According to the samprapti of acne, which factor contributes to skin inflammation?

• A. Ranjaka P from blood goes into skin creating inflammation, irritation, and fatty acid secretion.
• B. Excess caffeine intake
• C. Cold exposure reduces inflammation
• D. Direct bacterial infection from environment

Answer: (A)

In acne’s samprapti, inflammation starts when Ranjaka Pitta, a refined form of Pitta associated with blood, migrates from the bloodstream into the skin. This vitiation of Pitta in the skin creates heat and irritation, which then stimulates the sebaceous glands to secrete more fatty acids. The combination of inflamed skin and increased fatty acid secretion promotes the oily, irritated environment that characterizes acne lesions and sets the stage for blockage and further inflammatory responses.

Other options don’t fit this initiating mechanism: lifestyle factors like excess caffeine may influence symptoms but do not originate the inflammatory process in this framework; cold exposure is generally anti-inflammatory in this context rather than the primary cause; and direct bacterial infection from the environment is not the initiating samprapti event—bacteria often play a role after the inflammatory milieu is established.
