01Bone shape
Some foreheads are simply flatter or have a dip just above the brows. This is structure, not ageing, and it has usually looked the same since your teens.
How a doctor tellsThe doctor looks at your profile and feels the brow ridge and the line from forehead to nose. If it matches old photos, it is structure.
02Thin soft tissue and volume loss
With age, fat under the forehead and temples thins, so the brow area looks more hollow and the forehead loses its soft curve.
How a doctor tellsComparing current photos with ones from five or ten years ago, and pinching the skin to see how thin the layer is.
03Lines that read as dents
Deep horizontal forehead lines can make the surface look uneven even when the shape is fine.
How a doctor tellsThe doctor checks whether the lines deepen when you raise your brows and fade at rest. Movement lines respond to botox, not volume.
04Lighting and hairline
A high hairline or a pulled-back hairstyle can make a normal forehead look flat and broad in photos.
How a doctor tellsLooking at you in different light and with your hair down. Sometimes the answer is that there is little to treat.
