Allure magazine's April 2012 issue discusses anti-aging manicures. Aside from treating hands with anti-aging products (such as those containing AHAs and retinol), wearing nail polish makes the hands appear younger, according to Allure.
However, Allure warns its readers to choose color wisely.
"Blue-ish reds and whitish nudes highlight flaws like veins and spots; true reds and soft pinks are far more flattering," says manicurist Jin Soon Choi.
An extra-glossy topcoat makes hands look healthier as well.
