Exfoliating Toner
Exfoliating Toner — a liquid formula applied after cleansing that uses chemical exfoliants such as AHAs, BHAs, or PHAs to loosen and remove dead surface skin cells. It is designed to smooth texture, brighten dull skin, and support the penetration of subsequent products, and is typically used a few times per week rather than daily.
Key points
- Common active ingredients include glycolic and lactic acid (AHAs), salicylic acid (BHA), and gentler gluconolactone (PHA).
- Unlike physical scrubs, it exfoliates chemically by dissolving the bonds between dead skin cells rather than abrading the surface.
- Frequency should be built up gradually, and overuse can compromise the skin barrier and cause irritation or sensitivity.
- Chemical exfoliants can increase sun sensitivity, so daily broad-spectrum sunscreen is generally recommended during use.
Frequently asked
How often should I use an exfoliating toner?
Most people start with one to three times per week and adjust based on how their skin responds, since tolerance varies by ingredient and concentration. Daily use is usually only appropriate for very gentle formulas and resilient skin.
Can I use an exfoliating toner with a retinoid?
Combining acids and retinoids can increase the risk of irritation for some people, so many prefer to alternate them on different nights. Introduce one active at a time and observe how your skin tolerates it.
