I don't know that Hirons' face is damaged from the sun, so much as normal aging (which comes from within your skin, based on your genetics - although she is the advert that nothing you put on your skin will do anything about that), plus too much botox which always seems to result in wrinkly eyes, I assume because the tiny muscles are overworked trying to compensate for the bigger muscles which have been nuked with botox. Plus there's nothing that can really be done about the neck because it needs to move.
I'd say there's a lot going on behind the scenes with injectables and lasers which she omits to mention, because it won't help her flog product.
