How do lip injections work?
Hyaluronic acid is a molecule naturally present in the dermis, joints and cartilage. Thebody produces it naturally to renew skin tissue and moisturize the skin.
The injectable hyaluronic acid used in aesthetic medicine and cosmetic surgery is identical to that produced by the body, and is obtained through biotechnological processes. It is now widely used and recognized for its cutaneous tolerance and natural-looking properties . It is an absorbable product and its injection is different from botulinum toxin injection, but the treatments are complementary. Hyaluronic acid is very often used in combination with botulinum toxin to obtain the best possible results as part of a global approach.
What are the indications?
With age, sun and smoking, lips tend to lose volume, definition and firmness, which can lead to a thinner, more wrinkled appearance. Lip injections are a non-surgical technique for increasing volume, redefining contours and smoothing fine lines and wrinkles around the lips. Hyaluronic acid injections hydrate and nourish the lips, giving them a younger, smoother, fuller appearance.
These injections can also be performed on young lips to enhance their shape, appearance and hydration (a technique known as “Russian lips”).
Injection of hyaluronic acid therefore makes it possible to :
- Contour the lips
- Redefining the Cupid’s bow
- Increase lip volume for better symmetry
- Moisturize lips
- Reduce the appearance of fine lines above the upper lip

Frequently asked questions
How long does the result of a lip injection last and is it immediate?
The lip area is a highly stressed zone. We therefore use high-quality hyaluronic acid with high density (cross-linking) to ensure lasting results. Results from hyaluronic acid injections in the lips last around 8 to 10 months, depending on the individual and lifestyle.
Results are immediate, although some patients may experience slight swelling or bruising at the injection site, which may take a few days to resolve. Definitive results generally appear within a few days of treatment, once lip swelling and bruising have disappeared.
Is it painful?
The area’s strong innervation provides good contact analgesia. An anaesthetic cream is therefore applied beforehand. In addition, the filler contains lidocaine, a powerful anesthetic agent, to minimize discomfort. These injections are therefore well tolerated.
What are the contraindications to lip injections?
Lip injections are not recommended for pregnant or breast-feeding women, people with active infections around the lips and people with a history of allergies to any of the components used.
What are the possible complications?
- Edema, ecchymosis, redness, itching or pain at the injection site. These effects are transient.
- Asymmetry: a further injection may be performed in the following days to correct any asymmetry.
- Granuloma (inflammatory nodule)
- Infection (very rare)
- Allergic reaction (very rare)
- Necrosis (very rare)
To minimize these risks, it is essential to consult a qualified and experienced physician. At Claris Clinic, only specialized doctors perform injections. We work with hyaluronic acid brands offering the best quality guarantees.
How much does a lip injection cost?
Depending on the doctor, the consultation fee ranges from €50 to €70. Injections start at €245, depending on the area to be treated and the quantity to be injected. These prices are indicative and include VAT. The precise estimate will be drawn up by the doctor during the consultation.
