HA Skin Booster FAQ
How is the HA skin booster different from Skin Botox?
The HA skin booster uses hyaluronic acid to restore hydration and glow beneath the skin's surface, while Skin Botox focuses on refining skin texture by reducing pores, oil and fine lines. If dehydrated, dull skin is your concern, the HA skin booster is considered; if enlarged pores and fine lines are your concern, Skin Botox is considered, and the two are sometimes combined.
