Your concern sounds mainly dynamic: the tip may rotate downward and the nostrils may flare when you smile. The photos cannot determine whether this is due to depressor septi nasi or alar muscle activity, cartilage and skin anatomy, or simply normal expression, so candidacy cannot be decided from images alone. If the nose looks acceptable at rest, a specialist might discuss a very conservative, temporary botulinum-toxin treatment for selected muscles; it must be placed precisely and can cause an asymmetric smile, upper-lip weakness, or other unwanted changes. If drooping or widening is also present at rest, limited surgical options such as tip support/rotation or alar-base modification may be considered, but they carry risks and could change a nose you otherwise like. Please see a board-certified facial plastic or plastic surgeon for an in-person exam, including your breathing and stable goals, and bring both resting and smiling photos or video. Do not proceed based on these photos alone.
