![]() It’s not like it’s preventing it from getting into your skin at all. The most it may do is slow absorption of the niacinamide. If the pH 2 solution was kept at 30 ☌ (86 ☏) we could expect it to take over 4800 hours or almost half a year – and that’s if the acidic solution didn’t corrode your skin first!” Heat vastly speeds up reactions a rough approximation is that every 10 ☌ (18 ☏) increase in temperature doubles the reaction rate. In another experiment it took about 75 hours in a pH 2 solution at 90 ☌ (194 ☏) to convert about half the niacinamide to niacin. “In fact, niacinamide is so stable, that a 10% solution can be heated to 120 ☌ (248 ☏) for 20 minutes with no niacin forming. They probably know more about this than you or I do. ![]() So unless you have rosacea or some other form of hypersensitivity, this is probably a moot point. The conversion process is extremely slow you’re most likely not getting an appreciable dose of niacin even in a product formulated with an acidic ph the product would likely be expired before that happens.
