Estra Theracne Active Serum

This is a serum I frequently use, as I have oily skin with large pores. It is a famous Estra product, and I have seen some effect in reducing acne. I tend to get acne easily in the summer because my skin produces a lot of oil, but I liked that the breakouts decreased significantly, perhaps because this product contains exfoliating ingredients. Also, since the oiliness has decreased, it seems to have the effect of making my pores look smaller.
