Why not glass?

Recycled plastic represents a more environmentally friendly choice than glass for this product, in part due to its lighter weight and how that impacts transportation.

Additionally, plastic was chosen for safety reasons due to the risk of breakage associated with glass, especially in potentially slippery spaces such as showers and baths.

Why a refillable plastic bottle? Why offer an empty plastic bottle?

It is not necessary to purchase the refillable bottle. You can buy the eco-refill by itself and transfer it into a reusable bottle of your choice or that you already own. However, if you do not have a suitable bottle, Yves Rocher supports you in adopting a more sustainable shower routine by offering a refillable bottle made of 77% OBP recycled plastic sourced from coastal areas and equipped with a practical pump that helps to control the quantity of product used.
