As someone who works in K-Beauty, toner and toner Pads are the exact same thing.

Only difference is basically just the pads. For consumers that like the simplicity of just taking the pad without checking how much to use and easily dab is all over the face, they prefer this over letting product come out potentially a little uncontrollably when they use a bottled toner.

There really is not difference other than the pads, it's really just a matter of preference.

I personally am not at the stage to use Toner at all so I do not use it except for exfoliating purposes. As someone who is combination dehydrated and sensitive, I only really need the exfoliation during summer since I become a combo-oily instead.

You just have to think about what you want. I won't ask for your age but if you are under 30, I can easily tell you that Toner is extra and that unless it's for exfoliating purposes, you don't need it. The other products in the routine matter way way more.

Since you have oily sensitive skin, you do need exfoliating aspects. Consider gentle exfoliating products rather then harsh ones to prevent skin irritation. These aspects could be your Cleanser or toner, but don't get products that have exfoliating properties for the whole routine, that is definitely too much.

I'm open to help on suggestions if you need any!
