Lactic Acid 5% + HA — Reddit Reviews
by The Ordinary
Updated October 3, 2026
5% lactic acid smooths texture and tackles tret dryness; stingy for some.
What the community says
A 5% lactic acid serum with sodium hyaluronate crosspolymer that many people slot between tret nights or use after showering. It suits dull, bumpy, dehydrated skin, but sensitive or over-exfoliated faces can get red, stingy, or break out.
What this means for you
What people love
Watch out for
- Can sting, redden, or peel when your barrier is already angry
- Some acne-prone skin breaks out or gets rough and bumpy
- Results are inconsistent for texture and PIH
