I used PTT to control sebum in the beginning, and then used Allegro regularly to control my pores and acne. When I use a strong laser, my face gets irritated and turns red, but it actually has the opposite effect, so I prefer the mild laser even if it is less effective. There aren't any good reviews about Allegro... But I received it regularly several times. I received consultations that said it was effective for acne and pore regeneration. I searched and searched for it, so I decided to go and pay. I paid for Allegro 5 times and a pack and skin care together. I really like Allegro. Then , I felt like the counseling director at the hospital I went to was teaching me a little bit? Hahaha. He told me that I need to know what lasers are and what my skin condition is so I can get what I need without being ripped off, so from then on, I decided to get a job by choosing treatments based on my skin condition. I was so stressed out that I was upset and it was festering inside me all the time. It was no joke, but after just one PTT and two Allegro sessions, the acne calmed down. I took Allegro 5 times and will post a review of the maintenance treatment. I received them all at 3-week intervals.
