How to Choose the Right Lash Curl: C, CC, D, M, and L Curls Explained

By linh nguyen

Understanding curl geometry is what separates basic lash applications from high-end bespoke lash design. Each curl profile serves a strategic purpose in lifting, shaping, and transforming the client’s eye structure.

The Standard Curls: B, C, and CC

B Curl: A subtle, natural lift ideal for clients with upward-facing natural lashes who want a barely-there look.
C Curl: The industry’s most popular all-rounder. Mimics the lift of a high-quality eyelash curler.
CC Curl: Slightly curlier than C, offering noticeable open-eye glam without touching the eyelid.

The Dramatic Curls: D and DD

D and DD curls provide maximum upward lift and a vibrant doll-eye finish. They are perfect for clients whose natural lashes point straight out or downward.

The Specialist Curls: L and M

L and M curls feature a flat, straight base that transitions into a sharp 90-degree or 110-degree curve. They provide unmatched contact area for straight or downward-pointing natural lashes and create crisp, lifted feline eyelines on hooded lids.
