Does the effect differ if I get Rejuran and Skin Botox together?

I am looking into Rejuran and Skin Botox because I am concerned about my rough skin texture and fine lines. I have heard that receiving both treatments together improves the skin, but I am not sure about the difference. I am confused because I heard that Rejuran focuses on regeneration, while Skin Botox is good for pores and fine lines. Since my skin tends to be sensitive, I am worried that getting multiple treatments at once might worsen redness or dryness. What effects can I expect from getting Rejuran and Skin Botox together?
