Inquiry regarding price and duration of collagen care for skin elasticity

Recently, my skin elasticity has noticeably decreased, and I am concerned about fine wrinkles, so I am planning to start taking care of it.

Among the various treatments, I noticed there were quite a few posts about collagen care.

I am curious about the price range of a collagen care package for consistent use, rather than just a one-time cost.
Is there usually a discount if I pay with a 3- or 5-session package?

Since I am making a big decision to invest, I want to get the maximum effect at a reasonable collagen care price.

I would also appreciate your advice on whether the price of collagen care varies significantly depending on the management program configuration, and how long the effects last.
