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 method? 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 is not 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

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 saved in there anyplace 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.

In spite of everything, I can solely converse for my merchandise, which gained’t lose efficacy in scorching temperatures.
