Hi and welcome to our forum! From your photos, I note that there is a droop of the nasal tp with prominence of the nasal columella. The nasal tip is broad and rounded. The nasal bridge is slightly high. A "light reflex" is the name given to the reflection of light from the nasal bridge in a photograph with direct lighting. Your "light reflex" suggests nasal bone displacement as it is not a straight line. If you only wish to correct the tip, a tip rhinoplasty will elevate the tip, add tip definition, and thin the columella. Nostril size can be reduced with wedge excisions at the nostril base. If there is displacement of the nasal bones, a full rhinoplasty would be required. Visit a board certified plastic surgeon for evaluation, examination, and discussion. Best wishes...
