To treat dark circle effectively, I use cucumber because it has astringent and cooling effects that lighten my skin and boost the flow of blood as well as reduce puffiness.

- Place the mixture on the eye area with a cotton ball for 15 minutes
- Wash it off with clean water and perform once daily for 10 days
