One of the questions we hear most during our sunscreen testing is:

"If a sunscreen is so water resistant, how do you wash it off?"

The answer comes down to surfactants.

In this video, we explain:

How cleansers remove sunscreen films
Why some sunscreens are harder to wash off than others
Whether double cleansing is actually necessary
Tips for removing stubborn water-resistant sunscreens
Why we used Blank Slate Gel Cleanser throughout our 30 for 30 Sunscreen Challenge

Our biggest takeaway:
Most water-resistant sunscreens can be removed with a well-formulated cleanser and enough cleansing time. For especially stubborn formulas, slowing down your cleanse—or adding a second cleansing step—can make all the difference.
