If you’re savvy about skin care, then you’re definitely soaking your face in broad-spectrum sunscreen. After all, it’s the queen of anti-aging products.

But how diligent are you about protecting other exposed areas of your skin?

Cosmetic surgeons will tell you that your earlobes, backs of hands, neck, and chest will get their fair share of sun damage.

A small study found that people also often miss their eyelids (including the corners of their eyes) and nose bridge.

So, if anti-aging is your goal, don’t neglect these telltale areas either.

The 30-second beauty routine

Don’t be stingy with your SPF. Indulge the joy of squeezing out more than you need, just like you always wanted to do as a kid. (Most people only apply a quarter to a half of the amount of sunscreen they should be using!)

  1. Instead of rationing your supply, squeeze more than you think you need.
  2. Apply it to your face as part of your morning routine, and keep going down, down, and down until you’ve covered your chest and neck.
  3. To avoid tugging at your face, use the back of your hands to pat your sunscreen in. This way, you’ll be covering your hands too!
  4. If you feel you’ve run out, have another go at the bottle and revisit those places you passed over last (according to this study, people miss about 3.5 percent of the face), and give your earlobes a little protection too.

Sunscreen protects your skin from ultraviolet (UV) light, but the SPF in your makeup won’t cut it. While you might not see sun damage immediately, prevention is better and cheaper than treating the damage later.

To really protect yourself against skin cancer and the many other common signs of aged skin caused by the sun (like wrinkles and sunspots, coarse texture, and sagging), liberally apply that SPF.
