Does sunscreen stop tanning?

Yes, sunscreen does stop tanning, at least to some extent. It does this by blocking ultraviolet (UV) radiation from reaching the skin. This is why it’s important to use sunscreen when you’re spending lots of time in the sun, as it can help protect you from skin cancer and other problems associated with too much UV exposure. However, sunscreen won’t completely prevent you from tanning, as some UV rays will still reach your skin; this can occur due to the sunscreen washing away or being wiped away, not enough being applied to begin with, or it not being applied properly. It’s important to remember that even if you are able to tan while wearing sunscreen, it’s still not safe to spend long periods of time in the sun without protection.
