"It also has Alpha arbutin, good for dark spots. It's got a lot of hydrating ingredients: beta glucan, bifida ferment lysate, sodium hyaluronate, niacinamide, and 30o ethyl ascorbic acid, which is a stable form of vitamin C and may help as an antioxidant. I look forward to trying this. I haven't had great luck with Nzen. I tried a few of their serums and toners [...] a couple of years ago and they were not so great for me, but I'm going to give this a try."

"One of my favorite over-the-counter serums is by a Korean brand called Nzen, it's their Vitamin Concentrate Serum. This has a whole slew of brightening agents and antioxidants in it like tranexamic acid, glutathione, niacinamide, vitamin C, and arbutin, and to me it's one of the most affordable and effective lightening serums that exists on the market."

"The Nzen Vitamin Concentrate Serum has a high dose of glutathione alongside three different forms of vitamin C derivative and some other great brightening ingredients such as tranexamic acid. This is going to be like a hero concoction when it comes to fading hyperpigmentation and comes at a really reasonable price point. It's back in my skincare routine and I'm definitely grateful for that."
