I'm trying Ole Henriksen right now for the first time! I'd heard it was harsh too but so far it's totally fine and not harsh at all.
I'm using the "Truth is in the Eyes" serum, which is supposed to be a gentle under-eye peel, which you leave on overnight. It tingles but not unpleasantly so; though the smell isn't great.
I am also trying out the Invigorating Night Gel from a sample. IT also had reviews for being harsh, but it hasn't affected me badly in any way, and doesn't sting or anything. Supposedly it shrinks/clears pores. It does feel a bit tight and requires a moisturizer in addition- but already my skin feels smooth and soft!
I want to try: the Visual Truth Eye Cream, and the Pure Perfection face. Anyone have any experience with either of those?
