"Love this stuff. I forget it's on. No smell, no white caste, no grease. Leaves a nice hydrated look to my skin."
Bella Solorzano
"This is one of my favorite daily sunscreens. It's lightweight, hydrating, and absorbs quickly without feeling greasy or heavy on my skin. It leaves a comfortable, natural finish and doesn't irritate my sensitive skin. I love that it provides great sun protection while also keeping my skin moisturized throughout the day. It layers well with the rest of my routine and feels easy to wear every single morning. Such a reliable, gentle sunscreen that I'll continue to repurchase."

"I use Tretinoin (Retin A) every night for acne and anti-aging, which can irritate your skin if you put it on immediately after washing. But if I wait to put it on after my skin is dry, my skin feels tight. So I love this moisturizing toner as a first step because it soaks into my skin and after 10 to 15 minutes, I can complete my night time skincare routine. I like that the green tea extract is much more concentrated than other green tea products. I like the natural smell. I love the lightweight texture. I pour it onto my hands and rub it directly onto my face and neck (forget cottonballs that soak up more product than is necessary). I like that it contains antioxidants and reduces sebum as I have oily skin. But I'm not sure it does anything for anti-aging scientifically. The best antioxidant for anti-aging is Vitamin C because it is small enough to penitrate the skin barrier. And this product touts itself as lowering sebum production. Others claim green tea prevents signs of aging. So perhaps that part is wishful thinking. Nevertheless, I am on my second bottle because it's a nice, light moisturizer that sinks into my skin, doesn't irritate it, and actually soothes my skin before I layer on all my night serums and tretinoin. This quenches my skin's thirst every night. For that reason alone I will continue to purchase it."

"This truly is the toner for oily skin. I've been using it for almost a month and I have to tell that this really helps with the excess of sebum. I have combination skin and this one is the only toner that really helps me controlling the oily T zone without leaving my face dry and it lasts all day I recommend it a 100% PD: it has a little scent but it doesn't last long, so it won't bother you"

"I absolutely love this serum! I've tried a lot of hyaluronic acid products, but this one from Isntree is on a completely different level. The ultra-low molecular formula actually sinks into my skin instead of just sitting on top, and I can feel the hydration immediately. My skin looks plumper, smoother, and way more refreshed, especially in the mornings. It layers perfectly under moisturizer, makeup, and sunscreen without pilling, and it never feels sticky or heavy. I also love that it's vegan and gentle enough for my sensitive skin. After a couple of weeks, my complexion looks noticeably healthier and more radiant. If you want deep hydration that actually works, this is definitely the serum to get. I'll be repurchasing for sure!"
Monica
"A nice lightweight hydrating serum! It also helped me with my redness (I have sensitive skin) 😊❤️ When I was done, I notice that my skin felt a little dry, so yeah, a perfect addition for dry, sensitive skin!"

About Isntree
Isntree is a Korean skincare brand founded in 2009 with a simple idea: honest ingredients make the best skincare. Before launching a single product, the founders created Korea's first cosmetic ingredient blog — analyzing formulations from a consumer's perspective.
That transparency-first approach shaped everything that followed. Today, Isntree formulates without over 2,000 harmful ingredients and maintains its own exclusion list of 100 additional substances. Every product is built around carefully sourced botanical ingredients that deliver visible results with minimal irritation.
The name — combining "Island," "Natural," and "Tree" — reflects a commitment to nature-based, environmentally conscious skincare. Since 2022, the brand has been reformulating its packaging with recyclable materials, soy ink, and FSC-certified paper.
Isntree supports inclusive campaigns, donates skincare to underserved communities, and is fully cruelty-free — no animal testing, no animal-derived ingredients.
Available in 40+ countries since 2017, Isntree has earned global recognition for products like the Hyaluronic Acid Toner, Green Tea Fresh Toner, and Watery Sun Gel.
