Ingesting hydrolyzed collagen could be a useful strategy to counteract the changes associated with skin aging. Several proteases (eg, pancreatic proteases, small intestinal brush-border proteases, peptidase) are involved in the degradation process.

The first step in digestion consists of degradation of hydrolyzed collagen to form dipeptides and tripeptides or free amino acids. Therefore, it is imperative to demonstrate whether collagen peptides can be absorbed, and in what form and quantity, before speculating on their mechanism of action.Īccording to Richelle et al 14 bioavailability is the amount of a nutritional bioactive compound that crosses the intestinal barrier to reach the bloodstream and is made available for either storage in the body (in this context, in the skin) or a metabolic process. It is worth noting that the rate of transport across the intestinal barrier could be a controlling step that affects the efficacy of these compounds in the skin. In order to be active in the deeper layers of the skin, hydrolyzed collagen has to cross the intestinal barrier and reach the bloodstream. An important indicator of the harmful effects of chronic stress is dysregulation of the circadian cortisol/corticosterone rhythm 11, 12 which is known to alter both the synthesis and degradation of collagen. 9, 10 Stress also seems to affect the integrity of collagen in the skin. 7, 8 Recently, it has been shown that smoking alters the components of the dermis and leads to premature aging of components in the dermis. The photoaged dermis contains collagen fibers and elastin that are disorganized and abnormal in nature. 6 This results in visible signs of aging, which are usually most prominent on the face.

Moreover, aged fibroblasts synthesize less collagen, both in vitro and in vivo, when compared with young adult fibroblasts. All these factors affect fibroblasts in the dermis by causing changes in their shape and in the amount and quality of elastin and type I collagen fiber production. Advanced glycation end products remain in the tissue where they form because they cannot be degraded normally by enzymes. High sugar levels lead to development of advanced glycation end products due to a chemical reaction between glucose and the free amino groups in proteins. Both these types of aging can be exacerbated by diet. In addition, areas of the body exposed to the sun are prone to photoaging. However, natural aging can affect the structural integrity of the dermis.

5 For the skin to function normally and appear youthful, the structure of the dermal layer must be maintained because the dermis provides structural support to the epidermis, which carries the blood vessels and supplies the skin with important nutrients for its functioning. The extracellular matrix accounts for almost 80% of the skin’s dry weight. Hyaluronic acid consists of a helical chain that comprises alternating units of N-acetylglucosamine and glucuronic acid, and its average molecular weight has been shown to be in the range of 10–10 4 kDa. The molecular size of hyaluronic acid is quite important, as it affects the physicochemical properties of the skin, such as its ability to retain water, and its elasticity and viscosity. 1 Embedded within the collagen fiber network are glycosaminoglycans, comprising mainly hyaluronic acid and dermatan sulfate. The dermis, on the other hand, contains fibroblasts, which produce elastin and collagen, including type I and type III, among other extracellular matrix proteins. The former consists of cells, which are proliferating (basal), differentiated (keratinocytes), or squamous. The two main layers that make up the skin are the epidermis and the dermis. As well as having a sensory role, it provides a physical barrier against environmental factors. Skin is the largest organ in the human body, and serves several important functions.
