No, not what you hang the washing up with but Polyethelene Glycol –which can either be naturally derived or sourced from environmentally unfriendly mineral oil. In skincare, it is highly beneficial for your products to be penetrated beneath its surface so that it can work to its full potential. However, it needs something to give it a boost, which is where PEGs come in. They work behind the scenes to enhance the penetration of products - so, if you use a regenerating cream, PEGs are the clever things that help all the goodness from the product reach underneath the skin, for better results. But what if there isn’t any goodness in the product, or furthermore, what if it contains ingredients that aren’t skin-friendly? Regardless, the PEGs continue to carry them into the deeper layers of the skin, and it is negatively impacted as a result. So, in the name of not taking risks, we say no to PEGs just in case.
