Glycolic acid's tiny molecular size lets it penetrate skin deeply, making it the most effective but also most irritating common AHA for texture.

Key takeaways

• Glycolic acid has the smallest molecular size of the common AHAs, giving it the deepest penetration and strongest effect.
• Home-use products typically range from 5 to 10 percent, while professional peels use much higher, controlled concentrations.
• Visible texture improvement typically appears within 4 to 8 weeks of consistent, gradually increased use.
• It carries a higher irritation risk than gentler AHAs, so sensitive skin may do better starting with lactic or mandelic acid.
