Short answer: it should be adapted to your skin type.
The best skincare routine for you is the one that encompasses all the basic steps of cleansing, toning, and moisturizing. But it should also be tailored to your specific skin type. For example, those with dry skin will need a heavier moisturizer than someone with oily skin. And someone with sensitive skin might need a gentler cleanser. The bottom line is that there is no single skincare routine that works for everyone.

That said, there are some general tips that can help anyone achieve optimal results. First, always cleanse your face both morning and night to remove dirt, oil, and makeup. A good cleanser will leave your skin feeling refreshed and ready for the next steps in your routine.
