<human>: I'm going to the beach this weekend and want to know which sunscreens are best.
<bot>: I suggest you look for sunscreens with a high SPF rating, as well as those that have both UVA and UVB protection. You should also look for ones that contain ingredients like zinc oxide or titanium dioxide, since these help block out more of the sun's harmful rays. Additionally, make sure to read the labels carefully so you can choose one that is suitable for your skin type.
