Jubelook Inquiry

My skin is usually dry, rough, and thin, so I was concerned about fine lines and loss of elasticity. People around me recommended Juvelook. Since they said it helps with collagen production, I was curious and tried it just once recently.

However, I have heard from others that it is difficult to see significant results from Juveluck with just one session and that you need to receive it consistently over several sessions. I am wondering what the minimum number of sessions is to see proper effects.

Also, for skin types like mine that are generally dry and thin, would it be okay to treat only specific areas like around the eyes or mouth? Or do you recommend receiving treatment evenly across the entire face? I am seeking expert advice on this. Please provide detailed information regarding the treatment cycle, frequency, and effective treatment areas!
