What skin type is Livihill recommended for?

Lately, I have been frequently told that my skin looks unusually dull and lacks elasticity. In particular, even if I apply makeup in the morning, my skin quickly looks dry by the afternoon, and the overall lack of vitality is becoming severe, so I feel the need to take better care of it. While searching for alternatives, I came across many reviews for Livy Heal, and there were many comments about high satisfaction regarding improvements in the skin barrier and internal dryness. However, I am curious about exactly which skin types Livy Heal is recommended for. Since my skin is thin and sensitive, I am always very worried when getting a new treatment, so I would like to know if Livy Heal tends to be quite irritating. Also, I would like to hear reviews from those who have actually experienced it regarding changes in skin texture and how long the results last after the treatment.
