How should I schedule my collagen booster use?

I am writing to inquire about the collagen booster cycle.

I have an important event about two months away, so I am looking into ways to make my skin look a little less dry and firmer before then.

It doesn't seem like a procedure where you see immediate results after just one treatment with a collagen booster, so I'm not sure if I should start early.

I am wondering how often and at what intervals is it usually done? My skin is thin and dry, and I am concerned because my cheeks and the area around my nasolabial folds look sunken compared to before.

I am still hesitant about instantly adding volume like fillers, and I want a treatment that naturally improves skin elasticity.

When would be the best time to go for my first consultation to receive the collagen booster before my scheduled appointment? I am also curious how many days redness or marks might last after the procedure!!!
