Antimicrobial and abrasive products
Chlorhexidine
Chlorhexidine is the only antimicrobial marketed for OTC sale for acne. Two presentations are available: a 1 per cent skin wash and a 2.5 per cent gel.
Abrasive
A single product is available, containing fused synthetic aluminium oxide particles in a soap-detergent base skin wash. The formulation is intended to mechanically remove follicular plugs.
The product is contraindicated in the presence of superficial venules or capillaries (telangiectasia), and overenthusiastic use can cause irritation.
