Dark areas between nose and eye--maybe veins? (Photo)

This is normal skin changes with age and worse with allergies, there is a prominent vein there as well.  fractional laser, prp and microneedling help improve this long term but nothing will get rid of this completely.  Please see an expert in lasers.  Sometimes fillers with cannulas there can help as well.  Best, Dr. Emer.

The dark areas on either side of your nose near the eyes may be attributed to several factors, including underlying vascular conditions, skin inflammation from allergies or eczema, or even structural changes from past trauma, such as the car accident you mentioned. The deep dent could contribute to shadowing in the area, enhancing the appearance of darkness. To improve the situation, it's essential to consult a dermatologist or medical professional who can provide a thorough evaluation. They may suggest treatments ranging from topical creams to address skin concerns to cosmetic procedures, such as dermal filler, that could help fill in the dents and improve overall appearance. In the meantime, managing allergies and eczema with appropriate skincare can also play a significant role in reducing inflammation and discolouration.

The areas you are describing appear to have pigment which could be lighted, and tear through contour which could be filled in.
