  1. Once upon a time 20 was considered sunblock. I never understood needing higher numbers.
    Another factor is the base material. Like oil vs cream. Knowing that cream gets in your skin and loses it
    it’s efficacy within a year in the bottle/tube, and oil stays on your skin, and doesn’t lose it’s properties so fast, for one they can have a transparant bottle because light doesn’t degrade it, contrary to creams. Seems an important factor to me considering it’s function.

  2. The real question is how much do you have to use to get all the benefits, because I guarantee it’s a lot more than most people use.
