Will Vitaran be effective?

I'm worried because, perhaps due to the weather lately, my skin has become extremely dry from the inside and seems to have lost all its elasticity. No matter how diligently I use moisturizing cream and face masks for home care, the relief is only temporary, and my makeup just keeps caking.

An acquaintance who is good at skincare recommended that I try Vitaran, saying that skin boosters are the best for skin regeneration and hydration. I heard that Vitaran contains salmon extract, so it helps strengthen the skin barrier. Since I have never had an injection before, I am a little scared of the pain, but I am also looking forward to it.

For those who have actually tried Vitaran, I am curious if you can really feel the effects on skin texture or internal dryness! I would appreciate honest answers from those with experience on whether it is worth the money.
