What is a sunscreen stick?

Sunscreen sticks are stick-shaped sunscreen creams. They are a little sticky when applied, but they will get better after a while. They are also easy to carry and you don’t have to worry about security checks.

This chemical-free sunscreen stick is formulated with Nano-UV filters to scatter and reflect harmful UV rays, providing highly effective UVA-UVB broad-spectrum sun protection. The non-staining formula is easy to apply and can be used in conjunction with SPF30+ sunscreen.

Is the sunscreen stick waterproof?

Most of the sunscreen sticks on the market are waterproof to a certain extent. Although compared with some sunscreens that are mainly used outdoors, the waterproofness of sunscreen sticks may be slightly worse, but there is no problem with general sweating, as long as you don't go into the water, the sunscreen sticks can meet the requirements.

It is recommended to use up the sunscreen stick within the same year after opening it, because the sunscreen stick usually needs to be rotated to a certain height of the paste during use, so the paste will often come into contact with the air and may even be contaminated with bacteria that are invisible to the naked eye during use. Sunscreen sticks are recycled, so the effective ingredients in them will definitely be affected. Therefore, it is recommended that the sunscreen stick should be used up within the same year after opening, and not saved for use next year.

Okay, now you know what a sunscreen stick is.
