Aging is an increasing concern of modern society, particularly facial ageing. In recent years, the microinjection technique has increasingly been emphasised as a skin rejuvenation strategy. Hyaluronic acid (HA) plays an important role in the hydration of the extracellular space and can thus improve skin hydration, firmness and viscoelastic properties.
To evaluate the efficacy and safety of HA microinjection in skin rejuvenation.
We enrolled thirty participants underwent three sessions of HA microinjection involving multiple injections in the face or back of the hands at 2-week intervals. The aesthetic outcomes were assessed at baseline and after 2, 4 and 8 weeks. Clinical evaluation was based on the Global Aesthetic Improvement Scale (GAIS) and the Wrinkle Severity Rating Scale (WSRS).
Evaluation of photographs from 2, 4 and 8 weeks revealed significant clinical improvement in the brightness, texture and wrinkling of the skin. Analysis of the GAIS and WSRS scores revealed statistically significant results after 2 months.
Most of the participants felt satisfied with the treatment (93.3%).
