I'm a nurse, but I have degrees in several branches and science and in the fine arts (learning is an obsession ....)

Parasol 1789, widely promoted in the 90's is very unstable.

I'm pretty much a noctornal person, I even go to the beach at night. My sunscreen choices are clear zinc, lots of clothing, and some of the most stable sunscreens I can find by Blue Lizard.

I used to use sunscreen religiously every few hours when I went on day hiking trips, etcs.

I do recommend that if you are out in the sun to consider a generous base of mineral makeup like BE. It's sweat proof. On the neck and body, I'd get a zinc based cream. If you look at older people who live in tropical areas who don't sun themselves, but just live, shop, drive,etc, you will notice heavier pigmentation on the chest area,freckles on the arms,shoulders, neck, back,face, and hands. The skin on the belly-not so much. Melanin will concentrate in areas given constant exposure. You may notice some older women with "perma-tan" cleavages........this is sundamage. Recently I saw a 97 year old Japanese woman who never, ever leaves her home and she had pale, unmarked, and unlined skin. There was loss of elasticity, there was herniated sacs of fat under the eyes, but the pigmentation was that of a young child. She also had osteoporosis (sunshine gives us vitamin D, strengthens the bones).

When I was a child, everyone used baby oil. We thought the sun was good for you. In the winter we had ultra violet lights in the bathroom to "dry up colds, help with arthritis, clear up the skin". In the late seventies we got sunscreen, but it wasn't very good.
The most important weopon in your arsenal is common sense. Some sun exposure is vital. Laying out and baking is foolish. 45 min of volleyball in a bikini every so often won't hurt you, but if you are on the Rainbow Warriors Volleyball team-you need to have a good skin protection strategy .
Skin damage is cumulative. The body forgives some sundamage, but repeated insults can scar for life-subcutaneously.
