Yes. A gentle facial cleanser is the foundation of your entire routine. It cleanses your skin without drying it out and helps keep it calm.
A mild facial cleanser is always the first step in your routine, and honestly? It might just be the most important step. Throughout the day, all sorts of things accumulate on your skin: dirt, sweat, excess sebum, oil, and dead skin cells. A good cleanser removes all of that, but in a gentle way.
After cleansing, your skin should not feel tight or stripped. It should feel soft and comfortable. That's a sign that your cleanser is protecting your skin and not taking too much away. If your skin feels dry, red, or irritated after washing, that cleanser is probably too aggressive for you.
Also, take the time to cleanse properly. Quickly washing your face and moving on usually doesn't work. By gently massaging the product in, it can do its job. This prepares your skin for the products that follow and helps you get much more out of them. You can safely use a gentle cleanser both in the morning and in the evening.
