Wrinkles
Skin wrinkles are caused by a variety of factors. Some of these factors are intrinsic, meaning that you cannot control them because they occur naturally. Others are extrinsic, meaning that they are caused by circumstances outside of the body.
One intrinsic factor is aging. As you age, your skin loses collagen, which is the protein responsible for keeping your skin elastic. With less collagen, your skin becomes thinner and more fragile. Aging also reduces the functioning of sweat and oil glands, which work to keep the skin looking smooth. You also lose fat in the deeper layers of your skin as you age. This fat loss causes your skin to sag and develop deeper wrinkles.
The two most common extrinsic factors are exposure to ultraviolet radiation (UV rays) and smoking. UV rays in sunlight break down your skin's connective tissue and collagen fibers. To prevent the appearance of wrinkles (as well as protect yourself from skin cancer), you should always use UV-blocking sunscreen. The nicotine in cigarettes is the most likely link between smoking and wrinkles. Nicotine narrows the blood vessels, reducing the blood supply to your skin tissue. This deprives your skin of oxygen and important nutrients, causing damage that contributes to wrinkles.

Quizplus · Accepted Answer

In paragraph 2, it is stated that aging skin loses collagen. Therefore, this is the correct option.
It is still elastic when compared to younger skin is incorrect. In paragraph 2, it states that the skin loses collagen, which keeps skin elastic. Therefore, one can infer that skin that has gone through the aging process is not still elastic.
It has developed a thick texture is incorrect. In paragraph 2, it states that with less collagen, your skin becomes thinner. Since it is stated that aging skin loses collagen, one cannot infer that aging skin would develop a thick texture, but rather, a thin texture.
It will have a smooth and saggy appearance is incorrect. Although paragraph 2 states that aging skin will lose fat and cause the skin to sag, it does not mention that the skin will look smooth. Rather, it states in paragraph 2 that aging reduces the functioning of sweat and oil glands, which work to keep the skin smooth. Therefore, one cannot infer that aging skin will have a smooth appearance.
