Serum, toner, moisturizer. Tell me your top stable!!!

What's your favorite Korean product stable? Top 3

Some bumps on face and small white pimples after using some peach toner and vitamin c serum. Could this be a cause? Been using it previously for 7 days and was OK.

Rashes all over chest and some on face.

The cons of this product is that it dries your skin after several hours. And you would need moisturizer underneath. HOWEVER, it pills on top of a moisturizer. No matter which one I used it pills no matter what. So it's a sunscreen to wear alone not in conjunction with any skincare. It's a loner for low maintenance people. 

A light skin tint that's low maintenance daily wear. It's easy to spread on evenly on face. It's Watery which is great for oily skin ans summer heat. High spf protection. Looks natural and dewy. Leaves the skin a natural healthy glow.
