Dear, This reaction is normal. The niacin component in the product dilates subcutaneous capillaries, improving blood supply to the skin and cells. This may cause a temporary feeling of warmth or redness in the skin due to increased blood flow. Typically occurs 15–30 minutes after intake, presenting as facial warmth, redness, itching, or tingling (particularly in the upper half of the face). This is a normal physiological response and usually resolves naturally.With continued use over time, circulation efficiency in the body may improve.
This is a normal reaction to niacin. Drinking plenty of water will help alleviate it.
