The Complete Overview of How to Put Lashes on Underneath
The process of applying false lashes underneath the natural lash line is a blend of artistry and technical skill. Unlike upper lashes, which can be placed with a broader margin for error, underlashes require meticulous attention to the curvature of the lower lash line and the eye’s natural contours. The first critical decision is choosing the right lash style: wispy, natural-looking lashes for a subtle enhancement or bold, voluminous strips for a dramatic effect. Each type demands a different approach to adhesive application and placement angle, and selecting the wrong style can result in lashes that look unnatural or even comical. Equally important is the adhesive itself. Traditional lash glues can be too heavy for the delicate skin beneath the eyes, leading to irritation or lashes that lift prematurely. Modern alternatives, such as hypoallergenic, quick-dry adhesives, are designed specifically for underlash application, offering a balance of hold and comfort. The adhesive must be applied in a thin, even line—never too much, which can cause lashes to clump, nor too little, which risks detachment. This precision is what separates a temporary, at-home application from a salon-quality finish that lasts all day.Historical Background and Evolution
The concept of enhancing the eyes with false lashes dates back to ancient civilizations, where women in Mesopotamia and Egypt used kohl and other pigments to darken their lashes and eyelids. However, the modern false lash as we know it emerged in the early 20th century, popularized by Hollywood stars like Marilyn Monroe and Audrey Hepburn, who used them to create iconic, sultry looks. Initially, lashes were applied only to the upper lash line, as the lower lash line was considered less critical to the overall aesthetic. It wasn’t until the 1980s and 1990s, with the rise of avant-garde makeup artists like Kevyn Aucoin, that underlashes became a staple in high-fashion and editorial makeup. Today, the technique has evolved into a sophisticated art form, with lash artists developing specialized tools and adhesives tailored for underlash application. The shift toward individual lashes (rather than strips) has also democratized the process, allowing for more customization and a more natural finish. Brands now offer hypoallergenic, waterproof, and even magnetic lashes designed specifically for the lower lash line, catering to both professional makeup artists and beauty enthusiasts looking to achieve a salon-worthy look at home.Core Mechanisms: How It Works
The science behind how to put lashes on underneath lies in three key factors: lash structure, adhesive chemistry, and the mechanics of placement. The lower lash line is shorter and less dense than the upper lash line, meaning the lashes must be applied in a way that mimics the natural curve without overpowering it. Adhesives designed for underlashes are formulated to bond quickly yet gently, avoiding the irritation that can occur with heavier glues. The best adhesives contain ingredients like cyanoacrylate, which creates a strong yet flexible bond, and humectants to prevent drying out the delicate skin beneath. The placement angle is perhaps the most critical element. Unlike upper lashes, which are applied in a straight line, underlashes must follow the natural curvature of the lower lash line, which is typically more pronounced at the outer corner of the eye. A common mistake is applying lashes too close to the lash line, which can cause them to lift or appear unnatural. Instead, they should be placed just beneath the natural lashes, with a slight upward angle to follow the eye’s contour. This technique not only enhances the eye shape but also prevents the lashes from digging into the skin, reducing the risk of irritation.Key Benefits and Crucial Impact
The decision to apply lashes underneath is more than just a cosmetic choice—it’s a strategic enhancement that can alter the perception of eye shape, brightness, and overall facial harmony. For those with naturally sparse lower lashes, underlashes can create the illusion of fuller, more defined eyes, while those with hooded eyelids can use them to lift the lash line and draw attention to the eye’s shape. The psychological impact is equally significant; well-placed underlashes can make the eyes appear more awake and expressive, a subtle but powerful effect in both personal and professional settings. Beyond aesthetics, the technique offers practical benefits, particularly for those who struggle with lash growth or loss due to aging, medical treatments, or genetic factors. Underlashes provide an instant solution without the need for invasive procedures like extensions, making them a popular choice for individuals seeking a low-maintenance yet high-impact beauty upgrade. The ability to customize lash length, curl, and density also means the technique can be adapted to suit any eye shape or personal style preference.*"The lower lash line is the unsung hero of the eye—it frames the gaze and adds depth. When applied correctly, underlashes don’t just enhance; they redefine the look."* — **Kevyn Aucoin, Legendary Makeup Artist**
Major Advantages

Future Trends and Innovations
The future of underlash application is poised to be shaped by advancements in adhesive technology and lash design. Currently, the industry is moving toward magnetic lashes, which eliminate the need for adhesives entirely, reducing irritation and making removal effortless. These lashes are held in place by tiny magnets embedded in the strip, allowing for a secure yet gentle application that can be reapplied multiple times without damaging the natural lashes. Additionally, the rise of AI-driven makeup tools may soon offer personalized lash placement recommendations based on individual eye shapes and preferences, further democratizing the technique. Another emerging trend is the development of "smart lashes"—lashes infused with skincare benefits, such as hyaluronic acid or peptides, to nourish the delicate skin beneath while providing enhancement. Brands are also experimenting with biodegradable materials for lashes and adhesives, catering to eco-conscious consumers who want to minimize their beauty footprint. As the demand for underlashes grows, particularly in the K-beauty and J-beauty markets, we can expect to see more innovations in lash textures, from ultra-realistic individual lashes to bold, artistic designs that push the boundaries of conventional beauty standards.
Conclusion
Mastering how to put lashes on underneath is about more than just following a set of instructions—it’s about understanding the interplay between lash structure, adhesive science, and personal aesthetics.

The art of placing lashes underneath isn’t just about beauty; it’s about confidence, precision, and the ability to transform a simple beauty ritual into a masterpiece.Comprehensive FAQs
Q: Can I use the same adhesive for upper and underlashes?
No. Upper lash adhesives are often thicker and may contain ingredients that can irritate the delicate skin beneath the eyes. Always use a hypoallergenic, quick-dry adhesive specifically formulated for underlashes to minimize discomfort and ensure a secure hold.
Q: How do I prevent underlashes from lifting or curling up?
To avoid lifting, apply lashes as close to the natural lash line as possible without touching it, and use a thin line of adhesive. Press firmly for 3–5 seconds to allow the adhesive to bond fully. Additionally, avoid rubbing your eyes or using oil-based products immediately after application, as these can weaken the adhesive.
Q: Are individual lashes better than strips for underlash application?
Individual lashes offer more customization and a more natural look, making them ideal for underlash application. Strips can be bulkier and may not conform as well to the lower lash line’s curvature. However, if you prefer strips, opt for shorter, wispy styles that mimic natural lashes.
Q: How long do underlashes typically last?
With proper application and care, underlashes can last 6–12 hours, depending on the adhesive and environmental factors like humidity. To extend wear time, avoid steam (such as from hot showers) and use a lash primer designed for underlashes to enhance adhesion.
Q: Can I apply underlashes if I have sensitive skin?
Yes, but with caution. Choose a hypoallergenic adhesive and perform a patch test 24 hours before application. If you experience redness or irritation, discontinue use and consult a dermatologist. Some brands offer fragrance-free and steroid-free adhesives specifically for sensitive skin.
Q: What’s the best way to remove underlashes without damaging my natural lashes?
Use a gentle lash remover or micellar water to dissolve the adhesive, then carefully lift the lashes with tweezers or a lash brush. Avoid rubbing, as this can tug on natural lashes. Never pull lashes off by the roots, as this can cause thinning or loss.
Q: Can I apply underlashes over mascara?
No. Mascara can interfere with adhesive bonding and may cause lashes to clump or lift prematurely. Always apply underlashes before mascara, and use a hypoallergenic adhesive to avoid reactions.
Q: How do I choose the right lash curl for my eye shape?
The curl should complement your natural lash line. For round eyes, a slight curl (B or C) enhances definition. Almond-shaped eyes can handle a medium curl (D or E), while hooded eyes benefit from a softer curl (A or B) to avoid digging into the skin.
Q: Are there any makeup artists’ secrets for a flawless underlash application?
Professionals recommend using a lash comb to align lashes before pressing them down, and they often apply a tiny dot of adhesive at the outer corner to secure the lash strip more effectively. Additionally, they suggest using a clear brow gel to set the lashes and prevent smudging.
