Mesotherapy : hyaluronic acid injections in Geneva
Stretch marks and scars : mechanism
Stretch marks appear when the skin undergoes excessive, sudden tension. They correspond to rupture of collagen and elastin fibres in the deep dermis, followed by partial healing that leaves streaks initially red or purple, then white and atrophic.
Scars result from a repair process after skin injury. Their appearance varies according to the origin of the trauma, skin quality and type of healing (normal, hypertrophic, keloid, atrophic).
In both cases, dermal structure is altered in the long term. This is not simply a hydration imbalance or surface defect. mesotherapy therefore cannot “erase” or reconstruct these lesions.
Mesotherapy for treating stretch marks and scars
Through superficial injections of non-cross-linked hyaluronic acid, vitamins, peptides and antioxidants, mesotherapy does not act deeply on fibrous or scar lesions.
However, it can provide an indirect benefit by :
- Improving local hydration, making tissues more supple.
- Restarting microcirculation, stimulating oxygenation and cellular metabolism.
- Slightly increasing skin density through fibroblast stimulation.
- Optimising skin receptiveness to other treatments, such as fractional lasersablative laser PRX-T33 peel or radiofrequency.
Thus, although mesotherapy does not treat stretch marks or scars, it can play a supportive role within a comprehensive protocol.
Subtle results, noticeable but limited
In some patients, particularly with recent (pink) or mild stretch marks, mesotherapy may give the impression of slight improvement : the skin seems smoother, more even and less dry. The same applies to certain acne scars or surgical scars, which may appear visually reduced after a few sessions.
However, these effects are moderate and superficial, vary greatly between patients and cannot replace treatments specifically designed to act on deep lesions.
Which treatments are genuinely effective against stretch marks and scars ?
To achieve significant results on scars or old stretch marks, other treatments are necessary, often in combination ;
- Non-ablative fractional laser, which stimulates deep dermal remodelling.
- Radiofrequency, which restarts neocollagenesis.
- PRX-T33 peel, which promotes skin regeneration and improves texture.
- Appropriate chemical peels, particularly for pigmented or irregular-looking scars.
- Injections of Skinboosters or PRP, according to indications.
Within these protocols, mesotherapy can be performed beforehand to improve tissue quality or as maintenance to prolong results.
When can mesotherapy be indicated for a scar or stretch mark ?
Mesotherapy can be used in various clinical contexts, provided it forms part of a comprehensive treatment strategy. It is particularly relevant for maintenance after more intensive treatments such as peels or lasers, helping rehydrate the skin in the long term and consolidate the results achieved.
In young patients with recent stretch marks, it may be considered an adjunctive treatment within a preventive approach to support skin changes and limit worsening. It also forms part of protocols for weakened, dehydrated or insufficiently vascularised skin by locally providing elements needed to restore tissue balance and restart cellular activity.
However, it must be considered for what it is : a complementary treatment. Alone, it cannot correct established skin lesions.
Conclusion : mesotherapy for scars and stretch marks
Mesotherapy is an effective revitalisation technique that acts on skin radiance, hydration and quality. However, it quickly reaches its limits with the structural lesions characterising stretch marks and scars. It alters neither stretch mark depth, scar pigmentation nor the fibrous texture of scar tissues.
Mesotherapy's role is clearly defined : it can support a reparative protocol and improve its tolerance or longevity, but does not constitute a standalone treatment for stretch marks or scars.
A medical consultation is essential to establish a precise diagnosis, analyse the nature of the lesions and define appropriate care. This may combine several complementary treatments, among which mesotherapy may have a place.
