It is different because it is a thick wax and does not penetrate the skin. It creates a hard layer over the skin to hold in the moisture (and moisturizers) in the skin. The heat opens the pores to allow that moisture to penetrate better. The liquid form of parafin is mineral oil which is not good for the skin when used in products as a moisturizer.
Here is an explanation I found on line..."The paraffin itself does not enter the skin because the molecules are too large. It is my understanding that the paraffin heat causes increased circulation and opened pores and the paraffin itself creates a barrier and encourages the body's own moisture to be re-absorbed by the superficial layers of the skin, and enhances absorption of any lotions or creams applied to the skin before the paraffin application."
Sadly, some Asian nail salons (but certainly not all) are operated illegally without the proper licenses (or fake ones) and they don't always take sanitation very seriously, so I have heard of people getting nail infections from some shops. There are very few state inspectors to check on all the shops that are out there so they don't get caught very often, unfortunately. That is not to say that non-Asian shops are exempt from the same unethical and unsanitary practices. You just need to get recommendations from people you know who have been to a good shop.
