31 May 2026 10 min read 839 views 0
Lactic acid's larger molecular size makes it gentler than glycolic acid, and its natural humectant properties suit sensitive, dry or reactive skin.
Key takeaways
- Lactic acid's larger molecular size means gentler, shallower penetration than glycolic acid.
- It has a genuine humectant, hydrating property in addition to exfoliating, unusual among AHAs.
- Typical concentrations for regular use range from 5 to 10 percent.
- It is widely recommended as a starting point for people new to acids or with sensitive, reactive skin.
