I'm looking for advice on daily skin care.

Recently, I've been looking in the mirror before an important interview, and I'm really worried because my skin looks particularly rough and my complexion looks dull. Until now, I've just washed my face and dried it roughly, but now I've decided to really start taking care of my skin. My friends are already using eye cream, so I'm starting to get anxious, wondering if I'm just behind. Are there any simple skincare routines that even beginners like me can follow at home? If you have any, please share them. Healthy skincare that I can incorporate into my daily routine, rather than expensive procedures, would be incredibly helpful. Sharing your tips would be incredibly helpful. I'd also like to hear your advice on the order in which you typically apply your cosmetics after washing your face.
