Subjective Evaluation of the Results of Injectable Hyaluronic Acid Fillers for the Face

Background: Skin ageing is a physiological process, progressive and irreversible. Hyaluronic acid injection treatments are used to correct the signs of skin ageing. Material and Methods: Hyaluronic acid was implanted in the area of the cheek and the forehead aesthetic units in 57 women, aged 35-55 years. Apart from the clinical observation, self-assessment of the therapeutic results was conducted. The "My skin" questionnaire was used for subjective evaluation of the treatment results. Results: Mean wrinkle score in the pre-menopausal group changed after the treatment, from 3.2+/-0.6 to 1.1+/-0.3 and from 3.2+/-0.6 to 0.8+/-0.6 for the forehead and the cheek esthetic units, respectively. In the post-menopausal group, the score decreased from 3.8+/-0.4 to 1.7+/- 0.7 and from 3.2+/-0.617 to 0.8+/- 0.6 for the forehead and the cheek esthetic units, respectively. The changes were age-dependent. Improved appearance of the facial skin - higher satisfaction with skin tone and scent - was reported after hyaluronic acid injections. Higher subjective perception of improvement corresponded to older age, irrespectively of the menopausal status. Correlations between age and the effect of the treatment on maintaining proper skin hydration as well as between improved appearance of the forehead area and feelings of autonomy and well-being were found. Conclusion: Hyaluronic acid injections significantly improved the subjective perception and overall assessment of the scent and appearance of the facial skin.
