Heineman Shlit”a they have a viscosity of 600 cP or less, Aside from this if the cream or lotion is being done to get rid of dry skin etc. it will also have an issue of refuah on Shabbos. It would be advisable to put on a nice layer of it right before shabbos so it can last as long as possible, or get a kind that is long lasting if possible.
