If you're after a youthful and healthy glow without a face full of makeup, the best way to achieve that dewy glow is with a creamy blusher - which will add a little bit of colour to your cheeks.
Cream blushers are probably the better option out there compared to their powdery counterparts, not only are they easier to blend into skin and with other products - if you suffer with dry skin, it's perfect for not looking flaky throughout the day.
For the days when you can't be bothered to apply a full face of makeup, a little bit of foundation along with some a hint of blusher will give you that natural, glow you're wanting.
