防晒霜英语怎么写

How to write sunscreen in English and what does it mean? Here are at least four aspects to introduce:

1. Definition: Sunscreen refers to a product that is applied topically to protect the skin from the harmful effects of the sun's UV rays. It is designed to prevent sunburn, premature aging, and skin cancer caused by exposure to the sun.

2. Composition: Sunscreen is typically made up of a combination of active ingredients that work to absorb, reflect, or ter UV radiation. Examples of these ingredients include zinc oxide, titanium dioxide, and avobenzone. Other ingredients like emollients and humectants help to keep the skin hydrated while providing a smooth and even application.

3. Types: There are two main types of sunscreen: physical and chemical. Physical sunscreens work by physically blocking UV radiation from penetrating the skin, while chemical sunscreens work by absorbing UV radiation before it can cause damage. Some sunscreens may also be water-resistant or sweat-resistant to provide longer-lasting protection.

4. Importance: Using sunscreen regularly is important for maintaining healthy skin and preventing skin damage. Overexposure to UV radiation can lead to premature aging, sunburn, and an increased risk of skin cancer. Sunscreen can help protect the skin from these harmful effects and should be worn daily, especially when spending time outdoors.
