Background: The aim of this study was to determine whether eyebrow and eyelash whitening is an effective parameter in age estimation.
Material/Methods: We evaluated 1545 patients. Age groups were 1-10, 11-20, 21-30, 31-40, 41-50, 51-60, 61-70, 71-80, and 81-90 years. Level of whitening was categorized as level 0: no whitening, level 1: 1-3 strands, level 2: 3-10 strands, level 3: 10 strands-2/3 whitening, level 4: >3/4 whitening.
Results: Mean age was 42.39 +/- 20.01. While there was no eyebrow whitening in 87% of the subjects, level 4 whitening of eyebrows was observed in 0,8% of the subjects. There was no eyelash whitening in 97,7% of the subjects and no level 4 eyelash whitening was detected in any subject. Men had significantly more level 1, 2, 3, and 4 eyebrow whitening compared with women. There was no gender difference in terms of eyelash whitening level. There was no eyebrow and eyelash whitening in subjects age 1-40 years; whitening began in the 41-50 years age group and increased with age in other groups. Mean age was 39.59 +/- 19.63 years in subjects with no eyebrow whitening; 59 years in level 1, 61 years in level 2, 63 years in level 3, and 69 years in level 4 eyebrow whitening. Mean age was 41.85 +/- 19.87 in subjects with no eyelash whitening; and 63.57 +/- 10.75 in those with whitening.
Conclusions: Particularly after 41-50 years of age, level of eyebrow and eyelash whitening may be among a useful age estimation parameter.
