i m not entirely sure still [SEP] the instructions are clear i watched a couple videos previously before receiving this on how it s done the bottles seem super pasty even after shaking longer than said to and i had to contact the seller about how to open the exfoliate and other bottle to which they said just break it openyou get what you pay for and for me like other reviewers it wasn t even a full day of color now i went into this blind as i ve never used a micro needle before too so maybe it was on me but definitely follow the part of no spicy foods for the next x amount of days
