How long do the effects of a collagen booster usually last?

I am writing to inquire because I am curious about the duration of the collagen booster's effects. I am looking into collagen boosters because my skin elasticity has decreased and the fine texture looks rough, but I don't really have a sense of how long the effects last after just one treatment.

I know it varies from person to person, but I’d still like to know the approximate duration of the results to help me plan my budget and schedule. I’ve heard that the effects of collagen boosters tend to develop over time rather than appearing immediately. When can I expect to start noticing changes, and for how long can the results typically last?

I am also wondering how many sessions of the collagen booster are necessary for the results to last longer. My concerns are dryness on my cheeks, loss of elasticity around my nasolabial folds, and makeup creasing, and I do not want any overly artificial changes.

I would like to know if it is possible to receive collagen boosters every few months as a maintenance treatment if I take them consistently. During the consultation, can I receive realistic guidance on the expected effects and duration of the results based on my skin condition?
