We have been using the SilkBalance system since we first started our Spa. My wife says her skin is softer and I have to agree with her. First let me say how pleased we are with you product. We are new to the Spa world and after purchasing our spa my wife had some concerns about her skin. We spoke to our dealer and she suggested the SilkBalance system and are we glade she did. Thank you for formulating this product, we hope to be Silk Balance users for years to come. Sincerely Frank Pellegrini
