Buffered Acid
Buffered Acid — an exfoliating acid formula whose pH has been raised, or buffered, to reduce its harshness while retaining exfoliating activity. Buffering shifts some of the acid into its salt form, lowering the free acid value to create a gentler, more tolerable product.
Key points
- Buffering agents partially neutralize an acid to raise the formula's pH toward a milder range.
- A buffered acid typically has a lower free acid value than an unbuffered version at the same concentration.
- Buffering is often used to make exfoliants more suitable for sensitive or beginner skin.
- The trade-off is that reduced free acid can mean gentler but potentially slower-acting exfoliation.
Frequently asked
Does buffering make an acid less effective?
Buffering reduces the free acid available to exfoliate, so it can make a product gentler and potentially slower-acting, though it also lowers the risk of irritation.
Who benefits most from buffered acids?
People with sensitive skin or those new to chemical exfoliation often find buffered acids more comfortable while still getting gradual exfoliating benefits.
