Micro-plastic surgery and injection cosmetology are hot topics at present. Many women who love beauty will choose to go to the hospital for injection plastic surgery to improve their skin condition. Collagen and hyaluronic acid are two common injection materials, so what is the difference between collagen and hyaluronic acid? Let's first look at the difference between collagen and hyaluronic acid.

Collagen and hyaluronic acid are two different substances, and the main differences are as follows:

1. Different sources: collagen is of animal origin, because collagen is extracted from animal sources, while hyaluronic acid is of non-animal origin and is produced by bacterial fermentation;

2. Different properties: collagen is a kind of protein, which is closely arranged in the dermis of the skin to maintain the contour of the skin, while hyaluronic acid is a hygroscopic agent, which will capture moisture from inside and outside the skin in the dermis, making the skin look moist and tender;

3. Different properties: the properties of collagen are white, while hyaluronic acid is transparent; Hyaluronic acid is suitable for dry skin lacking moisture, and collagen is suitable for aged and damaged skin.

4. Different correlations: Collagen has higher cross-linking property and can play a better shaping effect, but it is more difficult to inject, while hyaluronic acid has lower cross-linking property and is easier to inject;

5. Useless: Collagen can support the skin, make the face firm and the skin full, while hyaluronic acid can keep the skin smooth and moist.
