Mesotherapy : hyaluronic acid injections in Geneva
Mesotherapy : targeted injection of active ingredients into the dermis
Mesotherapy involves injecting small amounts of active substances selected according to the indication into the superficial dermis using very fine needles.
These injections can be performed manually or with a high-precision electronic injector (such as a latest-generation gun). Injected ingredients are personalised mixtures containing non-cross-linked hyaluronic acid, vitamins (A, C, E, B5), amino acids, coenzymes, antioxidants, trace elements or biomimetic peptides.
The aim is to deliver the elements skin cells need directly to them at a depth cosmetics cannot reach. By stimulating fibroblast activity, mesotherapy restarts natural production of collagen, elastin and hyaluronic acid.
Microneedling : mechanical skin stimulation
Microneedling relies on a completely different principle : deliberately creating skin microperforations using a roller or automated pen fitted with microneedles.
These microchannels, invisible to the naked eye, trigger a natural healing mechanism during which the skin repairs itself by producing more collagen and elastin. This mechanical stimulation slightly improves skin texture, enlarged pores and tone.
In some cases, a serum or nutritional complex is also applied during treatment, but without active injection into the dermis. This is not an infusion of ingredients as in mesotherapy, but rather controlled dermal stimulation.
Objectives and indications of mesotherapy and microneedling
Mesotherapy hydrates and nourishes ; microneedling regenerates.
Mesotherapy is recommended when the skin needs deep hydration, renewed radiance, preventive anti-ageing action or consolidation after more intensive treatments such as laser, peels or radiofrequency.
Microneedling is more indicated for loss of skin tone, enlarged pores or skin surface irregularities.
These two techniques can be combined in a comprehensive protocol : microneedling for mechanical stimulation and mesotherapy for biological stimulation.
Mechanisms of action of mesotherapy and microneedling
Mesotherapy relies on biological action : injecting small amounts of active ingredients — hyaluronic acid, vitamins, peptides — into the superficial dermis, directly within skin tissue.
Microneedling acts mechanically : fine needles create controlled microperforations in the epidermis and mid dermis, triggering a natural healing response that stimulates collagen production.
Their objectives also differ : mesotherapy aims to hydrate the skin deeply, improve complexion radiance and prevent signs of ageing. Microneedling is more indicated to improve skin texture, smooth irregularities and tighten pores.
In terms of duration, a mesotherapy session is generally shorter — between 15 and 30 minutes — while microneedling lasts 30 to 45 minutes according to the treated area and selected intensity.
The mesotherapy protocol generally comprises between three and five sessions complemented by occasional maintenance. Conversely, microneedling requires an average of six to ten sessions according to the indication and desired objectives.
Regarding tolerance, mesotherapy involves little pain : sensations remain moderate and well tolerated, making anaesthetic cream rarely necessary. However, microneedling may cause more pronounced discomfort ; in this case, prior application of anaesthetic cream is almost systematic.
Recovery also differs between the techniques. After mesotherapy, slight redness may appear but generally fades within a few hours without social downtime. Microneedling may cause more diffuse redness and a more prolonged feeling of warmth, potentially requiring 24 to 48 hours of recovery according to treatment intensity.
Finally, mesotherapy results appear gradually and are often visible from the second session. Microneedling results appear later, generally after two to three weeks once skin regeneration has begun.
How should you choose between mesotherapy and microneedling ?
The decision to perform microneedling or mesotherapy never rests on personal preference, but on rigorous clinical analysis. The choice depends on skin type, the main indication, patient's age, injection tolerance and possible combination with other treatments (Skinboosters, peels, LEDs...).
In many cases, these techniques can be alternated or combined to act at several levels : dermal structure on one hand (mesotherapy) and mechanical remodelling on the other (microneedling).
Conclusion : mesotherapy and microneedling
Mesotherapy and microneedling are complementary tools, each providing a specific response to an identified skin need. Mesotherapy gently nourishes, hydrates and revitalises ; microneedling triggers deeper structural regeneration useful for correcting irregularities and improving firmness.
These treatments always form part of comprehensive, personalised care designed to respect skin identity, optimise skin quality and support ageing appropriately.
