Skin Botox Duration of Effect and Cycle

I am considering getting Skin Botox because I heard it is effective for improving fine lines, shrinking pores, and refining skin texture. However, I have heard that unlike regular Botox, Skin Botox is injected shallowly into the dermis layer, so its effects last somewhat shorter, around 3 to 4 months. I am curious whether those who have actually received the treatment feel that the effects drop significantly after about 3 to 4 months, or if the duration seems to gradually increase with consistent, regular treatments. Additionally, I would appreciate your opinion on how long bruising or swelling lasts without interfering with daily life, and what is the optimal interval for treatment management to minimize stress on the skin and be the most efficient.
