“…In clinical practice, various methods have been attempted to achieve a more quantitative facial evaluation, including the cephalometric technique, which allows quantitative analysis of the NLF, serving as a parameter for facial symmetry evaluation. 13,14 Some facial assessment studies have already made use of this type of facial symmetry analysis. In these studies, the technique has proven to be an effective parameter in the evaluation process, identifying a reduction in the angle and an increase in the length of the fold, findings that are associated with the chronological aging process.…”

Objective: To evaluate the facial aging of women of different ages using a software program to assist in the classification of wrinkles and sagging in the nasogenian region. Method: A descriptive observational study of 100 female volunteers was performed. The women were aged between 20 and 70 years old and were sorted by age group into five groups of 20 volunteers each. The instruments used were the Facial Assessment Protocol, a cephalostat for the standardization of photos, a 14.1 megapixel Sony digital camera, and the Radiocef 2.0 ® software program. The Kolmogorov-Smirnov (KS) test was used for confirmation of normality and all data was statistically analyzed using ANOVA and Tukey's post hoc analysis. The Chi-squared and Pearson's correlation tests were also performed. A significance level of 5% and a p value of ≤0.05 were adopted. Results: It was observed that all age groups had wrinkles in the nasolabial fold region. There was an association between age and the Goglau, Lapiere and Pierard scale. This incidence increased progressively with aging. A moderate correlation (r=0.67) was observed between age and distance from the nasolabial folds, while angle represented only a weak correlation (r=0.3), with the most significant age group that with the shortest distance and the widest angle. Conclusion: The present study demonstrated the importance of the Radiocef 2.0 ® software program in providing a more detailed analysis of the nasolabial folds. It is therefore a complementary assessment to the Facial Assessment Protocol, representing a research protocol for identifying the effectiveness of treatments and improving the evaluative procedure.

“…The two most common methods utilised for face wrinkle measurement involve the use of skin casts or skin replicas [1,[8][9][10] or the use of images [1,[10][11][12][13][14][15][16][17]. Biopsies [11,18,19], direct 3D invivo measurements [20] and elasticity measurements using a cutometer [8,10,21] have also been employed and a few studies utilised depth, number or length measurements for wrinkle quantification [12,14,19,22].…”

“…descriptive, visual analogue and photographic scales. Most of these scales are intended for assessment of specific body regions, such as cheek sagging, crow's feet [1], nasolabial folds [2], lip fullness [3], marionette lines [4], forehead wrinkles [5] while a few are intended for the entire face [6]. The drawback of these scales is that the quality of scoring is strongly influenced by the level of experience of the examiner as the assessment is based on a subjective visual perception of lines and wrinkles rather than actual physical measurements.…”

Increased demand for treatment of skin wrinkles has led to a proliferation of different pharmaceutical and surgical treatment methods. However there still remains a lack of quantitative, objective, easily utilizable and reproducible wrinkle classification system by which these treatments can be studied and compared. We propose the use of a novel photometric stereo based technique as a potentially efficient and economical way for quantitative evaluation of skin topography. Also presented is an algorithm for improving depth estimates of skin using photometric stereo and Fractals based technique for quantification of skin topography which unlike existing 2D roughness parameters makes use of complete 3D topographical information.
