What Are Collagen Injections and How Do They Work?

Collagen injections can restore volume to the face when collagen decreases with age

Collagen is a protein naturally found in the skin, which gives it strength, elasticity, and a youthful appearance. As we age, collagen production decreases, resulting in fine lines, wrinkles, and volume loss. While there are many treatments that help stimulate collagen, one direct approach is through collagen injections. At Jaibaji Plastic Surgery in San Diego, collagen-based fillers are among the options Dr. Moneer Jaibaji uses to restore facial volume and enhance skin texture in a natural-looking way.

How Do Collagen Injections Work?

Collagen injections involve placing purified collagen directly into areas of the face where volume has been lost or wrinkles have developed. The collagen fills in these areas immediately and also stimulates the body’s natural collagen-building response over time.

There are several types of collagen fillers available. Some are derived from bovine sources and require allergy testing, while others are formulated with synthetic or bio-stimulatory materials like poly-L-lactic acid (as in Sculptra) to gradually build collagen from within.

In general, collagen injections are used to:

  • Soften smile lines and nasolabial folds 
  • Restore volume in the cheeks and jawline 
  • Improve lip definition 
  • Minimize the appearance of shallow scars

What Makes Collagen Fillers Different from Other Fillers?

Most modern dermal fillers are composed of hyaluronic acid, a substance that attracts moisture and adds volume. While these are excellent options for many patients, collagen-based fillers offer a different mechanism, encouraging the natural regeneration of the skin’s underlying structure.

Collagen injections may be preferred by patients seeking a more gradual improvement or those who desire results that appear subtle and evolve over time. In some cases, they are used as part of a broader facial rejuvenation strategy alongside hyaluronic acid fillers, Botox, or fat transfer.

How Long Do Results Last?

Collagen injections typically last between three and six months; however, some biostimulatory formulations can produce results that continue to improve for several months after treatment. Maintenance sessions can prolong the effects and encourage ongoing collagen renewal.

Is There Downtime After Collagen Injections?

Most patients experience little to no downtime. Minor swelling or bruising at the injection sites is possible but typically resolves within a few days. Dr. Jaibaji employs precise techniques to achieve natural-looking results with minimal discomfort.
