What Is a Collagen Booster Injection?
“Collagen booster injection” (known in Turkey as a “collagen vaccine”) is a term used for biostimulator injections that aim to stimulate the skin’s own collagen production. Although the word “collagen” is in the name, the aim of this treatment is usually not to supply collagen from the outside but to encourage the skin to produce its own.
Biostimulator substances such as poly-L-lactic acid or calcium hydroxylapatite may be used for this purpose. As these substances are gradually broken down by the body beneath the skin, they trigger a repair response that supports collagen formation in the surrounding tissue. Which product is suitable is determined at the consultation according to your skin type and the target area.
Collagen is the main supportive protein that gives skin its firmness and resilience. Its production slowly declines from the twenties onward; sun, smoking, stress and lack of sleep can speed up this process. Biostimulators aim to support this slowing production, and the result appears over weeks together with the skin’s own building process.
Who Is It Suitable For?
- People who are starting to lose firmness and elasticity in their skin
- Those with a tendency toward mild sagging and thinning of the skin on the face
- Those who prefer a natural improvement spread over time to a sudden change
- Those who want to support skin quality on the neck, décolleté or back of the hands
- Those without marked volume loss, or for whom a supportive approach alongside filler is planned
In cases of marked sagging, biostimulators alone may not be enough; if needed, they are planned together with other methods.
How Is the Treatment Done?
- At the consultation, your skin thickness, degree of firmness and facial structure are assessed; a suitable biostimulator and treatment plan are determined.
- The skin is cleansed and prepared with an antiseptic. Numbing cream or local anesthesia may be used for comfort.
- The product is applied to the chosen areas with a fine needle or a cannula.
- Depending on the product used, the area may be gently massaged, and the care you need to do at home is explained.
Because collagen formation takes time, a few weeks are allowed between sessions. This period also makes it possible to assess how the skin has responded to the previous treatment.
What to Pay Attention to Afterward
- Depending on the product used, your physician may recommend that you massage the area regularly for a certain period; it is important to follow these instructions.
- It is advisable to avoid saunas, steam baths, intense exercise and excessive heat in the first few days.
- It is recommended that you do not wear makeup for the first 24 hours.
- Mild fullness seen early on is mostly due to swelling; the real change appears over weeks.
- At the follow-up visit, the skin’s response is assessed and you decide together whether the next session is needed.
Possible Side Effects and Who Should Not Have It
Swelling, bruising, tenderness and redness may be seen after the treatment. Specific to biostimulators, small lumps (nodules) that can be felt under the skin may rarely form; correct technique, appropriate product selection and following the aftercare instructions reduce this risk. Infection and allergic reactions are rare.
The treatment is not performed during pregnancy and breastfeeding, if there is an active infection or inflammation in the treatment area, in people prone to keloids, during the active phase of certain autoimmune diseases, or in case of allergy to the product’s ingredients. Use of blood thinners is assessed at the consultation.
If you notice a firm lump that you can feel in the treatment area within weeks, or if you have increasing pain, redness or warmth, you should contact your physician for a check.
Dr. Fulya Koç’s Approach
The collagen booster injection is a concrete expression of Dr. Fulya Koç’s saying, “Don’t give a fish, teach to fish.” Encouraging the skin to produce its own supporting structures instead of filling it helps results look more gradual and natural.
At the Ataşehir clinic, the biostimulation plan is created by talking through your expectations and your skin’s real needs together. It is made clear from the start that the result varies from person to person and takes time.
Patience matters in this process: the goal is that, when you look in the mirror, what you notice is healthier, more rested skin rather than the procedure itself.

Frequently asked questions
Because collagen formation is a biological process that takes time, change usually begins within a few weeks and becomes gradually more noticeable over a few months. The speed and degree vary from person to person.
The duration of the effect depends on the product used, age, skin type and lifestyle. Maintenance treatment at certain intervals is usually planned after the initial sessions.
No. Collagen supplements taken by mouth are a nutritional support. A collagen booster injection, on the other hand, is a medical procedure applied to the skin that aims to stimulate the skin’s own collagen production.
