Among beauty seekers, collagen injection stands as a safe and effective minimally invasive procedure for rejuvenation and beautification. The material used is autologous collagen, hailed as the most technologically advanced wrinkle filler. It is crafted through the transplantation and cloning of the patient's own skin cells. Clinical cases demonstrate that patients receiving collagen injections exhibit favorable reactions and natural-looking results.The cosmetic effects of collagen injections can last up to 8 years.
I. Indications for Collagen Injections
1. Defective areas: Forehead corners, temples, glabella, nose, lips, cheeks, burn scars, traumatic injuries, etc.
2. Wrinkles: Glabellar lines, forehead wrinkles, crow's feet, nasolabial folds, jawline lines, etc.
3. Post-traumatic or disease-related depressions: Acne scars, pitted scars from sores.
II. Collagen Injection Procedure
First, a small skin sample is taken from behind the patient's ear. After cryopreservation, it is sent for preparation and cultured in a laboratory for 6 weeks.A skin test is performed on the wrist. If no allergic reaction occurs, collagen injection can proceed after two weeks.
The resulting mixture of fibroblasts and collagen is injected into the patient's face to stimulate the body's own collagen regeneration, thereby slowing skin aging. However, note the preparation's shelf life: it must be used within 24 hours after opening, with 95% fibroblast viability.
After 48 hours, 85% of fibroblasts remain viable. By 72 hours, only 65% of cells survive. The injection site should be cooled with an ice pack post-procedure. The formulation is injected using a 7-gauge needle into the superficial or mid-dermis, or at the dermal-subcutaneous junction.For deep depressed scars with Mongolian spots, subdermal incisions are required. This formulation can be injected 14-21 days post-incision. Collagen can be co-administered with botulinum toxin or sequentially with bovine collagen to prolong efficacy.
III. Advantages of Collagen Injection
Collagen injection alone can correct perioral wrinkles and fill deep nasolabial folds. Combining it with laser therapy enhances results. Co-administration with bovine collagen prolongs efficacy: bovine collagen initially provides filling, followed by collagen secreted from autologous fibroblasts.
However, during collagen injections, the two substances must not be injected simultaneously. Bovine collagen should be injected first, followed by collagen injections after a 1-2 week interval.
IV. Precautions for Collagen Injections
1. Patients undergoing collagen injections must discontinue medications such as vitamin E and corticosteroids.
2. Oral vitamin C may be administered, while topical applications of succinylcholine or vitamin C creams are permissible.
3. This therapy is contraindicated for patients with allergic conditions, cancer, prior tissue transplants, or those undergoing hormone therapy.
4. Collagen injection therapy yields optimal results for post-acne depressed skin lesions.
5. For individuals over 60 years old, collagen injection results are suboptimal due to diminished collagen-producing capacity of their skin fibroblasts. Editor's Note: Collagen injection therapy, a cutting-edge cosmetic procedure, fulfills countless dreams of beauty enhancement. Through collagen infusion, skin achieves a smooth, refined texture as if reborn.
