1. Product Function
Collagen peptides function as a key bioactive ingredient in cosmetics and skincare products, leveraging their affinity for skin tissues to support structural integrity and hydration. They penetrate the skin’s outer layers to replenish amino acids (e.g., glycine, proline), which are essential for collagen synthesis—helping maintain skin elasticity, reduce the appearance of fine lines, and enhance overall texture. As a versatile additive, they also act as a humectant, binding moisture to the skin and improving product spreadability.
2. Main Advantages
Skin Compatibility: Biodegradable and non-irritating, they suit various skin types (including sensitive skin), minimizing the risk of adverse reactions.
Enhanced Absorption: Small molecular weight allows deeper penetration into the epidermis, delivering active benefits beyond surface hydration.
Moisture Retention: Attracts and locks in moisture, improving skin barrier function and reducing dryness for a plumper, smoother appearance.
Synergistic Effects: Works well with other skincare ingredients (e.g., hyaluronic acid, vitamins) to amplify anti-aging, firming, and repairing effects.
Sensory Improvement: Adds a silky, non-sticky texture to formulations, enhancing user experience in creams, serums, and masks.
