A brief YouTube short by dermatologist Shereene Idriss explaining that moisturizing depends on both skin type and environment.

You guys have been moisturizing all wrong. I'm a 39 year old board certified dermatologist. Yes you need to moisturize based on your skin type but the one thing that people do not take into account is your environment because a dry person in a dry climate is not the same as a dry person in a humid climate. Your skin is a living organ. It changes based on its environment. Think of this as a pyramid. Right at the top of the pyramid we have the ones who won the jackpot even though they do not know it. The oily ones in a humid environment. Why? Because you my friend do not need to moisturize. All you need to do is use sunscreen. Second, oily and dry. Although you may think you do not need to moisturize as much, you should moisturize a little bit. Make sure your moisturizer works for you with active. So let it be a two in one whammy. Maybe something like a gel moisturizer with vitamin C.
