Let me introduce the ampoule I use.

This is an ampoule I currently use; its name is the Sea Soap Brightening Ampoule. Best of all, I love that it comes in a generous 50ml size. Although my skin is usually runny, this one feels incredibly light. Since I have very sensitive skin and breakouts, I can't use anything unless it's gentle, but this is so light and great. I bought another bottle and gave one to my mom as well. It's such a good ampoule that I wanted to introduce it to you. The scent is subtle but not too strong, so I think it will be pleasant to use. I highly recommend this ampoule.
