I don't use an extra moisturiser after applying the LG. They always say during the presentation that the LG is best if used alone, but you can use a moisturiser afterwards (that's written on the bottle, to put a moisturiser on top when the skin is touch-dry).
Thanks, Ani (or Me Minus D, as I think of you). I think I'll carry on with using a dab of cream occasionally only. I think my skin likes LD on the whole.
