I bought this so that I can try the viral Round Lab Dokdo toner. It's a bestseller for a reason and I totally get the hype. The toner is gentle, hydrating, and everything you want with your toner. I have no regrets about purchasing the travel set because it is indeed perfectly handy for traveling purposes, and more importantly, using them in one routine is just a chef's kiss for your skin. The cleanser does a great job of gently but deeply cleansing the skin without feeling dry, followed by the toner which gently exfoliates and nourishes the skin, and finally using the lotion to soothe, moisturize, and lock everything in.
