Review of fixing underarm pigmentation with a procedure (before/after photos, scab photos attached)

The pigmentation under my arms was really severe, like dirt had built up there. My skin itself is on the fair side, but the places that aren't visible tend to be pretty pigmented. Especially the bikini area and underarms, since I always got waxed, they seemed much more pigmented than areas like the knees or elbows. Brazilian waxing is basically not visible anyway, so I didn't worry much about it, but underarms are different, so I ended up paying a lot of attention to them. I'm a very clean person and my skin is fair, but only the underarm area had gotten really dark, so it bothered me even more... I tried buying whitening cream and applying it. It worked for things like tanning on the face in summer, but for underarm pigmentation it had no effect. Because it is a folded area, putting on cream made me sweat and feel sticky too.. I kept wondering what to do about this summer as well, and then by chance I came across a review of a procedure done at a clinic. I got the information, went for a consultation, and ended up getting the procedure too haha. I will post photos now showing the state after the third session. It is a procedure called Cellanin at Dermatology, and it seems the main treatment methods are stem-cell ampoules and laser. The developer of this treatment? also did the consultation, and even from the consultation, they seemed very confident, which made me trust it more. The procedure itself did not hurt at all and took about 20 minutes? 30 minutes? It was over quickly. It stings a bit when the laser is applied and the ampoule is spread on, but it was not painful. After the procedure, they also gave me a care routine and a prescription, and apparently these are adjusted differently for each person. It was very convenient because I only had to follow the instructions. I also took a photo of the scabs, and they come up like this, white and crusted. I really wanted to pick them off, but if you leave them alone, they fall off on their own, and as they come off, it seems to get a little brighter, at least that is how I felt. My complexion is quite dark, so I had the procedure three times, and I saw results from the second session. Since there probably are not many people as dark as me, I think people with only a little pigmentation might see results even after two sessions. Because the results are so good, I am even thinking of trying it on the bikini area, which I had not cared much about... lol
