I tried checkcosmetic.net but unfortunately it doesn't let you choose Decleor, Gatineau or Elemis. Odd - I'd have thought the more reputable brands would be happy to be there.
Hi thatu, here's how to identify the date of manufacture (DoM) of Elemis items. I have used a PCMC from Dec 12 TSV and the PC Cleansing Balm from May 13 TSV
PCMC 023
0922A 09 = September and 22 - 10 = 12 = 2012
Cleansing balm last four digits = 0323, therefore DoM is March 2013
With regard to Decleor, it is a little more difficult. I concentrate only on the year of DoM.
If the product code starts with a T, assume 2010; U = 2011; V = 2012.
I contacted Elemis, and was given the information. Decleor declined. In consequence, they lost my custom. If I really need something from Decleor, I check the product code before buying. I have not asked Gatineau, although I am still awaiting a reply from Gatineau to my request for information of MI.
I do have fairly sensitive skin, so I try to be careful about product ingredients and DoM. If a cosmetics company is not willing to be open, then I go elsewhere. I like Elemis products, and have been using them for years, and I find the company very open to requests for information. Should this ever change, I shall be off! Jay
