How many days after the procedure does the effect of skin Botox usually become most beautiful?

I have important photo shoots and social gatherings back-to-back next month, but my biggest skin concern is that my makeup doesn't apply at all because my skin looks dull and lifeless. I am looking for a procedure that can instantly restore firm elasticity and a clear glow to my face in a short period of time with minimal downtime. Friends have strongly recommended getting Skin Botox 2-3 weeks before important events, saying that it makes a huge difference in foundation adherence and gives you skin as smooth as a peeled egg. I am curious about the typical timeline for when the effects usually look their best after getting Skin Botox. Also, I would appreciate it if those who have tried it could share their experiences regarding whether it is safe to combine Skin Botox with a Skin Booster without any breakouts before an important event.
