Soft, customized lash extensions applied with UV lash technology for clean definition, comfortable wear, and a polished everyday finish. Every set is mapped to your eyes at our two Tucson studios.
Each appointment opens with lash mapping to design length, curl, and fullness around your eye shape and natural lashes.
Our UV light-cured adhesive bonds on contact for a secure, even set, with a tailored fill schedule to keep your lashes looking their best.
Every lash set at Sonthuy is applied with UV lash technology. It's a deliberate choice that shapes how calm, clean, and unhurried your appointment feels, from the first lash to the moment you leave.
The technology supports a careful, controlled process, so each extension can be placed with attention and accuracy.
A pass of UV light sets the light-cured adhesive during your appointment, rather than waiting for it to air-dry over time.
Because the set bonds as it's applied, you spend less of your day waiting for adhesive to settle before you head out.
It's one of the intentional details that make a Sonthuy lash appointment feel considered, refined, and unhurried.
Both are professional approaches, the difference is in how the adhesive sets. At Sonthuy, we apply UV lash extensions exclusively.
Every style below, Classic, Hybrid, Volume, Mega Volume, Design, and Bottom Lashes, is an option within UV Lash Extensions, not a different service. Each set begins with lash mapping, so length, curl, and fullness are designed around your eye shape and natural lashes.
A single extension on each natural lash for clean, mascara-like definition that still looks like your own lashes.
Best for natural fullness with textureA balanced blend of single lashes and handmade fans, adding gentle density and texture while staying soft and wearable.
Best for full, lush coverageMultiple lightweight handmade fans per lash for richer fullness, a soft, luxe density rather than a heavy or harsh finish.
Best for maximum, lush fullnessLarge, ultra-fine fans layered for the fullest look, still lightweight and mapped to stay comfortable and wearable.
Best for a custom, artistic lookA bespoke set blending lengths, curls, and textures, designed with your artist for an expressive, one-of-a-kind finish.
Best for added definition for the lower lash lineFine, lightweight extensions on the lower lashes to balance an upper set or soften the eyes, applied with the same careful mapping.
Fills shown are priced every 2 – 3 weeks (Bottom Lashes every 1 – 2 weeks) — see each style's page for the full fill-pricing table by week. A Master Lash Technician upgrade is available on any style for a refined finish, ask at booking.
UV lash extensions suit anyone who wants softer, fuller-looking lashes without daily mascara, whether you're after barely-there definition or fuller volume. They're a thoughtful choice for busy mornings, special occasions, or simply waking up ready.
If your natural lashes are very fine or your eyes are sensitive, that's worth sharing at your consultation, we'll map a set that's comfortable and wearable for you, and tell you honestly if a lighter style suits you better.
For the first 24 to 48 hours, keep lashes dry and avoid steam so the bonds settle fully. After that, a gentle daily brush with a clean spoolie keeps them looking neat.
Avoid oil-based products and waterproof mascara around the eyes, and book a fill every two to three weeks as your natural lashes cycle. How long a set lasts varies with your lash growth, aftercare, and lifestyle.
Real UV Lash Extension reviews from our Tucson clients.
I have had lash extensions on and off for close to a decade and always stopped because of inconsistent fills or irritation. I have had none of those issues since giving Son Thuy a try this summer, and I have loved having full, long lashes. The studio is lovely and everyone is very kind and helpful. Definitely recommend.
From the moment I walked in, the atmosphere was welcoming and professional, and the lash technicians were skilled and attentive to detail. The special glue and light technology make the extensions waterproof and long-lasting. The result was stunning, natural yet glamorous, and included a back and shoulder massage. I highly recommend them.
My lashes look amazing. Beautiful work, great attention to detail, and a wonderful experience from start to finish. I could not be happier with the results.
Best experience ever. I have been coming here for six months for my lash extensions and have never walked out disappointed; my lashes are always flawless. Everyone was welcoming and professional and helped ease my anxiety. The space is clean and sterile, and you can tell they care about their clients.
My lashes have never lasted as long as they do with this service. The atmosphere is relaxing, prices are affordable, and there are many lash options to choose from. Awesome service with Jasmin.
Jasmine was great; she asked all the right questions and my lash extensions turned out perfect. I showed her a picture of what I wanted and she duplicated it perfectly, checking in throughout. She has a light hand and got my lashes done quickly. I would recommend her to anyone.
Calm, clear answers about comfort, retention, and caring for your UV lash extensions.
UV lash extensions are semi-permanent lashes applied with a UV light-cured adhesive that bonds on contact rather than air-drying, so the set is secure before you leave, with no long dry time afterward.
Yes. Every lash set at our Tucson studios is a UV lash extension, applied with a UV light-cured adhesive. Classic, Hybrid, Volume, Mega Volume, Design, and Bottom Lashes are style options within the service, not separate kinds of lashes.
Applied correctly, one extension isolated per natural lash and weighted to suit it, they shouldn't harm your lashes. Careful mapping, clean isolation, good aftercare, and on-time fills all help keep your natural lashes healthy.
A set wears as your natural lashes grow and shed on their own cycle. How long yours hold varies with your lash growth, aftercare, and lifestyle, so results differ from person to person.
Most clients book a fill every two to three weeks to keep a set looking full as natural lashes cycle. Your artist will suggest the right timing for your lashes.
From Classic for soft, everyday definition to Hybrid, Volume, Mega Volume, custom Design, and Bottom Lashes, every style is part of UV Lash Extensions. If you're unsure, we'll recommend one at your consultation based on your lashes and the look you want.
UV lash extensions are available at both Sonthuy Tucson studios, Brows & Lash on Thornydale and Hair & Skin on Silverbell. Book whichever location is most convenient for you.
Book your UV lash appointment at either Tucson studio, or reach out and we'll help you choose the right style.
