Sulpho-Lac is used to treat common skin conditions including acne vulgaris, rosacea, and seborrheic dermatitis. It may also be prescribed for other dermatological conditions as determined by a healthcare provider.
The exact mechanism is not fully specified, but sulfur-based topical agents work through keratolytic properties that help remove dead skin cells and antibacterial effects that reduce acne-causing bacteria. The lactic acid component may provide additional exfoliating benefits.
Sulpho-Lac is for external use only and should not be ingested. Common side effects may include skin dryness, redness, or irritation at the application site.
