FAQ

DECIEM does not test on animals and does not ask others to do so. DECIEM has been certified with the Leaping Bunny stamp of approval, a widely recognized standard for personal care and household products.

The Ordinary, The Chemistry Brand, and HIF have been certified vegan by PETA, and we are currently obtaining certification for all other DECIEM brands. Until then, please refer to our legend for each product on our website that will indicate the specifications of any given product (for example, if it is vegan, nut-free, oil-free, etc.)

We know there's nothing worse than waiting! We recommend signing up for our email notifications for products that are out of stock. If you click the "Email Me When in Stock" button underneath the product you're interested in, we'll let you know as soon as it's restocked!

Kindly note that these notifications may be unavailable during promotional periods. However, please check back regularly as we will be restocking on an on-going basis as normal. Please also note that our team is not able to provide restock estimates for products that are unavailable. We apologize for any inconvenience!

Some products like those containing Granactive Retinoid or the UV Filters SPF 45 Serum are not available due to local restrictions. However, we do have alternatives in our Retinoids.

Unfortunately, we do not offer product samples at this time! We encourage you to visit one of our DECIEM brick-and-mortar stores to test our products in person.

We recommend storing our products in a cool dry place away from direct sunlight. Some products such as The Ordinary Granactive Retinoids/Retinols do require refrigeration after opening, but this is noted on the directions.

For all others we suggest storing at room temperature, however, there is no harm in refrigerating (with few exceptions).

A few products such as NIOD CAIL 1% and our sun protection products will have an expiry date noted on the packaging.

For all others, the shelf life is three years when unopened and stored at room temperature. This is the regulatory threshold for testing. Upon opening, please refer to the period-after-opening (PAO) symbol to identify the lifetime of the product.

While each ingredient has been tested and is considered safe for topical application, DECIEM products have not been tested on pregnant or breastfeeding people. When pregnant or breastfeeding, it is recommended to avoid any skincare products containing retinoids such as formulations with Granactive Retinoid or Retinol.

Patch tests are an easy way to help predict if you will have a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating a new product into your routine. We have outlined a general method for conducting your own patch test based on the type of product.

The safety of our customers is a key priority, which is why we are committed to the prevention of the sale and distribution of counterfeit products or products sold through unauthorized retail channels.

Unfortunately, we are unable to verify the authenticity or integrity of any products or packaging that have not been purchased directly from DECIEM or one of our authorized retailers. For your safety and to achieve the intended benefits of our products and technologies, we strongly recommend only purchasing from authorized retailers or us directly.
