I read several threads on this forum about how to properly store specific products.
I ordered yesterday the full treatment from Dr. Pickart website, including Emu Oil S for Skin, LacSal Cream, Protect & Restore Classic Cream, Retinol in Squalane, Super GHK Copper Cream, Two Timing Tightener.
I read on a forum thread that hydroxy acids, such as LacSal, should not be placed in the refrigerator, is this correct? If so, are they ok even if the environment is warm (up to 80 deg)? My house gets extremely hot, as it is hit by the sun for the whole day, I live in South Cali and it's warm year around.
Other than hydroxy acids, are there any other products that should NOT be stored in the refrigerator?
Many thanks in advance!!

You can store most of the products in the refrigerator. We have Seattle weather so most products never become very warm.

If products are stored in a warm area, they still work but start smelling a little like Soy Sauce.

I see, so even Hydroxy Acids based creams such as LacSal is ok in the refrigerator?
