Almost at the end of the bottle now, no point keeping it until next year, so it will be recycled and I shall now finish off my spf30. That's my routine, spf 30 during the spring months, spf 50 during the summer, and then back to spf 30 for autumn. I don't really bother much over winter, I know I should, but I don't go out much anyway, so I don't. Do you wear yours over the winter?
