Hi! thanks for your prompt response. I appreciate it very much.
By the way, few minutes ago after I wrote the message, I tested the product on a hidden spot (bikini area) before I apply it on my face (to both corners of my upper lips). The result .. well, I am not sure I am happy with it because I notice the lotion seems just broke the hair not really pull of the root totally. I notice some black dots left behind although on some other area are smoothly clear. Will try again some other days and will leave it little bit longer (longer than 7 minutes), perhaps it would work better. Thanks again for the advice!
