How to Choose the Right Lash Curl

Buying lashes without understanding curl is like buying jeans without knowing your size. You might get lucky, but you’ll probably end up with something that pulls or pokes. Here’s your fit guide.

What Is Lash Curl Anyway?

Lash curl refers to the shape that the lash fibre has been set into. It controls how much your lash sweeps up and away from the eye. A J curl barely moves; a D curl looks like a full-on fan. The curl type is usually printed on a lashes box as a letter between J and L, and each one changes the look of your eye in a different way.

The 4 Lash Curl Types You Need to Know

• J curl — a slight, natural lift. Best for straight lashes or monolid eyes. It won’t open hooded eyes much.
• B curl — a soft bend, like mascara after a couple of coats. Best for an everyday, “my lashes but better” look. Good for deep-set eyes that don’t need extra drama.
• C curl — the classic all-rounder. It curves upwards noticeably and opens up the eye. Best for hooded eyes, round eyes, and anyone who wants a flattering lift.
• D curl — a strong, dramatic curve. Best for deep-set eyes, photoshoots, or when you want that “fierce” look. It grabs attention.
• L curl — a flat base followed by a sharp upward angle. It’s perfect for monolids or Asian eye shapes, because the base sits flat on the lid, and the tip lifts off without poking your crease.

That’s five, not four — I always add L because it’s the secret weapon for flat lids.

How to Match Curl to Your Eye Shape

• Deep-set eyes: go for C or D curl to pull the eye forward and make it look more open.
• Monolids: L curl is your best friend. It sits flat against the lid but the sharp lift still opens the eye.
• Downturned eyes: use a D curl at the outer corner to visually lift the end of your eye.
• Hooded eyes: C curl is the sweet spot. If your hood is heavy, try D curl with a shorter length so it doesn’t bump against the skin.
• Round eyes: C curl keeps them round and bright without going overboard.

Your Questions, Answered

What lash curl is best for round eyes?

C curl. It opens the eye without making it look even more round. Avoid dramatic D curl at the centre, as it can make round eyes look a little startled.

What is the difference between C and D curl?

C curl is a smooth, moderate curve that looks like a natural curl. D curl is stronger with a higher, more defined lift. D is often described as “dramatic” but still comfortable for everyday if you pick a natural length.

Should I choose a stronger curl if I wear glasses?

Yes. Your frames can flatten the look of your lashes, especially if your lenses are cloudy or have an anti-reflective coating. A stronger curl like C or D will help your lashes appear above the frame line.

What to Look For in a Curl That Holds

The best curl in the world won’t hold if the lash fibre is heat-sensitive or the band is weak. Look for lashes made from PBT or high-twist fiber — they keep their curl even after a day of wear. Also, check that the curl is consistent across the lash. A crooked curl will make the lash look messy on.
