The nonsurgical treatment of valley-type tear trough (TT) deformity with diffuse depression in preseptal segment aims a more effective and safer treatment alternative to present padding techniques through the use of hyaluronic acid fillers to the preseptal space. 22G 50-mm cannula was inserted into the preseptal space, 2 cm inferolateral to the lateral canthus, and a low concentration of monophasic hyaluronic acid filler was applied. TT deformity was treated through the elimination of the contrasting subcutaneous fat tissue quality and quantity both above and below the TT, which contributes to the accentuation of the TT deformity. Valley-type TT deformity was successfully treated without any complications via filler injections to the preseptal space in which no structures pass.
