    Nice
    Its cool, I like the packaging as well as how much product you get for the price. It has a lightweght water-gel texture, it feels nice to apply. I dont think it helps much with redness unless you really have rosacea then maybe a little bit. But anyways, I really love this brand.

    Lightweight and gentle on sensitive skin
    I like this moisturizer a lot. It feels light on the skin, absorbs nicely, and doesn’t leave me feeling greasy afterward. The formula is comfortable for daily use, offers decent consistency, and I appreciate that it’s fragrance-free. The quality is better than expected, especially for trying a new-to-me brand. I have very acne-prone skin and a lot of products leave me red due to sensitivity, so it's nice finding one that doesn't agitate my skin. For the size and how easily it fits into a routine, I think the value is good. It’s one I’d keep around, especially when I want something simple and calming.

    My skin loves this.
    This might be the best face wash I’ve ever used, and I do NOT say that lightly. I have it on subscription because I panic a little at the thought of running out. For context: my skin has gone from oily, acne-prone chaos to “surprise! now you’re dry and post-menopausal” and somehow this cleanser handles ALL of it beautifully. It cleans deeply without stripping my skin, leaves my face feeling soft instead of tight, and somehow manages to make my skin look calmer, smoother, and less angry overall. My pores even look better. Also… the texture? Weirdly satisfying!! It has this rich, creamy feel that feels luxurious without being heavy. Now for my one complaint: The cap sucks and we are in an ongoing toxic relationship. The cleanser itself is elegant Korean skincare perfection. 5 stars!

    Smells nice and doesn't irritate my senstive skin
    Nice face wash. It removes makeup well and leaves my face feeling smooth and clean. Does not irritate my rosacea.
