Q: As I age, the circles under my eyes are becoming darker. Any suggestions?
A: This can be caused by excessive sun exposure and hormonal changes. Using an eye cream containing a safe bleaching agent, such as hydroquinone or kojic acid, can help lighten dark circles. Make sure the cream contains at least SPF 15 to prevent further sun-induced darkening. You might also try using a creamy concealer with a yellow undertone to camouflage.
