I was worried about freckles and red marks, so I tried Sylfirm X at Gangnam GU, and I understand now why it's such a famous treatment. Honestly, I didn't have high expectations at first, but after a few weeks, my skin tone started to look clearer overall.

When I apply makeup, my skin looks much cleaner than before, and the dull look seems to have diminished significantly.

I was most satisfied with how smooth my skin texture became.

I still have a few more sessions left, but I can feel my skin improving every time I look in the mirror, so I plan to continue getting the treatments regularly.
