Clinical Formulations
with Integrity.


  1. How do I use multiple formulas in a regimen?
    In general, water formulations should be applied before oil formulations and we recommend using a maximum of three serum formulations in a single regimen. We have developed a more comprehensive guide on choosing and using our formulations. Please click here to access this guide.
  2. Do you offer a refund policy?
    Yes, we offer a 365-day full refund policy across all DECIEM brands including The Ordinary.
  3. What is your policy on animal testing?
    DECIEM and The Ordinary do not test on animals and do not ask others to do so. For this reason, none of our brands or products are sold in mainland China since such sales require animal testing for registration purposes.

  8. Why do you offer so many different formulations with Vitamin C?
    Topical Vitamin C offers a wide array of benefits to the skin. However, many forms of Vitamin C and many more formulations of Vitamin C are available commercially with a potential to confuse the audience. We have developed a guide that offers guidance on the formulations of Vitamin C offered under The Ordinary range. It also offers education on Vitamin C itself and on the differences between formulations of Vitamin C at large. Please click here for this guide.

    All DECIEM products, across all brands including The Ordinary, are free of parabens, sulphates, mineral oil, methylchloroisothiazolinone, methylisothiazolinone, animal oils, benzalkonium chloride, coal tar dyes, formaldehyde, mercury, oxybenzone.
