Mesotherapy refers to the intradermal or subcutaneous micro-injection of active substances — vitamins, amino acids, minerals, hyaluronic acid, or lipolytic agents — directly into the target tissue layer, on the premise that local delivery achieves a higher concentration at the site of action with lower systemic exposure than oral or intravenous routes.
Facial mesotherapy (biorevitalisation)
Facial mesotherapy protocols typically use low-molecular-weight or non-crosslinked hyaluronic acid, often combined with vitamins, amino acids, and antioxidants, delivered via multiple micro-injections or micro-needling devices across the treatment area. Evidence for improvement in skin hydration and texture is reasonably consistent across published studies, though study quality varies and formulations are rarely standardised between manufacturers, which complicates direct evidence comparison — a point worth making explicitly to students who will encounter marketing claims that outstrip the underlying literature.
Body mesotherapy and lipolysis
Body applications, particularly for localised fat reduction (using agents such as deoxycholic acid derivatives) and cellulite treatment, sit on a considerably weaker evidence base than facial biorevitalisation. Deoxycholic acid has the most substantial clinical trial support among lipolytic agents, having undergone rigorous trials for submental fat leading to regulatory approval in several jurisdictions; results for other body areas and for many combination 'fat-dissolving' cocktail formulations are far less rigorously supported and should be presented to students with appropriate evidentiary caveats.
Injection technique and depth
Protocols generally specify depth by target: superficial dermal (papular technique, very small blebs, used for fine surface texture); deep dermal (nappage/fanning technique, used for broader biorevitalisation); and subcutaneous (used for lipolytic and larger-volume delivery). Needle or cannula choice, injection angle, and spacing between puncture points are all protocol-specific and should be taught with reference to the product's own instructions for use rather than as universal defaults.
Safety and hygiene considerations specific to mesotherapy
- High puncture density raises infection risk relative to single-point filler injections — strict aseptic technique is non-negotiable.
- Multiple small blebs can mask early signs of vascular compromise; students should be trained to recognise blanching or unusual pain even in a technique perceived as 'lower risk.'
- Combination cocktails compound allergy and interaction risk — every component's safety profile must be individually understood, not just the branded product as a whole.
