HD lace is more like an upgrade on transparent lace, it got super thin lace material than transparent lace(Normal/Regular lace), that's why HD lace(also called Clear Lace) is highly undetectable. HD lace blends well on different skin colors, creating an invisible hairline just like melt into your skin, in the meantime, HD lace is not as durable as transparent lace. So do not handle the HD lace roughly!
