Chlorhexidine Digluconate
Ingredient Info
Chlorhexidine digluconate is an antimicrobial agent that kills bacteria and fungi on the skin. It's commonly used in rinse-off products like cleansers and mouthwashes, and occasionally in leave-on skincare formulations to help prevent infection and reduce microbial growth.
Benefits
- Effective antimicrobial action against a broad range of bacteria and fungi
- Can help reduce biofilm formation, making it useful for persistent skin infections
- Well-established safety record in medical and dental applications
Potential concerns
- Contact dermatitis and allergic sensitization possible in some individuals, particularly with prolonged or repeated skin contact
- Can cause skin irritation, staining, or discoloration with extended use on intact skin
- Not recommended for frequent use on healthy skin due to potential disruption of beneficial skin microbiota
- Should be used in rinse-off rather than leave-on formats for facial skincare to minimize irritation risk
Science: Chlorhexidine digluconate demonstrates strong antimicrobial efficacy against pathogenic organisms including Candida albicans, and is particularly effective at disrupting established biofilms. However, contact dermatitis studies show a notable sensitization rate in patch testing, indicating allergic potential in susceptible populations.
