I found the article very interesting, as I have never heard this claim before. I was raised in a household where we were taught to wash our face morning and night, so it never occurred to me that there might be some skin types that benefit from only washing once a day. However, I feel that it is important to point out that the original "source" of this claim is a Vogue article, which brings me to question its validity. Vogue's publishing efforts are not really oriented towards health and wellness, instead beauty and lifestyle. So I do not think it is wise to follow Vogues words as the end-all-be-all of dermatology. The article provided also fails to include the fact that every single individual has a different skin type, and their skin can handle extremely different things. I, personally, have very sensitive skin that breaks out if I fail to use the same set of products, or don't wash my face twice a day. On the other hand, I have friends that can go days without washing their face and have perfectly clear skin. Therefore, there is no distinct answer that yes, it is better not to wash your face in the morning, as it all depends on the nature and sensitivity of one's skin.
