While summer may be slowly coming to a close, there are still more than a few fabulous beach days left. However, while many women may think they have a foolproof skincare system for sun protection, some ladies may be making a few mistakes that can damage their skin.

Don’t be stingy when applying sunscreen, Dr Linda Evans told TotalBeauty.com. To make sure you are putting on the appropriate amount, Evans recommends using pocket change as a guide – apply a nickel-sized dollop for your face, a nickel for each arm, a quarter for your torso, a quarter for your back and two quarters for your lower extremities.

“People often forget [to protect their] lips and therefore lip cancer is on rise,” Dr Debra Jailman told the news source. Women can use a colorless lip treatment that boasts ample sun protection, like B. Kamins Chemist Lip Balm SPF 20, but those who want to add a bit of color can do so with kaplanMD Lip 20 Moisture Therapy + SPF, a lip balm which includes SPF 20 and comes in a variety of shades.

Depending upon your skin tone, sunscreen should be reapplied throughout the day. Evans recommends that fair-skinned ladies should reapply every two hours, once every three to four hours for those with olive complexions and darker-skinned girls should apply up to three times a day.
