Who is Livihill recommended for when your skin barrier is compromised?

Lately, perhaps due to the large daily temperature fluctuations and fine dust, I feel like my skin has become very sensitive and dry. Even when I apply a generous amount of nourishing cream, it feels like it just sits on the surface, so I am looking into skin boosters. I heard that Libby Heal is really good for regeneration and brightening.

Perhaps because it contains exosome ingredients, it seems that people like me with severe internal dryness or reduced skin regeneration abilities are frequently mentioned as potential candidates for Liviheal. Honestly, I was hesitant because there are so many options, but after consulting with Liviheal, I am leaning towards it because I heard that recovery is relatively fast and the radiance lasts a long time. Is there anyone with dry skin who has tried this and found their skin glowing? I am curious to hear specific reviews on how it compares to Juvelook or Rejuran!
