Skincare routines with:
The Ordinary Soothing & Barrier Support Serum

Use your azelaic acid product every other day, either in the morning before your sunscreen or at night, before your moisturizer.

Start slowly with this product: it can be irritating, but your skin can adjust to it with time. It is best to start using this product only once a week for the first few weeks. Mild dryness is normal when starting using a retinoid. Once your skin is able to tolerate the product well, you can increase the frequency of use to twice, and even three times a week. Make sure to apply a moisturizer regularly when using this product. Apply this product on clean skin, before a moisturizer. Most people prefer using this product at night, but it can be used in the morning as well.

Use a generous amount of product to remove all dirt, sunscreen or makeup in one step. There is no need to double-cleanse. It is a good idea to always finish cleansing with a splash of clean water to remove any residue from the cleanser. Most people only need to cleanse their skin with a cleanser once per day, at night. It is the first step of a night skincare routine.
