Readers have been steadily writing in asking about how to resolve your ingrown hair problem. Pesty post-waxing and shaving bumps look red, irritated and they can even itch a little bit. It's time you learn about Tend Skin Liquid.

This oldie but goodie has been a part of my life for years. I use it on my bikini line, and guys often use it on their face and on the back of the neck—essentially, wherever ingrown hairs usually form.

To use, dampen a cotton ball with Tend Skin and pat it onto the bumps you'd like to banish. You'll feel a little bit of a tingling sensation. That's okay; just wait about twenty to thirty seconds for it to dry and you're good to go for the day.

Now your bikini line will look beautiful for the duration of your beach days! Tend Skin is available in a four-ounce bottle ($20), an eight-ounce bottle ($35) and a 16-ounce bottle ($50). But if you're allergic to aspirin, take a pass: One of Tend Skin's main ingredients is acetylsalicylic acid, which is—you guessed it—aspirin.
