I am in my 40s and would like to know what to check before a consultation for pigmentation laser treatment for brown blemishes on the back of my hand.

As I entered my 40s, I am concerned that brown blemishes on the backs of my hands are becoming more noticeable than on my face. Since this area is frequently exposed to sunlight, I may have neglected sunscreen, as they seem to be increasing one by one like moles. I am wondering if I can consult about pigment laser treatment for these brown blemishes on my hands, just like I do on my face, and how the types of blemishes are classified during the consultation. Because the skin on this area is thinner and drier than on the face, I would like to know in advance how long scabbing or redness lasts after the procedure, and whether it interferes with daily life or household chores like washing dishes. I would also like to confirm the typical number of sessions, the intervals between them, and how to protect myself from UV rays after the treatment. I am also curious if I can discuss the issue of prominent veins on the back of my hands during the consultation. Please let me know if there is anything I should prepare for the initial consultation.
