For everyday use, a face mask is more practical and sufficient for protecting against respiratory droplets and particles in the air.

It typically takes me about 2-3 weeks to use up 200ml of body lotion, depending on how frequently I apply it and the size of the area I cover. If I use the lotion daily on my entire body, it may last closer to 2 weeks. However, if I only use it on specific areas or every other day, it could last closer to 3 weeks. **

A 200ml sunscreen with SPF 30 may not be enough for a week-long beach vacation, especially if it is being used by multiple people. The amount of sunscreen needed for a week will depend on factors such as the frequency of application, the number of people using it, and the intensity of sun exposure. It is recommended to use about 30ml (or about an ounce) of sunscreen for the entire body for each application, and to reapply every 2 hours or after swimming or sweating. It's important to consider these factors and potentially bring additional sunscreen to ensure adequate protection for a week-long beach vacation. **

I prefer a sheet mask because it is less messy and easier to apply. Sheet masks also tend to stay in place better, allowing me to move around while wearing it.

While medical masks are also effective in reducing the transmission of the virus, the FFP2 mask is considered to offer a higher level of filtration and protection, especially in high-risk settings like public transportation. **

To find out how much mg of active ingredient 5ml contain, we can use the ratio of active ingredient to volume. First, we calculate the ratio of active ingredient to volume in 1ml: 125mg/200ml = 0.625mg/ml. Then, we can find out how much active ingredient is in 5ml by multiplying the ratio by 5: 0.625mg/ml * 5ml = 3.125mg. Therefore, 5ml contains 3.125mg of active ingredient. **
