Effects of Avocado Yoghurt, Three Beans Cookie, and Tiger Nut Galsu Drink on Fibroblasts (Hs68) and Keratinocytes (HaCaT)

Abstract

The present study aimed to investigate the effects of skin care foods on the synthesis of pro-collagen type I C peptide and suppression of matrix metalloproteinase (MMP)-1 secretion through an in vitro study using fibroblasts (Hs68 cells) and keratinocytes (HaCaT cells). Among the three skin care foods developed in this study, three beans cookie and avocado yoghurt influenced the production of pro-collagen type I C peptide and suppressed MMP-1 secretion; however, tiger nut Galsu drink did not exhibit these effects. All skin care foods, including three beans cookie and plain yoghurt (50 μg/mL, p<0.001) influenced the suppression of MMP-1 in addition to other commercially available breast milk production support foods examined, such as Heath Heather (50 μg/mL, p<0.001), Happy Mama (50 μ g/mL, p<0.01), BioLys (50 μg/mL, p<0.001), Enfamama (25 μg/mL, p<0.0001), and Pregnagen (25 μg/mL, p<0.001). Avocado fruit yoghurt (25 μg/mL, p<0.05), avocado fruit jam yoghurt (50 μg/mL, p<0.01), Enfamama (100 μg/mL, p<0.05), and Pregnagen (100 μg/mL, p<0.05) influenced the production of pro-collagen type I C peptide and suppressed MMP-1 secretion. This result indicates that only avocado jam yoghurt significantly influenced both the prevention of skin keratinization and acceleration of recovery of skin fibrous structure. Therefore, avocado is a favorable ingredient for nutrition-balanced dietary foods or an essential ingredient in products for revitalization of human skin.
