Can people in their early 30s also experience the effects of a collagen booster?

I'm asking because I'm curious if someone in their early 30s can still feel the effects of a collagen booster. People around me still say my skin looks fine, but you know how you can definitely feel the difference yourself, haha.

My skin feels less firm than before, and on tired days, my cheeks and the corners of my mouth seem to look slightly sunken. However, I find procedures like fillers that immediately restore volume a bit daunting, and since I want to manage my skin to make it look healthier, I looked into collagen boosters. At what point is it best to start using a collagen booster when a loss of elasticity becomes noticeable?

I am curious if many people seek consultations for preventative purposes. If collagen boosters focus on improving skin elasticity and fine texture from within, I think they would be suitable for someone like me who is already showing signs of early aging.

If it is difficult to judge after just one session, I would also like to know how many sessions are typically required to see results. Could I consult with you regarding whether receiving treatment at such a young age is excessive, or if it would be okay to start gently now?
