"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. You do need to use it twice a day in order to maintain those results and get the long-term payoff, so you have to be more consistent with this than some other treatments, but I kind of think it's worth it and with the price point it definitely makes it really easy to do so."
