Diagnosis Before Treatment

Conditions, Explained Honestly

Treatment names change; problems do not. These guides start from what you see in the mirror — and explain what is happening underneath, what the evidence supports, and what nothing can do.

The classification physicians use — icepick, boxcar, rolling, plus raised hypertrophic scars — exists bec…Jowl Fat vs Jowl SaggingNot every jowl is sagging. The lower face carries discrete, named fat compartments — and in some faces the jowl is primarily a fat pocket sitting alon…Buccal Fat & the Persistently Round FaceThe buccal fat pad is a deep, walnut-sized fat structure in the middle of each cheek — distinct from the fat under the skin, and largely indifferent t…Double Chin: What's Actually Under ThereA double chin is rarely just fat. Under the chin, four contributors stack: a submental fat pocket (above or below the muscle layer), skin laxity, the …Eye Bags: Puffiness, Prolapse or Shadow?An eye bag is one of three things: orbital fat pushing forward against a weakened restraining wall (a true bag), fluid that pools and shifts (morning …Droopy & Hooded EyelidsA heavy upper lid has three possible authors: excess, lax lid skin folding down (dermatochalasis — the common 'hooding'), the lid itself sitting too l…Upper Lip Lines (“Barcode Lines”)The vertical lines of the upper lip — barcode lines, smoker's lines, lipstick lines — are etched by four forces at once: a purse-string muscle that cr…Forehead Lines & Frown LinesThe forehead's horizontal lines and the vertical '11s' between the brows are muscle handwriting: the frontalis raising the brows and the glabellar com…Thin Lips & the Ageing LipLips thin two ways: some were always slim (genetics), and all deflate with age — volume shrinks, the pink vermilion rolls inward, the white upper lip …Square Jaw & Masseter BulkA wide lower face has three possible materials: masseter muscle (the clenching muscle at the jaw angle, enlarged by use), bone (the mandible's own arc…Flat Nose Bridge & Profile BalanceA low nasal bridge — common in East and Southeast Asian anatomy — flattens the face's central axis in photographs and glasses slide down it all day.
