What are the features of Quadsay that differ from standard lasers?

There are more types of dermatological lasers than I thought, so the more I look into it, the more confusing it becomes.

I used to think that if blemishes appeared, they were simply removed with a laser, but I've heard that nowadays, the equipment used varies depending on the skin condition and the type of pigmentation.

Then I found out about the Quadsay procedure.

I am curious about the differences compared to a standard pigment laser, but even after reading the explanation, it is difficult to understand easily.

I am being cautious when choosing a procedure because I heard that older people have thinner skin and slower recovery.

What is the biggest difference among the features of Quadsay? I would also like to know if it can be used even on old blemishes or uneven skin tone, and if the effectiveness varies depending on the depth of the pigmentation.

I am also curious whether the Quadsay procedure is a one-time treatment or if I need to receive it multiple times.

If you tend to get scabs or experience prolonged redness after the procedure, you should adjust your schedule in advance.

Above all, I would like to know if the Quad Say procedure is suitable for the skin of middle-aged men.

Rather than receiving an unconditionally strong laser, I would like to choose a method that is less burdensome on the skin. What criteria should I use for a consultation?

If anyone has looked into similar lasers or received a consultation, I would appreciate it if you could let me know the differences.
