9. Natural Protein Source

Collagen stands out as a naturally occurring protein, making it especially attractive to those who prioritize clean, natural beauty solutions. Unlike synthetic peptides or artificial fillers, collagen is derived from animal or marine sources and closely mimics the body’s own structure.
Natural beauty enthusiasts often prefer collagen over lab-created alternatives for its compatibility and minimal processing. According to Healthline, this alignment with the body’s biology supports its effectiveness and safety, further fueling its popularity among those seeking wholesome, science-backed beauty products.
