Good Genes Lactic Acid Treatment — Reddit Reviews
by Sunday Riley
Updated October 10, 2026
Lactic acid exfoliant that smooths texture and boosts overnight glow; pricey.
What the community says
A lactic acid exfoliating serum that people use a few nights a week for smoother texture and a brighter look by morning. It suits dry or sensitive skin better than harsher acids. Stack it with retinoids and some people get irritated.
What this means for you
What people love
- Lactic acid that actually smooths rough texture
- Gives next-morning glow and softer-looking lines
- Surprisingly doable for sensitive skin
Watch out for
- Price tag is brutal for a leave-on acid
- Too frequent use can turn into irritation or breakouts
- Doesn't play nicely with retinoids the same night
