Why is it transparent?

鼻部皮肤较薄时，假体（尤其silica gel）在侧光或强光下可能透出轮廓；expanded相对不易显形。这与个体皮肤条件直接相关。

Light transmission itself is not necessarily a complication, but if it is accompanied by visible appearance, strong outline, and redness, attention should be paid to it. It has more to do with "matching conditions" than just surgical errors.
