If you’ve been wondering whether you should abandon your usual skincare products for those that are made of natural ingredients, this may be the proof of efficacy you’ve been waiting for.

L’Occitane is known for creating beauty products that are made of authentic and traceable natural ingredients, and one of the most popular in its offerings is the Reine Blanche collection. While it’s made of organic meadowsweet flowers, and none of the chemicals that other potent products contain, the Reine Blanche collection promises products that help to illuminate your skin and eliminate the appearance of pigmentation.

But don’t just hear it from us. See for yourself as we put its star product, the L’Occitane Reine Blanche Whitening Serum, to the test.

How does the experiment work?

Free radicals are the key culprits for causing dullness and pigmentation to appear on our skin, and the way to fight them is with strong antioxidants.

Iodine is a known strong oxidant. We drop some iodine (strong oxidant) into a glass of clear water (which represents your skin), creating a yellow-tinted mixture. Then, we add some L’Occitane Reine Blanche Whitening Serum into it. After stirring the serum in, we were shocked by what happens to the tinted mixture!

Watch our experiment to see for yourself!
