I want to know about four-season skincare and skincare routines for combination skin.

My dehydrated skin is really oily and full of sebum in the summer, and extremely dry in the winter...

So, my skin always breaks out once every time the seasons change.

How on earth do people with dehydrated oily skin manage their skin?!

Especially in the summer, even if I apply it as lightly as possible, I'm really worried because oil builds up, perhaps due to a lack of moisture.

Would it be better to just apply a light lotion and sunscreen in the summer?

I'm wondering how I should apply it in the winter.

Also, when it comes to cleansing, which would you recommend more: cleansing oil or cleansing water?
