Wow! Thanks for the instructions and concern? However, as for me, I believe I'll continue using it! I haven't experienced any problems nor have my friends using the same kind! I haven't seen an experation date nor have I heard of a recall on this product! I understand mary kay may have changed samples or formulas since this particular one but hat doesn't mean its bad for your face! Definatly no immedicate bad results! My face is fine, healthy actually after using this product for months! I believe its possible for a select few to have adverse reactons as do certain people with any line of cosmetics or a specific item from the line! However, you can't let one bad egg spoil the bunch! Last but not least...I use this product myself and I would never auction off something I knew to be bad, or something I wouldn't use myself!
