According to the search results, moisturizer should be applied before primer. It is recommended to wait for a few minutes (around one to five minutes) after applying moisturizer before applying primer to achieve the best results. Moisturizers are designed to hydrate and nourish the skin, while primers are designed to create a smooth surface for foundation. Applying primer first can lead to dry, lackluster skin. While there is flexibility in the application of certain products, this isnt the case for makeup primers and face moisturizers. Achieving long-lasting makeup and a flawless complexion requires getting the order right.
