I’ve had the Nd:YAG treatment for dark spots before, and the pigment seemed like it was removed through the skin’s surface as a scab. However, I recently got the procedure done again and the dark spot became slightly darker after treatment and there was the faintest hint of crusting, but it never scabbed (I believe my derm used very conservative settings). Could the pigment still be in the process of being cleared even if not through the skin’s surface (perhaps by the immune system instead)?
