Bound character: it lives in 憔悴 (haggard, wan, careworn), describing a face worn down by illness, grief, or exhaustion. Learn it as the word, not the single 憔.
Left-side heart radical 忄, the upright form of 心. Looking haggard comes from inner worry and grief, so the heart radical fits the careworn sense of 憔悴.
Right side 焦 supplies the sound (jiāo shifting to qiáo) and a fitting flavor: 焦 means 'burnt, anxious', and constant anxiety is exactly what wears a face down.
