Nanoparticles are ultra-tiny particles. So tiny in fact, they can measure 1,000 times smaller than the width of a human hair.
The use of Nanoparticles in skincare has become controversial for several reasons:
- Because of their small size, it’s generally accepted Nanoparticles can penetrate the skin (at least the upper layers).
- Some particles can accumulate to toxic levels (due to the small particle size).
- There are many unknowns. Little research has been conducted regarding the safety of Nanoparticles.
- If Nanoparticles don’t enter through the skin, there’s also the possibility they’re being unintentionally inhaled.
Some beauty products include Nanoparticles. In skincare, Nanoparticles are most often found in sunscreens, foundations and other makeup products. The main ingredients we’re referring to are metal oxides like zinc and titanium dioxide.
Broadly speaking, traditional sunscreens that contain zinc and titanium dioxide leave a chalky or white residue on the skin. Skincare manufacturers have turned to Nanoparticles as a solution to this cosmetic problem. Nanoparticles are able to deliver physical UVA/UVB protection without a chalky or white residue. However, consumer advocate groups report the vast majority of skincare brands using Nanoparticles don’t mention it on their labels. This leaves many consumers unable to make an informed decision.
Given the controversy and overall likelihood Nanoparticles can be absorbed by the body (in one way or another), all ExPürtise products are formulated Nanoparticles free. We believe skincare products should improve your skin, be as pure as possible and deliver a luxurious experience without any controversial ingredients.
