Background: Telangiectasia or red veins are one of the prominent features of facial skin ageing. To date, there are few studies investigating the determinants of telangiectasia.
Objectives: We investigated lifestyle and physiological factors associated with facial telangiectasia in a large prospective Dutch cohort study.
Methods: Telangiectasia was quantified digitally from standardized facial photographs of 2842 North European participants (56.8% female, median age 66.9) from the Rotterdam Study, collected in 2010-2013. Effect estimates from multivariable linear regressions are presented as the percentage difference in the mean value of telangiectasia area per unit increase of a determinant (%Δ) with corresponding 95% CI.
Results: Significant determinants were older age [1.7%Δ per year (95% CI 1.4, 2.0)], female sex [18.3%Δ (95% CI 13.2, 23.6)], smoking [current versus never 38.4%Δ (95% CI 30.3, 47.0); former versus never 11.6%Δ (95% CI 6.6, 16.9)], a high susceptibility to sunburn [10.2%Δ (95% CI 5.4, 15.3)] and light skin colour [pale versus white-to-olive 31.4%Δ (95% CI 19.7, 44.1]; white vs. white-to-olive 9.2%Δ (95% CI 2.8, 16.0)].
Conclusions: In this large cohort study, we confirmed known and described new determinants of facial telangiectasia.
