Research Summary: Niacinamide, an amide of vitamin B3 (niacin), is a hydrophilic endogenous substance. Its effects after epicutaneous application have long been described in the literature. Given sufficient bioavailability, niacinamide exhibits antipruritic, antimicrobial, vasoactive, photo-protective, sebostatic, and lightening effects depending on its concentration.Within a complex metabolic system, niacinamide controls the NFκB-mediated transcription of signaling molecules by inhibiting the nuclear poly (ADP-ribose) polymerase-1 (PARP-1). Niacinamide is a well-tolerated and safe substance often used in cosmetics. Clinical data for its therapeutic use in various dermatoses can increasingly be found in the literature. Although the existing data are not sufficient for a scientifically...

Research Summary: World consumers are looking for personal care products that supply multiple benefits with minimal effort. They also expect the latest technological advances to be incorporated into innovative formulations. The trend toward therapeutic cosmetics will lead to a better understanding of modern ingredients and their assessment techniques. To obtain skin care formulations with real consumer-perceivable benefits and to optimize sensory attributes, formulators are resorting to technology that until recently was exclusively used in cosmetic products. Various formulations come under special delivery systems like Vesicular, Particulate systems, and emulsions type, along with their applications, as shown in this article. This...

Research Summary: The main function of the epidermis is to generate an impermeable outer layer, the stratum corneum. The stratum corneum can be considered morphologically and functionally as a two-compartment system composed of: 1) anucleate corneocytes (the bricks), largely made up of fibrous protein networks, and 2) the intercellular matrix (the mortar), predominantly composed of neutral lipids. Whereas much of the prior and current research on the stratum corneum has focused on the protein biochemistry leading to the formation of the keratinized corneocyte (“keratinization”), this paper is concerned with the formation, composition, and function of the intercellular matrix of the...

Research Summary: In recent decades, there has been a rising demand for anti-aging interventions aimed at postponing or potentially reversing indicators of skin aging. The use of collagen-based nutraceutical supplements has gained popularity as they have shown promise in enhancing skin health and reducing signs of aging. The aim of this randomized, placebo-controlled, blinded study was to investigate the effects of 2.5 g COLLinstant® LMW, a novel cosmeceutical containing low molecular weight (≤ 1000 Da) collagen peptides, on skin aging and health. The trial was conducted in 80 healthy women aged 30 years and older. They received a daily oral...
