[Acne] Why haven't I experienced flaking with Paula's Choice 1% retinol treatment?

Beauty Tips For Body Care
So a few months ago I bought PC's 1% clinical retinol treatment. I remember using it for a week and then stopping because I didn't see any change in my skin. Last week, I decided to give it another try. I know that a lot of people recommend not using it every night and to buffer it with a moisturizer when you first start using retinol because it can be irritating and make your skin red and flaky. But I've been using it almost every night for a week now. I apply one full sized pump on my face and neck immediately after cleansing and I don't even use moisturizer or anything on top of it. But for some reason, I haven't experienced any redness or flaking. My skin's moisture hasn't been compromised at all (throughout the day, I use moisturizer like usual but I don't use moisturizer with the retinol cream at night). I do notice that I've been getting a few more pimples (is this purging?) and that my lips are a bit dry (maybe i got some on my lip by accident)? But no redness or flaking. Even the few extra pimples I've gotten aren't that bad compared to other stories I've heard of people who first started using retinol. Is this normal? I'm just worried that I'm not doing something right or that the product I got is faulty. I want to make sure that the retinol is actually doing something to my face.
