If you can see where you're going outside, you need sunscreen. Layer over moisturizer and under make up for the best protection against future damage.

Liver spots
I'm only 27, but I've got some serious 'liver spots' on my cheekbones. Does this mean I'm more apt to age quickly?

No, and yes. 'Liver spots' are actually signs of sun damage (which leads to premature ageing) and show up in areas where the melanocytes in your skin have been overstimulated by UV radiation. A multitude of lightening ingredients can help repair them, but daily use of an SPF (15+, please) is your best bet for anti-ageing prevention. Good luck and bliss on!
