Cupid's bow definition
The upper lip tends to lose definition over the years. Redefining the Cupid's bow with hyaluronic acid restores structure without adding volume. The result is a younger lip, not a bigger one.

Lip enhancement and definition with hyaluronic acid to restore proportions, not to add volume by default. It also hydrates and improves lip quality. Your natural anatomy is the guide: the goal is not a bigger lip, it is a better lip.
In short
Hyaluronic acid lip filler adds volume, defines the outline and hydrates, aiming for a natural result. A 30–45 minute session, minimal downtime and results lasting 6–12 months. Price: €280, with a single syringe. Treatment is performed by Dr. Rubén Bermejo Pérez, a registered aesthetic physician (COMB no. 63226), at Clínica Sagrada Família, Barcelona.
Dr. Bermejo explains why lip filler is not about adding volume, but about respecting your anatomy.
Medical judgement
“The key is not to fill more,Dr. Rubén Bermejo Pérez
it is to assess better.”

Anatomy · Lip filler
Respect the lip, don't transform it.
The muscle around the lips that gives them shape and movement.
Defining the outline restores harmony without adding extra volume.
Fine lines above the upper lip can also be softened.
Your natural anatomy is the guide: the goal is a better lip, not a bigger one.
What it treats

The upper lip tends to lose definition over the years. Redefining the Cupid's bow with hyaluronic acid restores structure without adding volume. The result is a younger lip, not a bigger one.

When the lip has lost natural volume over time, restoring it in proportion brings back harmony to the lower face. Hyaluronic acid also hydrates the lip and improves its texture. The principle is always the same: replace, don't add.

Many patients have an upper lip that is noticeably thinner than the lower one, or a difference between sides. Filler balances these proportions in a controlled, natural way.

Lines around the mouth can be treated by combining a very superficial filler with other treatments such as botulinum toxin or biostimulation. The assessment determines the best combination.
The practical side
Everything you need to know before your consultation. No small print.
It varies with technique and metabolism. Lips last slightly less than other areas.
Includes the assessment and time for numbing cream.
Possible swelling for 24–72 h. The final result is visible after a week.
Fixed price, with a single syringe of hyaluronic acid: the amount that gives a natural, proportionate result.
Who it's for
Not sure if it's for you? That is exactly what the consultation is for: I'll tell you honestly what I see.
Free first visit · no commitment
In the consultation we look at the proportions of your face, talk about what you want and set the goals together. If you don't need treatment, I'll tell you that too.

The guide price is €280. A fixed price with a single syringe of hyaluronic acid: the amount that gives a natural, proportionate result. The first consultation is free. You can see all fees on the prices page.
Usually 6–12 months. It varies with technique and metabolism; lips last slightly less than other areas.
At Clínica Sagrada Família, C/ Torras i Pujalt 1 (3rd floor), Barcelona. It is performed personally by Dr. Rubén Bermejo Pérez, registered physician no. 63226.
The lips are a sensitive area. We apply numbing cream beforehand to minimise discomfort. Most people describe it as tolerable — more pressure than sharp pain.
The final result is visible after 7–10 days, once the initial swelling settles. For the first 24–72 hours your lips may look fuller than the final result — this is completely normal.
With the right amount and technique, no. The goal is for your lips to look more defined and hydrated, not for people to notice “you've had your lips done”. An exaggerated result almost always comes from too much product or the wrong indication.
Yes. Hyaluronic acid can be dissolved with hyaluronidase if the result is not what you expected, which makes lip filler one of the safest treatments. I explain it in detail in how a filler is dissolved with hyaluronidase.
I recommend waiting 24 hours before applying make-up to the area. For the first few hours, avoid touching or pressing the lip so the product settles properly.
One syringe at most. I don't use more on the lips: a single syringe gives a natural, proportionate result, and often less is used. The exact amount is decided at the assessment.
Before: unless prescribed by your doctor, avoid aspirin, ibuprofen and omega-3 supplements for 3–4 days to reduce the risk of bruising. After: avoid intense exercise and heat (sauna, direct sun) for the first 24 hours.
Some swelling and tenderness for the first 24–72 hours is usual, and sometimes a small bruise at the injection point; these clear on their own within a few days. While swelling goes down, slight asymmetry can show, which we check at the review. Serious complications, such as a blocked blood vessel, are very rare: that is why the treatment is done by a doctor, who knows how to recognise and treat them on the spot.
It's not a technique I usually perform. Before treating, we analyse your face, talk with you and set the goals together. We don't follow trends — we follow what suits your face and proportions.
Gentle kissing is fine after 24 hours. Intense exercise, ideally after 24–48 hours. Dental cleanings and treatments are best left for two weeks, because they keep the mouth open and stretch the lip.
Yes, with precautions. If you have an active outbreak, we wait until it clears. If you get frequent outbreaks, mention it at the assessment: in some cases a preventive treatment is prescribed before the session.
First, wait for the swelling to go down: the real result shows after a week. If you're still not happy, we review it and, if needed, the hyaluronic acid can be dissolved with hyaluronidase.
