How long does the skin texture improvement effect of Skin Botox last?

Lately, my skin texture looks bad, and I'm generally concerned about my pores and fine lines, so I'm considering skin Botox.

I heard that unlike regular Botox, it is injected broadly into the skin layers to produce pore-shrinking and a radiant glow. Did you actually feel a significant improvement in your skin texture when you received the treatment? I am also curious how long the effects usually last!

I would be really grateful if those who have actually experienced this could share their honest reviews and tips, such as whether the pain is quite severe and how long it takes for the embossing (injection marks) to naturally disappear immediately after the procedure!💘
