How Does Acne-Ltd Work?

How does Acne Ltd work in the treatment of acne? The Four Mechanisms of Action by which the primary ACNE LTD III ingredients of sulfur and zinc work are as follows:

(1) Acne Ltd is anti-inflammatory, thereby reducing redness (better than antibiotics which your body becomes immune to after 3-5 months).

(2) Acne Ltd is a vascular constrictor, so it reduces the size of the capillaries that cause redness and blushing (on which antibiotics have never had an effect).

(3) Acne Ltd dehydrates bacterial cells.

(4) Acne Ltd has a pH of approximately 7 (neutral). Many oral and topical treatments for acne are very acidic, which often makes for a continual problem for many acne sufferers and especially so in pregnancy and breast feeding.
