What laneige products should i buy?

I was thinking of getting Multi cleanser, Pore Trouble refiner, Perfect Renew Essence, Hydra Solution Essence,
and Cure natural aqua gel thats not from laneige

My skin type is an oliy T-zone that has pimples on those areas. My face may be discolored since it's not brighten.My skin is oily combination. I also have alot of dark spots and dark circles under my eye
im 18 years old. I have alot of dead skin that most of them won't wash off so i might be getting cure natural aqua gel.

Since im premature aging i think i should get Laneige Perfect renew essence
my T-zone is mostly bumping with pimples.

I know Laneige dosn't cure pimples, i just want to get rid of my dead skin cells and i need a gel moisturizer so i can take good care of my skin without the harsh products.

I think Laneige is about organic products. Is that true?
