The short answer
GABA can be a reasonable part of an aging-well routine if you tolerate the formula and use it consistently.
The goal here is long-term skin health, not a quick cosmetic reset.

Is GABA good for aging skin?
A neutral, maintenance-first look at GABA: what it can do, what it can’t, and how to use it long-term.
What it can realistically support
Temporarily relaxes micro-musculature in the skin, reducing the appearance of fine lines
May reduce wrinkle depth with consistent use (studies show temporary improvement)
Provides some hydration and barrier-support benefits
When to be cautious
Limited long-term topical data: treat as an emerging ingredient
Effects are temporary (muscle-relaxation-like smoothing wears off)
If you want only well-established actives, GABA is optional
If you’re currently irritated or peeling, stabilize your barrier first and introduce one change at a time.
How to use it in a maintenance routine
PM: typically used as a serum step before moisturizer
Can be used AM for temporary smoothing effect under makeup
Give it a few weeks of consistent use to assess whether you notice a difference
