Does Quadsay really work when the skin barrier is damaged?

Lately, my skin hasn't been soothing at all. My face frequently turns red, and while it looks shiny on the outside, it feels like it's parched on the inside. I've been looking into Quad Say closely because I saw online that it's non-irritating for soothing and hydration.

I'm drawn to it because there are so many reviews saying it hydrates the skin and strengthens the skin barrier. I'm really curious to see if I can actually see my complexion brighten and my skin texture improve after getting Quad Say! I'm hesitating, though, because I'm worried it might just be a one-time moisturizing effect that ends up being a waste of money.

Has anyone tried Quadsay care recently? I would be so grateful if you could share your genuine, honest reviews on how many sessions are needed to feel my skin becoming stronger.
