Which type of therapy uses collagen injections for skin rejuvenation?

The type of therapy that uses collagen injections for skin rejuvenation is injectable fillers. Injectable fillers are substances, often containing collagen or hyaluronic acid, that are introduced into the skin to restore volume, smooth out wrinkles, and improve the overall texture and appearance of the skin. Collagen serves as a key structural protein that helps maintain skin elasticity and hydration, making it a popular choice for aesthetic treatments aimed at achieving a youthful look.

In contrast, laser therapy utilizes concentrated light beams to target various skin issues, such as pigmentation problems or wrinkles, while microneedling involves creating tiny punctures in the skin to stimulate the body's natural healing processes and boost collagen production. Exfoliation, on the other hand, refers to the process of removing dead skin cells from the surface of the skin to improve its appearance and texture. Each of these methods has its own unique applications and benefits, but for the specific use of collagen injections in the context of rejuvenation, injectable fillers are the relevant choice.
