L Curl Lashes

• Shape & Style: A straight base with a sharp upward lift at the tip.

How to Choose the Right Lash Curl

When selecting lash curls, consider:

• Natural Lash Direction – Straight, curly, or downturned.

• Eye Shape – Hooded, almond, round, or deep-set.

• Desired Style – Natural vs. dramatic.

• Retention – Curls with straight bases (L and M) often last longer for certain lash types.

Remember: You can mix different curls in one set to create depth, texture, and a more customized lash extension look.
