Good Genes Lactic Acid Treatment — Reddit Reviews
by Sunday Riley
Updated September 24, 2026
Lactic acid exfoliant for smoother, brighter skin; pricey and can sting.
What the community says
A lactic acid treatment that people use a few nights a week for texture, dullness, and next-day glow. It suits skin that wants visible smoothing without the harsher peel vibe. The catch is the price and the fact that stacking it with other acids or retinoids can get irritating fast.
What this means for you
What people love
- Lactic acid glow for rough texture
- Smoother, brighter skin by morning
- Works even on sensitive skin
Watch out for
- Pricey enough to make people ration it
- Can irritate or overdo it with retinoids
- Daily use can trigger purging or breakouts
