"This serum feels like it was made with the same mentalities we see in K beauty, where the focus is on calming ingredients and a lot of fermented ingredients. It's a super hydrating formula, it actually feels a lot like a sticky hydrating jelly except with less of that sticky sensation, and the same level of hydration. It's fragrance free, made with peptides, glycerin, gotu kola, ashwagandha, fermented tea, beta glucan, and tremella mushroom."

"The Undefined Beauty Hydro Jelly is one of the most amazing things. It's a black-owned product you can get it at Target. It comes in a bottle that's like a serum and it almost feels like a serum. You could use it as your serum step, but also if you find it to be sufficient enough for your moisturizer for the day, which, if you've got really oily skin and it's the summertime you're sweating a lot, that might be very sufficient for you."
