Should you’ve ever ordered a product from Renée Rouleau Pores and skin Care, know that it was shipped straight from our headquarters in Austin, Texas. If there’s one factor it is best to learn about Texas, it’s that it will get HOT in the summertime (and within the fall, too). The truth is, it’s not unusual for the temperature to succeed in triple digits. That signifies that the field we’re transport might sit in a sizzling mail truck for hours. Relying on the place you reside, it could sit on a sizzling doorstep, too.
So, what does that imply for you? Does warmth have an effect on skincare merchandise? If that’s the case, will a scorching summer time day spoil your favourite components? On this publish, I’ll share the reply to this widespread query.
Does Warmth Have an effect on Skincare Merchandise?
As somebody with over 30 years of expertise working as an esthetician and product formulator, I can confidently say that the reply isn’t any. If a product has been formulated correctly, warmth mustn’t have an effect on its efficiency. Let me clarify why.
Most Skincare Merchandise Are Examined with Warmth Publicity
When skincare merchandise are made in an authorized laboratory, chemists will do stability testing. This contains an “oven take a look at.” Throughout this take a look at, a product is positioned in an oven with a temperature of round 115°F at 70% humidity. The product is stored in there anyplace from six weeks to a few months. The aim is to find out whether or not a product can keep stability and integrity when uncovered to excessive warmth.
It additionally helps decide the shelf lifetime of a product by artificially growing old it, making a “time-lapse.” It tells us if a product will stay steady for a full two years and whether or not or not it’s regular for a components to separate or change consistency over time. Conversely, merchandise are additionally subjected to chilly temperatures throughout stability testing to see if they will maintain as much as freezing temperatures.
All Renée Rouleau Pores and skin Care merchandise undergo this stability testing. They’re uncovered to warmth over lengthy intervals of time to make sure security, efficiency, and longevity. So, relaxation assured that in case your skincare merchandise get sizzling, they received’t spoil or lose efficacy.
Observe: The oven take a look at doesn’t think about UV mild. If a product is uncovered to UV mild for a very long time, and it’s housed in clear packaging, it can probably lose efficacy. It’s because components like antioxidants and UV filters (in sunscreen) have a tendency to interrupt down within the presence of sunshine. I like to recommend storing your merchandise in a closed beauty bag and maintaining them out of direct daylight.
I additionally advocate buying merchandise which are housed in airless containers since oxygen can degrade sure lively components. All Renée Rouleau Pores and skin Care serums are packaged with airless pumps to maintain the components contemporary and efficient till the final drop!
Not All Skincare Merchandise Are Made the Similar Method
Whereas it’s true that the majority merchandise which are made in a lab are held to rigorous requirements, there are some skincare merchandise that merely aren’t made to stay steady in warmth. These embody “all-natural” merchandise, small-batch merchandise that are supposed to be refrigerated and used shortly, and home made merchandise like these you would possibly discover on Etsy.

You additionally would possibly need to take into account inquiring about this earlier than you make a purchase order. In spite of everything, I can solely communicate for my merchandise, which received’t lose efficacy in sizzling temperatures.
