Is Vitaran generally satisfactory even for those with dry skin?

Recently, I've felt my skin has become much drier than before, so I've become interested in skin booster treatments. I usually apply moisturizer frequently, but I sometimes experience severe skin tightness when the seasons change or my condition deteriorates. So, I've been looking up reviews for Vita, and I became curious because there are many comments expressing satisfaction with improvements in skin texture and hydration.

However, while reading reviews, I've seen mentions that satisfaction varies depending on skin type, so I'm curious about actual experiences. In particular, I'd like to know if satisfaction is generally high even for those with dry skin. My skin isn't oily, but it tends to feel tight quickly after washing.

Also, there are many reviews stating that the skin looks moisturized after receiving Vitaran, so I am curious to know how long that feeling actually lasts. If there were people who hesitated to get the treatment due to dryness, I would like to hear what aspects they found most satisfying.
