Well, I mean, when you inject fillers in, I would say yes to some extent if your body removes or dissolves away the fillers, so some people actually remove them quicker, so the effect is a bit shorter.
For instance, if we use the same products, you know in my case it might last 6 months but in your case might last one year. It could be the other way round, yours might be shorter because you are younger, and you metabolise faster.
