to the following Formula I Ar(CH2)mX1—X2—CO—X3—X4—X5-(Trp)n-NX6R are potent, selective agonists of melanocortin 1 receptor (MC1R). Provided herein are skin care compositions including Formula I peptide agonists of MC1R and methods of regulating a skin condition of a mammal that include applying to a treatment surface of the body a safe and effective amount of a skin care composition including a Formula I peptide. The peptides, skin care compositions, and skin care methods described herein are useful in regulating a skin condition of a mammal associated with exposure ultraviolet (UV) radiation, including sunburn, UV sensitivity, photoaging, and skin pigmentation, particularly in the absence of sun exposure.

The invention relates to 2,4,6-octatrienoic acid derivative compounds having general formula (I) (CH3—CH═CH—CH═CH—CH═CH—CO—O—)n—R (I) consisting of esters wherein n=1, 2, 3 and wherein R is selected from alkyl, aryl or cycloalkyl of a polyol, phenol or phenolic acid; or consisting of a salt wherein n=1 and R=arginine, as active ingredients in a pharmaceutical or cosmetic composition having a combined antioxidant activity against free radicals together with an anti-inflammatory action.
摘要:
Compositions containing a combination of nicotinamide riboside and pterostilbene for treating skin disorders, and methods of treating skin disorders using these compositions and their equivalents are described. The skin disorders that are treated using these compositions or methods include sun exposure-related skin disorders, inflammatory skin disorders, autoimmune disease-related skin disorders and cancer-related skin disorders. In one embodiment, the compositions containing a combination of nicotinamide riboside and pterostilbene are prepared as oral formulations.
摘要:
The present invention provides a bacillus sp. having a deposit access number of CGMCC NO. 5744 and a hyaluronidase produced by the bacillus and the amino acid sequence of the hyaluronidase is shown in SEQ ID NO: 2. The present invention further relates to a process for preparing oligomeric hyaluronic acid or salts thereof or low-molecular-weight hyaluronic acid or salts thereof by using the bacillus or the hyaluronidase produced thereby. The produced oligomeric hyaluronates or low-molecular-weight hyaluronates have advantages such as good transdermal absorption ability, high purity, no cytotoxicity, potent antioxidant ability. The present invention also provides use of the bacillus having a deposit access number of CGMCC NO. 5744, or the hyaluronidase, oligomeric hyaluronates or salts thereof, low-molecular-weight hyaluronates or salts thereof produced by the bacillus in the fields of osmetics, food products and medicines.
