This is not my problem but just found this info. I do take hydrochloric acid with pepsin daily for good measure.

Here is a short article about what Dr. Jonathan Wright had to say about the connection between Rosacea and little or no stomach acid. So for people who have digestion problems and don’t know why, sometimes it is LOW STOMACH ACID PRODUCTION, so taking an Antacid is the worst way to get relief.

Dr. Wright talks about rosacea and the use of betaine hydrochloride.

It’s sad that information about the very common connection between acne rosacea and low stomach acid has been lost. In 1948, an article about rosacea in a major medical journal stated that “every dermatologist knows” about this connection. In 2009, hardly any dermatologists know about it!
