Mesotherapy is one of the most popular aesthetic treatments for people who want to improve skin quality, tackle sagging or treat localised fat without invasive procedures.
However, as with many popular techniques, it also raises questions and concerns — especially about safety.
So, is mesotherapy dangerous? Or are the risks more about where it is done and who does it? In this article we clear up the myths and facts about the dangers of mesotherapy, explain when complications can occur and show why, when performed correctly, it is an effective, very low-risk treatment.
If you are considering this aesthetic treatment in the Algarve, at Atelier do Sorriso we follow strict protocols for complete safety and natural results. Read on to find out how mesotherapy works, what care it requires and why we are a reference for this technique in the region.
What Is Mesotherapy and How Does It Work?
How the treatment works and what it is for
Mesotherapy is a minimally invasive aesthetic treatment that uses intradermal micro-injections of specific substances directly into the area being treated. The aim is a localised action promoting cell regeneration, deep hydration, firmer skin and even reduction of localised fat, depending on the formula used.
It is used for both facial rejuvenation and body treatments, and is sought by patients who want to:
- Reduce sagging and fine lines;
- Improve skin texture and radiance;
- Treat cellulite and localised fat;
- Redefine facial contours;
- Stimulate collagen and elastin naturally.
Types of substances used
The substances used vary according to the goal of the treatment and are chosen after a personalised assessment. The most common at Atelier do Sorriso are:
- Hyaluronic acid: to hydrate and firm the skin;
- Vitamins and amino acids: to revitalise the skin;
- Lipolytic enzymes: for localised fat under the chin or on the body;
- Antioxidants: to fight the effects of premature ageing.

The Supposed Dangers of Mesotherapy
Adverse reactions and inflammation
Although mesotherapy is considered a safe, well-tolerated procedure, there are many exaggerated reports and generalisations online about its risks. As with any procedure involving the skin, temporary effects such as redness, swelling or small bruises may appear at the injection sites — especially in the first 24 to 48 hours. These reactions are usually mild and go away without treatment.
More serious inflammation or infection is extremely rare and, when it happens, is usually linked to poor hygiene, uncertified products or injections by insufficiently qualified practitioners.
Problems caused by non-specialist clinics
Most of the risks attributed to mesotherapy come from treatments carried out in places without clinical authorisation, without proper hygiene protocols and often without trained health professionals. In these cases, low-quality or poorly stored substances, or injections in the wrong areas of the face or body, can compromise the result and cause complications.
The difference between a complication and an injection error
It is essential to distinguish between a possible complication (such as an individual allergic reaction, even with approved substances) and an injection error — which can be completely avoided with training, technique and clinical responsibility.
At Atelier do Sorriso we explain all the risks and precautions before starting treatment and carry out an individual medical assessment, significantly reducing any chance of unwanted effects.
Why Is Mesotherapy Safe When Done Properly?
The practitioner’s training and experience
The main factor in mesotherapy safety is the qualification of the person performing it. When the procedure is carried out by a health professional trained in aesthetic medicine and facial harmonization, the risks are minimal. They will assess your skin type, medical history and specific aesthetic needs, adjusting the technique and formula for effective, safe results.
Clinical environment and hygiene standards
Another critical point is where the treatment is performed. Regulated clinics such as Atelier do Sorriso strictly follow all biosafety standards, with disposable materials, disinfection between patients and rigorous control of where products come from.
Mesotherapy performed in unauthorised places or without clinical supervision can significantly increase the risk of infection, allergies or unsatisfactory results.
Protocols used at Atelier do Sorriso
At Atelier do Sorriso, in Almancil, in the centre of the Algarve, we only use substances approved by European regulators, from recognised aesthetic brands with proven effectiveness. Our protocols are tailored to each patient and can include modern equipment such as the Fotona laser, which boosts the absorption of active ingredients and reduces discomfort during the procedure.
We combine personalised assessment, certified products and an excellent clinical environment for safe, comfortable mesotherapy with visible results.
Benefits of Safely Performed Mesotherapy
Firmer skin with better texture
When performed by qualified professionals, mesotherapy visibly improves skin firmness and texture. The micro-injections act directly in the deeper layers of the dermis, providing intense hydration and stimulating collagen and elastin. The result is younger-looking, toned and radiant skin.
Gradual, natural results
One of mesotherapy’s great strengths is that the results are gradual and natural. Unlike invasive techniques or immediate fillers, it works gradually, respecting the body’s response time. This gives subtle, progressive improvements, ideal for anyone who wants rejuvenation without drastic changes.
A minimally invasive, effective procedure
The technique is minimally invasive, using fine needles and with no recovery time. Most patients return to their normal activities straight after the session. Combining it with technologies such as the Fotona laser can further enhance the results with less discomfort and a lower risk of side effects.
