Scientific research indicates collagen is a high-molecular-weight protein. Its fibrous structure maintains skin firmness and elasticity, constituting one-third of the body's total protein. It serves as both the structural framework of life and the foundation of beauty, imparting smoothness, hydration, resilience, and a youthful radiance to the skin.
Regrettably, collagen begins to diminish in women from the age of 20 onwards.The peak loss occurs around age 25, and by age 40, collagen levels drop below half of what they were at age 18. This depletion causes the collagen peptide bonds and elastic network supporting the skin to break down, disrupting its spiral mesh structure. Consequently, skin tissue rapidly atrophies, sags, and collapses, leading to the emergence of wrinkles...
Characteristics of Collagen Injections for Wrinkle Reduction
Numerous injectable wrinkle reduction methods exist today, typically named after the injected material—such as Evlan injections, hyaluronic acid injections, or Aibei injections. Their most notable feature is immediate results, a key reason why many beauty enthusiasts favor this technique.Different materials exhibit distinct effects. Collagen is an essential component for maintaining normal bodily functions. It also plays a crucial role in preserving youthfulness and preventing aging. However, as we age, collagen in the skin gradually breaks down and diminishes. This loss of support causes the skin surface to sag, leading to wrinkles and laxity.
When medical-grade collagen is injected into depressed skin defects, it not only provides structural support and filling but also stimulates the body's natural tissue regeneration. The newly formed tissue integrates harmoniously with surrounding healthy skin, achieving corrective effects that restore normal appearance and eliminate wrinkles.
Duration of Post-Injection Results
Since collagen is naturally present in the body, its relatively rapid absorption affects the longevity of wrinkle-reduction effects. The exact duration of collagen injection results remains uncertain, typically lasting between 9 to 12 months.
If dissatisfied with the outcome, a touch-up injection can be administered after six months to enhance results or extend the effect duration.Normal work and study activities can resume immediately after the procedure. No recovery period is required as long as the doctor's post-treatment instructions are followed.
Injection Specialist Explains the Collagen Injection Process
Step 1: Allergy Testing
Based on the type of collagen filler selected by the patient and doctor, an allergy test must first be conducted. This is typically performed one month prior to the injection treatment.During the test, a minute amount of the filler is injected, followed by observation for swelling, redness, itching, or other abnormal reactions at the injection site. Immediately notify the doctor if any of these reactions occur. Step 2: Assessment The doctor evaluates the patient's appearance and skin condition, considering their desired treatment outcomes, and examines the areas to be treated.
Step 3: Marking Injection Points
Injection points are marked on the patient's face to guide precise placement of the filler during treatment.
Step 4: Cleaning the Injection Site
After cleansing the area with antiseptic, local anesthesia is applied. However, collagen injectables sometimes contain anesthetic agents already.
Step 5: Injection
The actual injection takes only a few minutes total, with each site requiring just seconds.
Step 6: Cleanup and Ice Application
After removing facial markings, ice is applied to alleviate mild, temporary discomfort. Patients may apply makeup at this stage but must avoid pressing the treated area to prevent displacement of the newly injected collagen.
Special attention is required when treating scars and deeper wrinkles. Multiple injections in the problem area are typically necessary to achieve optimal results. When deeper subcutaneous injections are needed—such as for nasolabial folds, marionette lines, or cheek augmentation—local anesthesia is usually administered to ensure patient comfort.
Collagen Injection Techniques:
1. Needle Insertion: The practitioner holds the collagen syringe in the right hand while the left hand tenses the skin. The needle should be inserted along the direction of the wrinkle at a 15° angle to the skin surface. The beveled tip should be directed upward as it slowly enters the end of the wrinkle or the deficient dermal layer. Avoid injecting collagen into small subcutaneous blood vessels.However, inserting the needle too shallowly may also puncture the skin, causing collagen to leak out during injection.
2. Injection: Once the needle is fully inserted into the dermal layer, begin injecting while slowly withdrawing the needle. Continue injecting as you withdraw, aiming for the most even distribution possible.The injected area should exhibit skin whitening and elevation. If skin color remains unchanged, this indicates excessive needle depth; withdraw the needle and reinsert it.Excess collagen volume will dissipate within approximately 24 hours. Typically, a second injection is administered 2-4 weeks after the first. Depending on wrinkle depth and depression severity, an average of 2-3 injections achieves the desired outcome. Generally, 0.2-1.0ml is injected per session based on defect size, though 1-2ml may be administered in specific cases. The maximum annual collagen injection volume for adults should not exceed 30ml.
4. Massage: Gently massage the treated area after collagen injection to ensure even distribution of the collagen beneath wrinkles and depressions.
Collagen plays a vital role in skin health, yet its levels decline sharply in adults, leading to gradual skin aging. Timely and effective replenishment of lost collagen is crucial for addressing premature skin aging.Who are the most suitable candidates for collagen injections?
Risks and Complications of Collagen Injections
1. Non-inflammatory reactions may include temporary swelling, mild redness, or slight discomfort, typically subsiding within 24-48 hours.
2. Localized bruising (ecchymosis) is uncommon, may persist for 1-2 weeks, and usually resolves spontaneously.
3. Over-injection: Seek immediate medical attention. Mild cases may require only prompt treatment by a doctor, while severe cases necessitate removal of the injected material. Removal procedures are more complex than injections; thorough preoperative discussion with your doctor is essential.
4. Pigmentation: Occurs when injections are too superficial or sun protection is neglected. Apply whitening masks 4-6 times after one month to reduce or eliminate pigmentation.
Ideal candidates for collagen injections:
1. Individuals with poor skin quality, oiliness, dullness, acne scars, or hyperpigmentation due to hormonal imbalances;
2. Those experiencing dry, lifeless hair, brittle nails, joint strain, or breast sagging caused by hormonal imbalance;
3. Individuals with skin sensitivity, dense blackheads, or extensive skin damage caused by low-quality cosmetics or improper cosmetic use;
4. Those frequently exposed to computer screens or polluted air; individuals with irregular diets or a preference for fried foods; women with high standards for their appearance;
5. Those with skin laxity, sagging, dryness, age spots, dull complexion, or melanin deposits due to aging or sun exposure;
6. Those with rough skin, fine lines (dry lines), pigmentation, dullness, laxity, premature aging, dark circles, or eye bags caused by work fatigue and insufficient sleep;
7. Individuals with excessive abnormal melanin secretion accumulating on the skin surface, leading to various pigmentation issues such as melasma, freckles, or early age spots due to impaired melanin metabolism;
8. Individuals with skin damage from prolonged outdoor exposure and improper skincare, resulting in premature wrinkles, dryness, flaking, redness, swelling, enlarged pores, and other adverse symptoms.
Pre- and Post-Injection Tips
1. Conduct a collagen allergy test 4 weeks prior to injection.
2. If inflammation exists in the injection area, wait until it has resolved before proceeding.
3. Avoid medications containing aspirin one week prior to treatment.
4. For one week after injection, avoid washing the treated area during facial cleansing or bathing. Refrain from facial masks or skin treatments and avoid consuming irritating foods.
