Objectives: 1. To improve skin texture, dermal hydration and fine wrinkles
intradermal injection (using polydensfied monophasic HA and Incobotulinum toxin ) was used in this article.
2. To inject into the dermis, the special designed automatic injector was used. (The manual injection is not easy and tiresome for intradermal injection into 1000 sites.)
3. When using polydensfied monophasic HA during intradermal injection, the risk of making dermal lumps can be reduced. Also, the management of dermal lumps can be easier.

Introduction: Skin texture is an essential factor for beauty and anti-aging. The subdermal injection cannot make satisfied improvement of skin texture and fine wrinkles. Stabilized hyaluronic acid (S-HA) filler gels have been mainly used to treat folds. Many injectable fillers are used to treat by volumization into the subdermal layer. But I prefer to treat skin texture also. Therefore I started to use intradermal injection using S-HA for improving skin texture. To prevent making lumps, I prefer Monophasic-polydensidfied-HA and using the injector.
Materials / method: The automatic injector with 9-needle and the negative suction system was used to inject tiny amount such as 1 micro-liter per site. Using injector was better than the manual way to reduce the injection amount per injection site and to reduce making lumps.
I made 3cc of a mixture of injection material for a face with 1cc of S-HA, 40U of Inco-botulinum Toxin (1cc), 0.5cc N/S and 0.5cc of lidocaine. Injection depth was 1mm. I made 1000 injection sites with 100 passes using 9-needle-head.
Skin texture, dermal hydration were evaluated. Biopsy was obtained with H&E, Trichrome stains.
Results: There was a dramatic improvement of fine wrinkles on face after intradermal injection of mixture solution made by S-HA and Incobotulinum Toxin. Dermal hydration using S-HA made well-hydrated skin for patients with less dryness feeling after washing face. Skin after injection became shiny. Hydration effects and improvement of fine wrinkles lasted more than 6 months. And most patients wanted 2nd injection after 6 months.
Conclusion: There are unique effects after intradermal injection of mixture solution (S-HA and Botulinum Toxin). “Skin-Botox” using Incobotulinum (not a medical term) and dermal hydration using S-HA can treat fine wrinkles and improve skin texture on faces with a natural expression. There is a synergic effect when skin-toxin is combined with dermal hydration with S-HA.
