What are the effects and price of Larafill? Is it okay to only treat my nose and cheeks?

I have become interested in improving the skin texture on my nose and cheeks and am looking into Lara Peel. I am curious about how the cost varies depending on the products used and the treatment area. I have small bumps on my cheeks and areas on my nose that look like sebum, but since I don't have severe breakouts all over my face, I am unsure if I need to plan for multiple sessions from the start. While the cost is important, I would like to know first if this treatment is actually necessary for my skin.

How many sessions should I generally expect to see results from Lara Peel? I am also curious whether Lara Peel is primarily for full-face care, or if it can be performed focusing on specific areas like the nose and cheeks.

If this is my first time receiving Lara Peel, would it be okay to proceed with just one session to check my skin's reaction and satisfaction before deciding whether to continue?

I would like to be informed not only of the cost but also of the expected treatment time and precautions after the procedure.

I want to manage my care reasonably, only to the extent absolutely necessary. If I need multiple sessions, I would like to compare the overall cost and treatment intervals first before making a decision.
