Beneficial effects of food supplements based on hydrolyzed collagen for skin care (Review)

Abstract

Ageing is a complex, multi-step process which involves, among others loss of collagen and elastin. Collagen is found in large amounts in the body, especially in the dermis layer. These fibers provide the skin's normal strength, hydration and mechanical properties. Collagen is largely available, as it can be extracted from many animal sources, it can be easily absorbed upon topical administration, hence it is largely used in the cosmetic and pharmaceutical industry for the treatment of premature aging. Bioactive peptides, such as collagen hydrolyzate, are among the most used ingredients for the development of nutraceuticals-food or food ingredients that have defined physiological effects. Numerous studies have demonstrated that peptides resulted from ingestion of hydrolysate collagen and detected in the blood stream have chemotactic properties for skin fibroblasts, helping the skin restoration process. The purpose of this minireview is to present an update on the use of hydrolyzed collagen for skin care. Contents 1. Introduction 2. Skin ageing-natural occurrence and external triggers33. 3.

Collagen Based Materials in Cosmetic Applications: A Review

“…The review of sources and application of hydrolyzed collagen has been performed by León-López et al [ 75 ]. The review on beneficial effects of food supplements based on hydrolyzed collagen for skin care has been conducted by Lupu et al [ 76 ]. This review shows that bioactive peptides, such as collagen hydrolyzate, are among the most used ingredients for the development of nutraceuticals—food or food ingredients that have defined physiological effects.…”

Depressão Pós-Parto: Uma Realidade Que Merece Atenção

“…O mosquito considerado o vetor da doença é capaz de sobreviver por apenas [35][36][37][38][39][40][41][42][43][44][45] dias, sendo seu ciclo (alimentação, reprodução e depósito de ovos) considerado diurno, com atividades preferencialmente matutinas. As fêmeas, por necessitarem de sangue humano para serem capazes de maturar e depositar seus ovos, acabam utilizando desse fenômeno para infectar seres humanos.…”

“…Dermal fibroblasts produce elastin and collagen types I and III, along with other extracellular matrix proteins. [42] Gelatin formation results from the irreversible denaturation of the collagen molecules. To stop this denaturation process, a chemical or thermal treatment can be applied.…”

“…In the cosmetic industry, marine collagen is successfully used for the treatment of wounds, burns and ulcers but also for antimicrobial protection, preventing the loss of moisture and heat from the injured tissue. [5,42] Moreover, physicochemical and functional properties of fish gelatin have been extensively studied, especially in relation to its rheological, emulsifying, foaming, film-forming and sensory characteristics.…”
