Hello,

I would like to know why they're NO expiration dates on your products ???

THANKS VERY MUCH

Dear lila:

Well, we've tested product up to 5 years old (kept at normal room temp) and the efficacy was the same.

Certain products (like Emu Oil-S) will not keep nearly as long of course. But the products do seem to keep well for quite some time.

Best Wishes,

OK, Thanks

Is this also true of EXOFUL SERUM ??

I still haven't started to use mine yet, cause I've been using the SUPER CP SERUM and now CP Serum and Emu oil trying to improve some marks that
I recently had needling on ... Therefore, I wanna make sure that the EXFOL SERUM has a long shelf life as well ... I purchasd it last February.

Thanks a bunch !!!

Dear lila:

Exfol Serum does seem to last a while (not as long as SRCPs). I don't think we have a certain time period associated with the use of this product.

Look for any drastic discoloration of the color of the serum, consistency, or smell.

Hmmmm ... I really do NOT understand the REASONING behind the "NO EXPIRY DATES" to be honest ...
I never did like guessing games ... I would much prefer NOT to have to worry and/or GUESS ... Is the product still ok ... should I keep using it ?? throw it out ?? etc ... sigh ... Regards

Our products are more like foods that the usual petrochemical-based skin products.

We put the manufacture date on the product.

If you keep milk cool it last a long time. In heat it decays. Our products are somewhat similar.

Oh ok ...

I was wondering ... since it's been so humid lately ...

Would u suggest that I store the products in the fridge (CP Serum, Super CP Serum, Exfol)??
Right now they're in a closet in my bedroom where it is somewhat a little less humid than the bathroom or kitched cabinet :-)

Thanks Dr. Pickart

Just keep them on the cool side. We are near Seattle and it is always cool and products last for at least two years. You can refrigerate them if you wish.

I stored my Exfol Serum and CP Serum in my bathroom with a shower (w/ humidity changes but constant indoor temperature). The samples I had were still bioactive after 3.5 years.

ok ... Thanks again
