To all of you who have been complaining about the NO STOCK issue... It has been taken care of. We have almost 50 lip colors and all are in stock! The reason behind that issue was that the company was not prepared fop the takeoff of the product. The reason there is a burn when applying the lip color is this. It burns because of the cosmetic grade alcohol that is used to sterilize the product when you dip the wand into the tube which also will kill any bacteria you may have on your lips when applying. The first time you try LipSense it can tingle. This is because the lips are dry and not sufficiently moisturized. Those without dry lips do not notice this. The sensation will stop once you have finished the application and applied the moisturizing gloss. After you have used the Gloss for a day or two you will rarely ever experience the tingling again. Dry lips can be caused by repeated use of wax and paraffin based lipsticks, which, by their nature, can cause dry lip tissue. You can eliminate this by conditioning the lips for a few days and not using any wax based products. Once you use the LIPSENSE and the Moisturizing Gloss on a regular basis the dry lips will be gone forever. I myself have been using LIPSENSE for months and the only time i experience the "tinge, burn" is if I have gone several days and not used the gloss or lip balm.
