I find that using a hydrating serum helps reduces the oil produced by my skin. Also have been trying out the cooling modeling mask pack, it is said to reduce skin temperature and also lessen oil produce.
I got the Torriden Dive-in Serum and Lindsay Cool Tea Tree mask from unnie.sg
Used to use Innisfree cleansing oil but doesn't like that it gives my skin an oily feel. Now I'm using Huangjisoo Cleansing Oil that I bought from unnie.sg. Feels milder and less oily.
Recent discovered EGF micro needle products. Have been trying for a week and already starting to see results.
Also find the Swanicoco peelng herb scrub to be really good.
