A new view concerning the effects of collagen hydrolysate intake on skin properties


Dietary supplements (vitamins, polyphenols, micronutrients and proteins) have demonstrated beneficial effects on skin health. The classical route of administration of active compounds is by topical application and manufactures have substantial experience of formulating ingredients in this field. However, the use of functional foods or nutraceuticals for improving skin condition is increasing. The preclinical efficacy assays and bioavailability trials provide a basis from which to establish appropriate collagen hydrolysate (CH) intakes that might impact skin health outcomes. This commentary deals essentially with the general aspects of CH, bioavailability and findings of preclinical studies concerning the effects of CH intake on skin. To comprehensively study the different benefits of CH on skin, controlled clinical trials are needed in addition to the previous pre-clinical and bioavailability assays. Gaps in knowledge are identified and suggestions are made for future research.
