Glowing text is perfect for sci-fi titles, neon looks, or anything that needs extra punch and visual impact.
Steps to make glowing text
Create your text, then go to Effect → Stylize → Glow.

Increase Glow Radius to soften the halo and adjust Glow Intensity to control brightness.

Duplicate the glow effect and use different Threshold and Radius values to layer a soft outer glow with a tighter inner glow. Two glows always look better than one.

One more thing
Switch your project to 32 bits per channel (float) for smoother, more realistic glows. In the Project panel, click the 8bpc/16bpc toggle at the bottom and set it to 32 bpc. The extra color data lets the glow effect blend more naturally without harsh banding.
