Thoughts on my way back after booking my 5th Pico Toning session

I booked my 5th session today. When I compared photos after my 4th session, I could definitely see that the pigmentation had faded, so I booked this time with high expectations.

When I first started, I was at a loss as to how many sessions I needed, but now that I can physically feel the effects improving with each session, it actually makes me want to work even harder. I've also become much more meticulous about applying sunscreen than before.

One concern I have is how much maintenance I need to do even after the 5th session. I plan to ask the doctor next time how I should schedule the treatments to prevent the pigmentation from reappearing. I want to keep receiving treatments diligently to maintain the improvement in my skin.
