The Vita A Retinol Shot Tightening Serum

This has 0.1% retinal, nine kinds of peptides, and 1% panthenol. So, you're getting anti-aging and barrier support in one.

This is more lightweight.

I found personally this one much more strong on my sensitive skin and because it's so lightweight, you can go a bit over the amount you need. But, if you can control the amount well, it is actually really effective.

It tightens the pores, makes the skin much more firmer.

If you want an effective Korean retinal/retinal products, highly recommend these.
