I've been applying moisturizer on my face just before going to bed, along with Vaseline on my lips. I have no problem with doing that, but I do not know if I am using it at the wrong time of day. I read someone saying they apply it a few hours before going out, so maybe that is the right time. Maybe there is no 'wrong' time.
Not a huge health problem at all, but couldn't see a more appropriate part of the forum to stick this in. Thanks.
