1) Wetness is the essence of life
Skincare brands are starting to put a lot more thought into what is almost always the first ingredient in their formulations: water. Instead of distilled, “there’s a big push for using mineral-rich waters so that the base is also an active ingredient,” says Yoon, whose shop stocks Cremorlab, a line that uses an exclusive thermal water with rare minerals like zanadium. This water, according to Yoon, “has been found to be so beneficial for the skin that it’s used in hydrotherapy treatments for cancer patients.” Newly launched skincare brand Appriya is also harnessing the power of minerals, using exclusive water with a neutral pH balance from the Thai mountains. The silica and hydrogen peroxide in it strengthen nails, brighten hair and clear up acne and inflammation.

2) Sparkling or still?
Carbonation isn’t great when it comes to drinks, but it’s all the rage in mask and cleanser form. “Carbonated face baths, like this one from Innisfree, are a popular cleansing trend,” says Kim. “The process involves dunking your face into a bowl of water for 30 seconds to a minute using a 1:1 ratio of carbonated water to normal tap water. This invigorating cleansing technique, which originated in Japan, was discovered and popularized by Korean celebrities for its ability to deep clean your pores. The bubbly fizz is known to have toning and firming benefits for your skin, as well.”
3) Feed your skin with seaweed
The benefits of kelp extend beyond the diet realm—turns out, according to Kim, “fermented sea kelp is packed with vitamins and nutrients known to combat acne and hyperpigmentation.” Beauty brands like Tonymoly are taking sheet masks up a notch by ditching traditional cotton and creating sheets out of real kelp for even more potent hydration delivery.
