does accutane actually shrink ur nose?

Yeah, it shrinks your sebaceous glands (oil-producing glands in your skin). It can also reduce overall skin thickness and oiliness, but don't expect extreme changes.
Similar options would be like:
- Retinoids (tretinoin, adapalene) -- Similar idea to isotreinoin (Accutane) but milder.
- Niacinamide -- Helps control oil production and can minimize the appearance of pores, which could make the nose look less "bulky" visually.
