Laneige Radiant Sea Brightening Serum

In the past, I only used skincare products—that is, until I started using Laneige Radiance C Brightening Serum. As I got older, I began getting melasma and blemishes, so after doing some research, I heard that applying vitamins to the face is beneficial. That is why I started making sure to use it regularly. The downside is that I have to buy it frequently because it expires quickly after opening, but it doesn't seem to be causing any new melasma.
