The treated side exhibited a noticeable stillness during expressions, a lack of the natural creasing that accompanied smiles and frowns on the untreated side. This smoothness, while often desired for its anti-aging effect, stood in stark contrast to the dynamic movement visible on the other half of her face. The subtle lines around the eye, the gentle furrow of the brow – these remained present and active on the untreated side, serving as a constant reminder of the natural elasticity and expressiveness of the facial muscles. Therefore, by carefully observing the dynamic movements and the presence of subtle lines during facial expressions, one could confidently deduce that the side exhibiting natural creasing and movement was indeed the untreated side, while the remarkably smooth and still side bore the clear evidence of Dr. Bita Zadeh Farrell's unilateral Botox application.
