Precision Japanese Facial Roller

A compact facial beauty roller from Japan, designed to make your everyday beauty ritual simple.

TERA ROLLER ai II features three independently rotating rollers that glide naturally along the contours of the face — especially around smaller areas like the eyes, nose, cheeks, forehead, and jawline.

No batteries. No charging. No facial oil required.

Use it during your skincare routine, gently over makeup, or whenever you want a quick beauty refresh.

Made in Japan.

Why You'll Love TERA ROLLER ai II

3 Independently Rotating Rollers

Each roller moves independently, helping the tool follow the natural contours of your face.

Compact & Precise

The smaller roller head makes it especially easy to use around the eyes, nose, cheeks, forehead, and jawline.

Warm or Cool

Use it cool for a refreshing morning ritual or gently warmed for a relaxing evening massage.

No Oil Required

Use it on clean skin, after serum, or gently over makeup.

No Charging

No batteries. No electricity. Just pick it up and roll.

Take It Anywhere

Compact enough to keep beside your skincare or carry in your bag.

A Beauty Ritual Loved in Japan

TERA ROLLER has been used by more than 200,000 women in Japan as part of their beauty routines.*

It has also been featured in Japanese beauty media, including beauty and lifestyle magazines in Japan.

SAKEGLOW selected TERA ROLLER because it represents what we love about Japanese beauty:

simple, thoughtful, beautifully made, and easy to enjoy every day.

*Based on cumulative use figures reported by the brand in Japan.

What Makes ai II Different?

Many beauty rollers use one or two larger rolling surfaces.

TERA ROLLER ai II uses three compact, independently rotating rollers, designed for more precise facial use.

The faceted rollers create a light, distinctive rolling sensation while moving smoothly along the contours of the face.

That makes ai II especially easy to use around smaller areas where a larger beauty tool can feel harder to control.

Warm or Cool

One Roller. Two Rituals.

COOL — Refresh

Place the roller head in cold or ice water for approximately 3–5 seconds.

Use gently across the face for a fresh, cooling sensation.

I especially love using it cool in the morning and around the eye area.

WARM — Relax

Place the roller head in warm water at approximately 50°C / 122°F for about 3–5 seconds.

Always test the temperature on your hand before using it on your face.

The gentle warmth creates a comforting, spa-like ritual that is perfect for the evening.

A Simple 3-Minute Ritual

You do not need a complicated technique.

Use light, comfortable pressure and gently roll for approximately 3 minutes.

Forehead
Roll upward toward the hairline and outward toward the temples.

Eye Area
Use very light pressure and glide gently outward.

Cheeks
Roll from the center of the face outward.

Jawline
Glide gently toward the ears.

Neck
Roll gently downward toward the collarbone.

Hairline
Roll gently toward the temples.
