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 you must find out about Texas, it’s that it will get HOT in the summertime (and within the fall, too). Actually, it’s not unusual for the temperature to achieve triple digits. That signifies that the field we’re delivery 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? In that case, will a scorching summer time day spoil your favourite components? On this publish, I’ll share the reply to this frequent 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 shouldn’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 consists of an “oven check.” Throughout this check, a product is positioned in an oven with a temperature of round 115°F at 70% humidity. The product is saved in there wherever from six weeks to 3 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 older it, making a “time-lapse.” It tells us if a product will stay secure 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’ll 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 durations of time to make sure security, efficiency, and longevity. So, relaxation assured that in case your skincare merchandise get sizzling, they gained’t spoil or lose efficacy.
Word: The oven check doesn’t think about UV gentle. If a product is uncovered to UV gentle for a very long time, and it’s housed in clear packaging, it should most definitely lose efficacy. It is because substances 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 preserving them out of direct daylight.
I additionally suggest buying merchandise which might be housed in airless containers since oxygen can degrade sure energetic substances. All Renée Rouleau Pores and skin Care serums are packaged with airless pumps to maintain the substances contemporary and efficient till the final drop!
Not All Skincare Merchandise Are Made the Identical Method
Whereas it’s true that almost all merchandise which might be made in a lab are held to rigorous requirements, there are some skincare merchandise that merely aren’t made to stay secure in warmth. These embrace “all-natural” merchandise, small-batch merchandise that are supposed to be refrigerated and used rapidly, and home made merchandise like these you may discover on Etsy.
On the finish of the day, there’s no assure {that a} product has undergone rigorous testing for excessive temperatures. Preserve this in thoughts whenever you’re searching for skincare merchandise. You additionally may need to take into account inquiring about this earlier than you make a purchase order. In any case, I can solely communicate for my merchandise, which gained’t lose efficacy in sizzling temperatures.
Subsequent, discover ways to inform whether or not or not a skincare product has expired.
