Can your skin purge from 0.1% retinol?

I am one week into using 0.1% retinol at night, in sandwich method with a kojic acid cream recommended by my doctor and a ceramide gel moisturizer to seal. Before I started I had mild acne but 4-5 days in my skin is so inflamed and full of closed comedones surfacing as small zits and some deep and painful acne on both cheeks and forehead. Is this a retinol purge? Can you purge from such a small concentration? How long will it last?
