am I missing anything from my skincare routine?

[Looksmaxxinggawhd]

My routine usually goes like this, salicylic acid oil free face wash, exfoliate twice per week, Vitamin C serum after exfoliate, moisturizer and 2.5% benzoyl peroxide spot treatment and also a clay mask once or twice per week.

is this an effective routine? and is there anything I can add to it that would make it more effective
