Introfill
(Water Glow Injection)
What is Introfill (Water Glow Injection)?



Water Glow Injection is a treatment that uses a device with ultra-fine needles to deliver various cosmetic ingredients into the skin.
It involves minimal pain and downtime, and makeup can be applied from the same day.
Our clinic uses two types of Water Glow Injection devices: Introfill and Hycoox.
You can upgrade from Introfill to Hycoox by paying an additional fee on top of the standard Water Glow Injection price:
・Up to half face: +¥3,300
・Full face (or scalp and above): +¥5,500
Treatment Areas
- Neck and hand wrinkles
- Wrinkles on the neck and hands are often more noticeable than expected.
By broadly and superficially injecting wrinkle-improving ingredients and hyaluronic acid, the appearance of wrinkles can be improved.
- Pore treatment and skin quality improvement
- Botulinum toxin and skin-enhancing ingredients are blended and injected.
By widely administering the treatment to areas with visible pores, it helps suppress pore activity, making pores appear smaller and tighter.
Because the injections are delivered into the superficial layer using an ultra-fine special needle, pain and downtime are minimal. Excess oiliness and shine can also be improved.
- Hair growth treatment
- Using Water Glow Injection, medicinal hair-growth ingredients such as minoxidil and peptide-based nutrients are directly delivered into the scalp.
There is very little pain or downtime, and shampooing is allowed from the same day. This treatment is also recommended for men.
