In 2021, Jung et al., in Korea, investigated whether the oral intake of enzymatically decomposed collagen peptides (acid-processed collagen peptides [APCPs]: 1000 mg suspended in 25-mL samples administered once per day) could improve skin moisture and barrier function by assessing changes in the ceramide and natural moisturizing factor (NMF) contents in the stratum corneum (SC), comparing baseline parameters to end-of-treatment parameter values [37]
Second, there are biological risks from the peptides themselves
Metalloproteinase Balance Wound healing depends on a careful balance between matrix metalloproteinases (MMPs), which break down damaged tissue, and their inhibitors (TIMPs)
