It has excellent moisturizing power, but is not sticky and penetrates into the skin smoothly, leaving it one tone brighter. Since it's an all-in-one product, you can use it on its own, but I also add lotion and serum depending on my skin condition.
I bought the mini size at the store. I'm so sensitive that Minon makes me itchy, so this one also irritated my skin. I think it's good for people with sensitive skin.
I used to love the [Man] before it was renewed, but it was discontinued. I asked a Kao staff member if there was anything that could replace [Man], and they told me, "Sumi," so I bought it and used it. It had a matte finish, a different texture, and was a completely different type of serum from [Man]. However, [Ming] has a lighter texture than [Man], but the finish is heavy, which I think is similar, so if I were to continue using it, I would choose [Ming] over [Sumi]. However, sometimes I would get flaky skin when I applied sunscreen on top.

I used it all!!! I was glad to see that my skin became moisturized, toned, and beautiful when I used it morning and night. However, I'm a little concerned about the cost-effectiveness, so I'm not sure if I'd buy it again... I used it all in just under two months, so maybe a smaller amount would have been better (;;)
