Information on collagen injections
A collagen injection (called “kolajen aşısı” in Turkish) is the injection of small amounts of a product containing animal-derived type I collagen into the skin. In our clinic, Nithya (a product containing type I collagen) is used for this purpose. Despite the popular name, it is not a vaccine. The product aims to support the skin's structural framework and skin quality.
Treatment details
Duration: About 20–30 minutes.
Who it is for: Adults with fine lines or reduced skin quality, including thin-skinned areas such as around the eyes and the neck, whose allergy history is suitable.
Number of sessions: Depending on the product protocol, usually several sessions, 1–4 weeks apart. The final plan is set by the physician after the examination.
Allergy assessment
Because animal-derived collagen products carry a risk of allergic reaction, allergy history is reviewed in detail beforehand and a pre-test is done if considered necessary. It is not used in people with a known allergy to collagen or to bovine or porcine products.
Evidence and expectations
Collagen-containing injections have been used for many years; however, large independent studies with current products are limited. The effect is temporary and varies between people.
Possible risks
Redness, swelling and bruising may occur at injection points. Less commonly, allergic reaction, nodules or infection may develop.
Who may not be suitable?
Allergy to collagen or to the product's source, a history of autoimmune disease, active infection, pregnancy and breastfeeding are assessed separately.
Frequently asked questions
Are collagen injections the same as biostimulators?
No. Collagen injections contain collagen itself; biostimulators aim to stimulate the body's own collagen production.
Is an allergy test needed?
Allergy history is always reviewed for animal-derived products; the physician performs a pre-test if needed.
Is the effect permanent?
No. The effect is temporary and its duration varies between people.
