Why Am I Still Red Three Weeks After Lux 1540? Is This Normal For Asian Skin?

I am 23 with Asian skin. I took Lux 1540 on November 30 on my cheeks and I am still fairly red. It is much redder after I use my glycolic cleanser, but even after it's calmed down it's still noticeably redder/bronzer than other places on my face and there is a noticeable border. What the hell happened? As far as I was told, redness should've gone away in about three days. I've barely gone outside, and when I went out I always used sunscreen. How could this have happened in the first place?
