New season, *another* new foundation shade? Think again. This is your sign to stop investing in multiple foundation shades to suit your tannest self in the peak of summer or fairest self in the chill of winter – and all the seasons in between. Instead, just buy two foundation shades matching the lightest and darkest that you usually tend to get and mix them to create your perfect match all year round. Pro tip: This is a great way to use up those half-empty foundation bottles that don’t match you anymore.
