This report describes the successful resolution of an epidermoid cyst using a minimally invasive approach with intralesional injection of recombinant enzymes.

This study developed a sustainable biotechnological process using Bacillus licheniformis strains to produce keratin hydrolysate from chicken feathers, and found that cosmetic hair serum with this ingredient improved hair smoothness, elasticity, and shine in a small focus group.

This study demonstrated that a daily oral supplement of 1000 mg Kera-Diet® improved hair and nail conditions in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

This study observed that a peptide showed higher antioxidant and metal ion chelation activity compared to its encapsulated version cross-linked in calcium alginate beads.

This study concludes that egg shell membrane hydrolysates, particularly Fraction I, may effectively mitigate UV-B radiation-induced wrinkles and promote skin collagen and hyaluronic acid production, suggesting potential use in functional cosmetics.

This study found that ultrasonication pre-treatment at various power levels improved the color, protein solubility, and degree of hydrolysis of fish protein hydrolysates from mackerel side streams, and potentially reduced bitterness by decreasing hydrophobic free amino acids.

This study found that protein hydrolysates from mealworms, especially those derived using flavourzyme, significantly enhance adipogenic differentiation in 3T3-L1 preadipocytes, suggesting their potential as sustainable ingredients for glycemic control, skin health, and tissue regeneration products.

In this study, hydrolysates of lactic acid bacteria were found to enhance hair growth in C57BL/6 male mice more effectively than 5% minoxidil.

This article reviews human placenta hydrolysates and their complex molecular mechanisms in treating various conditions but does not present new clinical findings.

This study found that adding microcapsulated pumpkin seed protein hydrolysate to aloe vera drinks improved antioxidant activity, taste, and shelf life, with chitosan-alginate microcapsules effectively inhibiting microbial growth during 30 days of refrigerated storage.

This study suggests that IGF-1, a component of human placenta hydrolysate, promotes hair growth by increasing the number and size of hair follicles in mice.

This study found that Katsuwonus pelamis heart hydrolysates promoted hair growth in human dermal papilla cells, a 3D hair follicle organoid model, and C57BL/6 mice, suggesting its potential as a bioactive hair growth ingredient.

This source provides a review of patents on the use of fish collagen peptides in wound care, highlighting benefits like skin hydration, scar repair, and antiaging, while emphasizing the need for further clinical research to validate these applications.

In this study, researchers found that supplementation with L-cystine, either alone or with a keratin hydrolysate, significantly improved hair density, hair and nail brightness, and nail growth in women experiencing acute telogen effluvium and brittle nail syndrome over three months.
