Pico Toning Inquiry

Hello. Recently, I have been concerned because the freckles, blemishes, and acne marks on my face, as well as my overall complexion, have worsened significantly.

After receiving Pico Toning previously, I saw results for melasma and blemishes, but I didn't feel it brightened my overall complexion. I am wondering if the number of sessions is the issue, or if there are skin types that do not see a brightening effect even with Pico Toning (I received 10 sessions at one-week intervals 2-3 years ago).

I have also recently received about 5 sessions of Pico Toning, but the improvement in pigmentation is less than before, so I would like to inquire about the cause, wondering if it is due to my age.

Also, since it is currently summer, I would like to ask whether it would be better to receive Pico Toning in a season when UV intensity is lower, or if it is fine to receive it now (although UV rays weaken in winter, the weather is dry, so that is a concern).

Although there may be individual differences depending on my skin condition, I was told that the treatment cycle is about 1-2 weeks. I would also like to know whether 1 week or 2 weeks is better.

Finally, please provide information regarding the most important aspect: cost. How much does a single Pico Toning session cost for the entire face? I have heard that toning treatments are often performed as packages, so I would appreciate it if you could also share the prices for 5- or 10-session packages, as well as any current promotions. I will visit for a consultation after reviewing your reply. Thank you.
