Most people judge whether a treatment worked by comparing a bathroom selfie to a memory. Under-eye shadow is the single most lighting dependent feature on the face, which means the usual method is guaranteed to produce a wrong answer in one direction or the other.

§ 04 · Frequently Asked
Dark circles have four main causes: vascular (visible blood vessels through thin skin), pigmentary (melanin deposition, often genetic or post-inflammatory), structural (volume loss creating shadow), and anatomic shadow (a hollow under the orbital rim). Most patients have a combination. Identifying which type drives your appearance determines effective treatment.
