There is a saying that cucumber application can not only replenish water, but also whiten the skin.
In fact, cucumbers do not have that much effect on skin.
First of all, let’s talk about moisturizing. The skin itself has a layer of barrier, which blocks things from entering like a city wall. Even if you soak your face in the whole Pacific Ocean, it will not have the effect of moisturizing, let alone just a few cucumbers.
Besides whitening. The content of vitamin C, which claims to have whitening effect, in cucumbers is very limited, so limited that it has no effect.
Generally speaking, cucumber application can neither replenish water nor whiten the face.
