So I have arranged for a therapist to come to the house to do a facial and massage as a treat. She was recommended by a friend. I’ve paid my deposit and really look forward to it. However/ I’ve just checked her website and noticed the products she uses are ‘all natural’ and I don’t think they will suit my skin (have to use prescription based skin care to prevent adult acne) would I be unreasonable to ask her to use my own products that I know suit my skin?
