I read a lot of the reviews and people described the sheets rough on one side . It's not rough AT ALL. It's more slimy / moist on one side. But definitely not rough on the other side. I was expecting to get a better dermabrasion from this. So that I don't think I can get...but I hope I get the lightening of the skin as people says. It leaves skin soft.I appreciated that everything is perfectly sealed.

Here are the things I like about numbuzin's glutathione+niacinamide pads:Brightens skin and fades sunspot: I find these pads really does wonders to my sunspots and my skin tone overall. However, it doesn't happen overnight (at least for me). It is a gradual process and one has to use it religiously.No irritation: Even though these pads are fully soaked, it doesn't irritate my skin. The ingredients feel quite gentle and non-invasive on the skin.Double-sided pads with dual functions: one side is smooth and a little slimy; one side is quite coarse, which is meant for exfoliating. Personally, I only use the smooth side because I find the coarse side too rough for my skin type.Convenient packaging: these square facial pads are fitted inside a square plastic box with a small tong stored on the lid.In conclusion, as someone with sunspots, I do see my sunspots have become lighter over time, emphasizing on the words "over time". For me, it took about a good 6 months to see the real effect. And my skin tone has become brighter as well. In addition, I also use numbuzin's facial lotion after the toner pads. So I don't know if it's the combo that works or just the pads alone. But I definitely like the feel of these pads on my skin.
