Brown mascara is perfect as an update, especially if you like brown eyeshadow, as it’ll blend in really nicely and feel lighter, less laboured.
With contour, focus on adding dimension and enhancing shape rather than making things look really angular, which feels dated now.
Bright intense blush also looks passé, with colours that look a little more pared back working really well.
You don’t need to compensate with another feature, just lean into it being less defined and obvious.
So much of make-up now is about that sense of things not being overdone.
