D curl lashes
explained.

In plain English

D curl is a strongly rounded profile with a more pronounced upward and backward turn than C in the same range.

What the term means.

The stronger arc contributes to a rounded outline, but does not specify a doll-eye map. Curl is the fibre shape, whereas the map decides where the design's emphasis sits.

A tighter arc can reduce forward projection at equal printed length. It also changes tip position relative to the eyelid. Review contact at the base and the visible open-eye result rather than treating a stronger letter as an automatic improvement.

These are industry definitions. Product names, profiles and availability vary; your artist selects the actual system and construction for your appointment.

A common question.

Does 5D mean a D-curl fan?

Not by itself. The five counts the fan's fibres and D means dimension. Its curl is a separate specification and could be C, D or another appropriate profile.
