Ariana Grande make it clear that a nose job may have reduced the size of the tip of her nose. Before plastic surgery, the tip looked more like a ball, but now it's more slender and petite. Even though it's a very small change, it's enough to say she's gotten a nose job.
With her new eye shape, Ariana Grande always looks hopelessly confused - which is her mantra now.
Back to the nose job though... it definitely looks like she had some subtle work done.
Apart from her nose, the shape of her eyes completely changed shape. That's a weird type of plastic surgery to get, but effective none the less. The shape of her eyes pretty much defines her whole innocent/naive/gullible persona. She actually looks much more sharp witted in the before picture.
There was definitely a major shift in her appearance around age 15 or 16. Plastic surgery changed the shape of her eyes and nose quite significantly.
If Ariana Grande got plastic surgery, it was primarily focused on only the tip of her nose and not the bridge.
The interesting thing about Ariana Grande's nose job is that the tip and bridge of her nose are still pretty prominent. It just looks like the tip is slanted down more and it's less of a ball shape. The bridge still has a small bump on it though.
