Antioxidants are among the most important cosmeceuticals, with proven ability of inhibiting cellular damage. The topical skin administration of antioxidants is essential for minimizing skin aging and achieving better skin protection against harmful free radicals. However, their unfavorable physiochemical properties such as chemical instability, excessive hydrophilicity or lipophilicity and others could be a great obstacle against their skin promising effects as well as their delivery to deeper skin layers. These problems could all be remedied through the use of delivery carriers...

The recent hype surrounding the antimelanogenic properties of glutathione has resulted in physicians frequently administering it as a "wonder" drug for skin lightening and treatment of hyperpigmentation, especially in ethnic populations with darker skin tones. This phenomenon has seen a recent surge owing to aggressive marketing and capitalization of pharma-cosmeceutical companies. However, the unbridled and prodigal use of it, especially as a parenteral formulation, seems unjustified, given the lacunae in our knowledge about its antimelanogenic potential, limited clinical evidence favoring its role in skin lightening, and the statutory ban/advisory issued by certain federal agencies...

Bioactive peptides contribute to various cellular processes including improved skin physiology. Hence, bioactive keratins have attracted considerable attention as active cosmetic ingredients for skin health. Here, we obtained low molecular weight (LMW) keratins from native chicken feathers by anaerobic digestion with an extremely thermophilic bacterium Fervidobacterium islandicum AW-1, followed by stepwise fractionation through ultrafiltration. To assess the effects of the feather keratins on skin health, we performed in vitro and ex vivo assays to investigate their inhibitory effects on matrix metalloproteinases (MMPs)...

Skin is the largest and easily accessible organ of the body. Increases in incidences of dermatological disorders, demand for drug targeting, and patient compliance have increased the popularity of topical drug delivery amongst the people. However, drug delivery across the skin is still a challenge for researchers because permeation of maximum drugs is hindered by the upper layer of the epidermis (stratum corneum). Several approaches like use of chemical permeation enhancers and physical methods such as sonophoresis, iontophoresis, electroporation, microneedles, etc...

As is the case for terrestrial organisms, carotenoids represent the most common group of pigments in marine environments. They are generally biosynthesized by all autotrophic marine organisms, such as bacteria and archaea, algae and fungi. Some heterotrophic organisms also contain carotenoids probably accumulated from food or partly modified through metabolic reactions. These natural pigments are divided into two chemical classes: carotenes (such as lycopene and α- and β-carotene) that are composed of hydrogen and carbon; xanthophylls (such as astaxanthin, fucoxanthin and lutein), which are constituted by hydrogen, carbon and oxygen...

Procollagen type I carboxy-terminal propeptide (PICP), derived from type I procollagen, has been identified as an indicator of type I collagen synthesis in bone matrix formation and skin recovery. PICP is a heterotrimeric glycoprotein consisting of two α1 chains (PICPα1) and one α2 chain (PICPα2). Here, we report the recombinant expression of human PICP using a mammalian expression system. Co-expression of PICPα1 and PICPα2 in HEK293F cells resulted in the production of functional PICP in the correctly assembled heterotrimeric form...

Zoe Diana Draelos
The male cosmeceutical market is still underdeveloped. Although women embrace skin care as a part of general health, this concept has not gained wide male acceptance. Shaving is probably the most beneficial daily grooming event men commonly undertake for skin appearance and may account for the failure of antiaging cosmeceuticals to attract attention in this segment. In addition, there are many physiologic differences between male and female skin, with less of a need for moisturization and photoprotection in men...

The stilbene derivative resveratrol (3,5,4'-trihydroxy-stilbene; RESV) has become the subject of interest of many researchers and the pharmaceutical industries due to its well-acclaimed beneficial biological activities. Although earlier research tended to focus on the effects of RESV on cardiovascular disorders, many other studies have described the beneficial effects of RESV in the areas of cancer chemoprevention and inflammation and interest of researchers on this compound is still increasing. It is now well accepted that the effect of RESV is not just due to its so called "antioxidant" activity but mainly (if not only) because of the ability of this compound to trigger cell signaling pathways and gene expression involved in cellular defense systems...
