When will the definite effects of laser hair removal appear?

Even though I shave cleanly every morning, I am left with bluish marks on my chin and philtrum, and my skin keeps getting damaged, so I am considering getting laser hair removal. I have high hopes because I heard that consistent laser treatment at a professional dermatology clinic significantly fades beard stubble and smooths out skin tone. Typically, how many regular visits are required for laser hair removal before the hair starts to decrease noticeably? I suppose it would be difficult to feel the effects or changes immediately after just one or two sessions, right? It would be a huge help in making my decision if you could share honest reviews or the process of hair reduction from those who have actually undergone the procedure!
