I have a question about the effects and duration of skin Botox.

recently I feel that having naturally smooth skin is more important than applying heavy makeup. However, as I started becoming concerned about my pores and fine skin texture, I feel that home care alone has its limits, so I am comparing various treatments. Skin Botox caught my eye, but I am curious if the timing of when the effects appear and the duration of the results vary significantly from person to person. I am also unsure yet how much change I can expect from just one treatment, or if I need to repeat it at regular intervals. While I see reviews saying people were satisfied, I suspect the results can vary depending on skin condition and the treatment method. Therefore, rather than deciding on the number of treatments right away, I would like to confirm its suitability through a consultation first. For those who have received the treatment, what changes did you notice first when assessing its effectiveness? I would also appreciate it if you could share the factors you considered when deciding on the duration of the results or whether to undergo repeat treatments.
