When you have rosacea, there’s no question about whether or not you need a good moisturizer: Dr. Ilyas says moisturizing is an essential step since the product can serve as a barrier that protects your skin from the environment while it hydrates. That said, it can be hard to judge how often you should be moisturizing: You don’t want your skin to be overly oily and even more prone to breakouts, but dry skin isn’t ideal for your rosacea, either. “Moisturizing at least once a day is important,” says Dr. Ilyas, “and if you live in a cold, dry environment, considering moisturizer twice daily may help more.” You should also pay attention to how your skin responds to moisturizing once or twice per day; if once per day seems to keep your skin sufficiently hydrated and comfortable, stick with it. On the other hand, if you feel like your skin would benefit from more moisture, bump up your application to twice per day.
