Hydrocortisone on the nose is not cope, here's why:
The main argument for why it's "cope" is often: "Muh but 80-90% of the nose is composed of cartilage!" While that's true, hydrocortisone can also degrade cartilage over time, not just skin.
Now, remember, this isn't going to yield anything close to the results of a rhinoplasty, or injections, so don't get your hopes up, although it does give solid results.
Study showing the effects of hydrocortisone on cartilage:
Obviously, topical hydrocortisone is vastly different from injections. However, it is still absorbed into the bloodstream, and while only a small percentage of the applied dose is typically absorbed, it will still have the same effects, although on a much smaller scale.
Study showing atrophy of the skin from topical hydrocortisone:
Hydrocortisone, a topical corticosteroid, affects the skin layers by reducing inflammation, However, prolonged or improper use can lead to thinning of the skin.
For topical application, here are your best options for achieving optimal results:

Study showing the effects of hydrocortisone on cartilage:
- Detrimental effects: However, at higher doses, hydrocortisone can have detrimental effects on cartilage, leading to gross cartilage damage and loss of cartilage.
- Chondrocyte toxicity: Studies have also shown that high doses can be toxic to chondrocytes.
- Increased risk of osteoarthritis progression: Research on intra-articular corticosteroid injections (which deliver a higher local concentration of the steroid) has suggested a link between these injections and accelerated cartilage loss, potentially leading to faster osteoarthritis progression.

The Deterioration of Articular Cartilage in Osteoarthritis by Corticosteroid Injections - Journal of Prolotherapy
By Ross A. Hauser, MD ABSTRACT The hallmark feature of osteoarthritis is the breakdown in the articular cartilage of joints such as the knee and hip. Both animal and human research has consistently shown that corticosteroid injections into normal and degenerated knees accelerate the arthritic...
