I recommend Goodal Vita C Blemish Care Serum.

Product Name: Goodal Green Tangerine Vita C Blemish Care Serum 30ml

It doesn't have a huge whitening effect, but since my skin looks cleaner and clearer, I think that counts as a whitening effect.

I use it at night, and once it absorbs, my skin feels firm and tight.

True to its green tangerine product, it is refreshing and cool. You can think of it as a serum packed with moisture.

I think I'll need to use it consistently to really know the effects. It's a vitamin serum with a pleasant scent and a reasonable price.

However, if I don't control the amount properly, my face feels a bit stuffy—especially on hot days! I recommend keeping that in mind when using it.
