The moment I saw the result, even with the initial swelling, I could tell the shape was exactly what I wanted

The moment I saw the result, even with the initial swelling, I could tell the shape was exactly what I wanted. It’s a great feeling. My goal was a more defined tip, and that's precisely what the surgeon delivered using an open approach. The whole process was smooth, and the staff were genuinely caring. The most difficult part of recovery so far is just having to sleep upright, which is temporary. A huge bonus is that I am breathing perfectly through my nose already. I am so grateful for the surgeon's skill and the clear communication from the team.

The conversation with my surgeon before the procedure made all the difference

The conversation with my surgeon before the procedure made all the difference. He was respectful of my gender identity and carefully explained which technique would be best for my body, taking the time to discuss my chest masculinization goals. I opted for a result without nipple grafts, with a plan to get tattoos later. So far, my recovery is going about as expected. The clinic has been great about staying in touch. It was also a relief that there were no additional expenses on top of the original price. Everything was straightforward.

Everything was communicated well, and done efficiently.

He actually sketched out the future shape of my beard and showed me photos of his previous work, which immediately cleared up any doubts I had

What gave me the most confidence was the conversation I had with the doctor before the procedure. He didn’t just listen; he actually sketched out the future shape of my beard and showed me photos of his previous work, which immediately cleared up any doubts I had. The doctor personally carried out the entire transplant procedure, transplanting 2,000–3,000 grafts using the DHI method. Now, whilst I’m recovering, I feel better than I expected. The support from the clinic is a great help: they’re always available, take an active interest in how I’m feeling, and provided clear aftercare instructions. There were no hidden charges. If you’re planning to have the procedure, bear in mind that you don’t need to bring anything special with you; they’ll provide everything you need on the day.

Everything was brilliant, the staff were brilliant, and the doctor was a real charmer! As it turned out, the person accompanying me actually had a shared history with my home town. Everything was top-notch! And the most important lesson I learnt was how skilfully they sold me their service! As we work in the service sector, this is an invaluable lesson.

Everything went smoothly

My consultation with the surgeon was clearly. He was very honest about the level of breathing improvement I could expect, which I appreciated, and it was reassuring that he personally handled both the initial meeting and my septoplasty with rhinoplasty. I’m still in the early stages of healing, but I'm feeling better than expected. The procedure was done under general anesthesia. The support afterward has been solid; the clinic gave me a clear aftercare guide and the staff has always been easy to reach. It was also a relief that there were no additional expenses beyond what was quoted. Everything went smoothly.

Everything was beyond expectation, from the online support until the day we came back was everything great, no worries about anything, the staff was lovely, the doctor make you feel very comfortable with everything, and translators were really kind. Felt very safe every step of the way.
