Is there any procedure to decrease the alar crease prominence? (photos)

Hi SpiceMix! Thanks for your question. Dr. Walter Joseph here from sunny Beverly Hills, CA! As we age, we lose bone density and develop some soft tissue atrophy in what's called the "pyriform" area of the nose, which is the structure deep to the alar crease that you're describing. Also, some people (regardless of age!) have a genetically deeper set pyriform than others, which can also make the alar crease more pronounced. A nice treatment for this is to inject a thicker hyaluronic acid filler deep onto the bone of the pyriform in the crevasse just beside the ala. This helps build up this area and lessen the depth and the shadowing caused by the depth in this area. I hope this helps!
