The simplest strategies seems to just be wearing a baseball cap, or some sort of Mexican poncho hat, a wide brim hat, maybe even a Vietnamese style cone hat to protect you from the sun.
Also if you’re gonna go to the beach all day, to prevent yourself from getting sunburnt, maybe wearing a full bodysuit, some sort of full body wetsuit or something that covers up your shoulders neck etc. is a good idea
I’m actually anti-sunscreen; perhaps the potential chemicals and bad things in it outweighs the potential upsides.
Also, the whole sunscreen suncare, skin care, lotion sunscreen industry seems like a scam. Very very profitable, and thrives on fear marketing?
