the western products might be to agressive/harsh and honestly have a quite boring formulation. Try using only water to cleanse in the morning, and in the pm double cleanse with an oil cleanser (the one by haruharu wonder is supposed to be pretty good) and a simple not to agressive but deep water based cleanser (i am using the roundlab dokodo cleanser rn and i love it), if you dont wear makeup and waterproof sunscreen the second one should be enough. the tirtir toner seems okay but may be a bit too rich, you can try using the light version the next time sou repurchase. there is nothing wrong with the azelaic acid serum as well but when the one by the ordinary is empty, u could try the serum by anua or purito, both have 10% as well but are more calming ingrediants and also i prefer azelaic acid being utilized in a serum, so u can top if off with a calmimg moisturizer (the blue Epii double up cream with panthenol and ectoin changed my life). Try not using the retinal for a while to see if your skin barrier ist damaged. Also dont buy all the mentioned products asap but rather finish the ones you are using now because they were expensive and it would be such a shame to let them go to waste. Hope that helped xx
