Ingredients are the most important component of a product, and Chelsea is always proud to showcase them. Ingredients are not selected based on their aesthetic value - only formulations with ingredients that are truly beneficial to the skin are chosen. Chelsea selects a wide range of natural ingredients and uses a minimum of preservatives in its formulations, enough to give its products a shelf life.
