Hi! I just want to know if my skin is irritated or not. I just need to know what is going on with my skin.

background:
Currently, I am going through some blood test to find out what is going on with my hormones (i've had my period for 3 weeks and have never had a regulated period). I have an IUD in right now (copper) so i don't have any hormones regulated. Other than that I've always struggled with acne. ALWAYS. I cannot read my skin anymore. There was one day a couple years ago my whole face flared up with cystic acne and it has never been the same since.

my question:
I am trying a new product which is reneerouleau anti-cyst treatment which has lactic acid (known for purging) my face is covered with closed comedones and cystic acne. After using it for a couple of days the closed comedones has turned in pustular acne and some of my cystic acne has a pustular top. Does that mean my skin is currently purging due to the product?
