What's the Difference Between 3D and 4D Lashes?

Your natural eyes can only be enhanced perfectly by lash extensions. With 3D and 4D lashes, you can customise your look. But what's the difference between 3D and 4D lashes?

This blog post will look at what makes up 3D and 4D lashes, explain what they are, and suggest how they can be used for the best effect. We start at the beginning with an explanation of a classic 1:1 lash and then move on to 3D and 4D lashes.

What's a classic lash extension?

A lash extension sounds like something added to the end of your natural lashes for length. This assumption is not as crazy as it sounds, but it’s not the case. Your lash technician will add your extensions to your lash line with a semi-permanent adhesive. The classic 1:1 lash involves one false eyelash being applied to each of your natural eyelashes - side by side.

What are 3D lashes?

3D lashes refer to having three individual extensions applied to one natural lash. It results in a thicker and fuller look that adds volume and dimension to the eyes. It's an ideal choice for those with sparse or thinning lashes, as it considerably increases their overall appearance. You can also opt for 4D lashes, giving you even more volume but maintaining a natural-looking effect.

What are 4D lashes?

4D lashes take things one step further. 4D lashes refer to having four individual extensions applied to one natural lash and are the highest volume option available before you get into 5D plus. 4D gives you a dramatic, head-turning look with maximum impact for special occasions or for those who love a bolder style. In addition, you can use 4D silk fibre lash mascara over the top of 4D lashes to add even more depth and definition to your eyes.

3D lashes vs 4D lashes - what should you choose?

The choice between 3D or 4D lashes is all down to personal preference and the look you're trying to achieve. If you're looking for a subtle, natural-looking enhancement, then 3D lashes are ideal. However, if you want maximum volume and drama, then 4D lash extensions would be better suited to your needs.

Ultimately, it's important to remember that both 3D and 4D lashes are semi-permanent treatments and should be applied professionally with quality products for optimal results. Taking time to research reputable salons in your area will ensure that you get the best lash extensions possible.

Which eye shape suits 3D lashes best?

3D lash extensions are suitable for all eye shapes. However, they will look slightly different depending on the individual. For example, 3D lashes are ideal for hooded eyes, as the extra volume helps to create an open and defined effect. On the other hand, almond-shaped or round eyes can benefit from 3D lashes, giving them a fluttery, youthful appearance.

Eye shapes that suit 4D lashes best

Like 3D lashes, 4D lashes can also benefit all eye shapes. However, 4D lashes are particularly effective on deep-set eyes, as this look creates a fuller and more defined effect. It can also help to draw attention away from any deep wrinkles in the area.

4D extensions will provide the perfect volume for those with monolid eyelids without making your eyes appear overly large or unnaturally rounded. For best results, it's recommended that you speak to an experienced technician beforehand and discuss what kind of look you're hoping to achieve and go from there.

Are 3D and 4D lashes hybrids?

People often ask this question, and the answer is hybrids are a combination of 3D and 4D lashes. Hybrid lashes are a unique blend of traditional 1:1 lash extensions coupled with 3-4D volume, creating a fuller look that maintains a natural appearance.

Hybrid lash extensions can last up to three weeks and should be applied by an experienced technician for the best results.

What are pre-fanned lashes?

What are pre-fanned lashes? This is another question we get asked, and we know all the terminology can sometimes be confusing - so to explain, pre-fanned lashes are also known as volume or Russian lashes. The difference between regular 1:1 lash extensions and pre-fanned lashes is that the latter have multiple lash extensions already attached in a 'fan' shape, giving you 3D, 4D and even 5D volume all in one application.

Pre-fanned lash extensions add extra length, width, curl and lift to your natural lash line - resulting in an eye-opening effect suitable for all occasions. Experienced technicians should only apply pre-fanned lashes due to the delicate nature of the treatment.

What is 4D silk fibre lash mascara?

4D silk fibre lash mascara is a revolutionary new product that gives you the look of 4D eyelash extensions without committing to semi-permanent treatments. 4D mascara is made from a high-quality blend of natural and synthetic fibres, designed to enhance your existing lashes by adding volume and length.

The silicone brush helps separate and define each lash for an eye-catching finish. Unlike regular mascaras, you can use 4D silk fibre lash mascara multiple times, so you don't have to worry about clumping or smudging throughout the day.

This product is long-lasting but easy enough to remove with warm water, but it’s really an addition, not a replacement for lash extensions.

Who makes 3D and 4D lash extensions?

The eyelash extensions use top-quality synthetic silk fibres for an ultra-soft finish that won't irritate the eyes or cause any damage to your natural lashes.

To summarise, 3D and 4D lash extensions offer dramatic looks for special occasions or if you want something bolder than traditional 1:1 lashes. Hybrid lashes combine 3D/4D and 1:1, while 4D silk fibre mascara is an easy way to get the look of 4D lash extensions without commitment.
