Take the Lips Quiz
Lips are for...talking and kissing and eating. Yes, they're important, but do you know how to take good care of your lips? Take this quiz to find out.
1. Your lips are part of the top layer of your skin (epidermis). But why do you need to treat them differently from the rest of your epidermis?
You didn't answer this question.
You answered
The correct answer is
Unlike the rest of your skin, your lips have an extremely thin outer layer. This lets moisture evaporate more quickly. Your lips also have none or just a little melanin. Melanin is the natural pigment that screens out the sun. Lips also have few sebaceous glands and make little natural oil. And finally, lips are almost always exposed to the elements.
2. What is the best way to protect your lips from the sun's damaging rays?
You didn't answer this question.
You answered
The correct answer is
Lipstick and lip gloss do provide some protection. But they can't give you the same protection as a product made with an SPF rating. Don't lick your lips, because saliva acts like a lens and makes the sun exposure stronger.
3. Other than skin cancer, what effects can sun overexposure have on lips?
You didn't answer this question.
You answered
The correct answer is
Collagen gives lips body and resilience. It can be altered over time. Fine lines and wrinkles can develop as well. Prevention is the best defense to keep your lips healthy. That's because it can take years to see the effects of overexposure. Sun exposure can actually trigger an outbreak of cold sores, not clear them up. Lips will not tan, because they have little or no melanin.
4. When is sun protection for your lips important?
You didn't answer this question.
You answered
The correct answer is
It's important to protect your lips from the sun at all times. The level of UVB rays—those that contribute most to skin cancer—is greater in warmer months. But the level of harmful UVA rays throughout the year is fairly constant. Clouds don't protect you from UVB rays. Snow reflects the sun's rays, which increases your risk for sunburn.
5. Chapped lips aren't the only problem that can occur from neglected lips. What other conditions can occur?
You didn't answer this question.
You answered
The correct answer is
Over time, too much sun exposure can cause skin cancer to develop. Sun exposure can also trigger cold sores or cheilitis. Cheilitis is an inflammation of the lips.
6. Which of the following can cause lip irritation?
You didn't answer this question.
You answered
The correct answer is
Sensitivities or true allergies to certain types of food, makeup, or cigarette smoke can develop at any time. Wearing lip balm can't prevent an allergic reaction. But dry lips are more likely to get irritated.
7. As you age, what does not happen to your lips?
You didn't answer this question.
You answered
The correct answer is
Lips need more moisturizing and conditioning as you age. The outer layer of skin thins even more, and natural hydration decreases.
