The idea of CELOUI Classic is to pack in all the needed ingredients and actives into one bottle. That way, we don't have to use too much preservatives and fragrances. Preservatives are a necessary evil. 😈 We need it but we should minimize the usage if we can. Take multi-step skincare routine (cleanser, toner, lotion, cream, mask, etc. you name it.) for example. Can you imagine how much preservatives and chemicals that will be stacked up through each and every step? 😱 The Celoui Cream and Essence minimized the usage of preservatives and fragrances while providing all the nutrients and actives your skin needs.
