About This Treatment
This set was done by Mami at lull. in Harajuku. The menu was Accent Design (up to 6 nails), with the existing gel removed and rebuilt using the fill-in method rather than a full soak-off. The client was visiting from the United States, and the work was done on her natural nails without extensions.
Design Highlights
The structure of this set comes from the fill-in. Instead of taking everything back to the bare nail, only the lifted and grown-out portion was removed, the base was refined, and new product was added to rebuild an even apex. That keeps the surface flat and the sidewalls clean, which matters when art is going on top.
From there, accent points were placed across six nails, leaving the remaining nails as the quieter base. Spreading the art over six rather than one or two lets the design read as a set from a distance, while each hand still has calm nails to balance it. The finish was kept thin through the free edge so the nails don’t feel bulky.
A Note from the Visit
The client is a nail artist herself, and runs her own salon. She told us she attended nail school for a short period and built up most of her skill self-taught from there. Sitting in the client’s chair for once, she watched the fill-in process closely and looked genuinely pleased with how the accent nails came together.
Guests who work in the industry tend to notice different things — cuticle work, apex placement, how the product sits at the sidewall — and that makes for a good conversation during the appointment.
Care and Styling Notes
A few practical points about this kind of set:
- Fill-in vs. full off. A fill-in removes only the grown-out and lifted product, keeping the healthy base layer in place. It reduces repeated filing on the natural nail and usually keeps the appointment shorter. It works best when the existing gel is in good condition with no widespread lifting.
- Timing. Most people come back for a fill-in around the 3–4 week mark. Waiting much longer lets the regrowth line get deep, which makes rebuilding the apex harder and can lead to lifting at the stress point.
- Daily care. Cuticle oil once or twice a day keeps the sidewalls flexible and helps the seal last. Gloves for dishwashing and cleaning are the single biggest factor in avoiding early lifting.
- Who accent designs suit. If you want art but still need your hands to look appropriate at work, placing design on a limited number of nails is an easy middle ground. It also keeps the cost down compared with a full set of art, and it’s a good option for travellers who want something memorable from Tokyo without committing to something loud.
Comment from Mami
Fill-ins are the part of the job I find most satisfying, because almost nothing about the result is decorative. You’re judging how much old product to take down, where the apex needs to sit, and whether the new layer will blend invisibly into the old one. Get that wrong and the art on top never looks right, no matter how neatly it’s painted.
Working on another nail artist’s hands is its own kind of appointment — she knew exactly what she was looking at, and I enjoyed that. Thank you for choosing lull. while you were in Tokyo.
