I learned the hard way how heat, even after a short period of time, will destroy skin products. The consistency becomes a runny mess and in that state it remains. I live in Houston, TX, where it is obviously very hot a good portion of the year, but summer heat is intense most places. For some reason our new mailman leaves packages on top of the large brick mailbox in the blazing sun. This time I ordered a product I added the thermal liner. I was nervous when it came because the outside box was so hot, but my moisturizer was room temperature. Yeah!

I'm so thankful I ordered the liner. The protection against breakage and severe weather was so well worth it! We've been experiencing below 0 weather. My products were perfect. Thank you

Got this for my order to protect my products during a heat wave

I ordered a seven-product bundle at the height of summer heat and was worried my Eminence goodies would be worse for the wear, so I added this liner for added protection. I was amazed how well it worked. All products arrived at room temperature despite being shipped and traveling in nearly 100 degree heat for three days. Definitely recommend purchasing this if buying products during the summer!

To me, this is worth the extra cost to be certain my products arrive at full strength rather than potentially weaker due to the heat. The thermal liner works well even in the hottest months of the year. I wish more companies offered this shipping option.
