Overly oily, dry, red or irritated skin may be signs your current routine isn't working explains Alster. Dullness, thick-feeling skin, larger-looking pores or pores filled with gunk are other signs your regimen isn't working points out Frankel.
"If you feel unhappy with your skin, then your routine isn't working," says Zilka. "You want to be using products that make you feel amazing — it's that simple."
You may also want to consider breaking up your routine. Use one serum in the morning and another in the evening. It's also important to allow enough time to see if a routine is working. Stick with it for at least a month before you judge.
