Alright, I did some testing in the Practice Tool.

1) Iron Skin activates almost immediately, and lasts only 3 seconds (It does not continuously refresh over the potion duration).

2) You cannot stack multiple potions, activating a Health Potion and a Biscut at the same time will only grant you a +5% armor increase once, and only for 3 seconds.

3) You CAN activate multiple potions in a row. For each potion you activate, the duration of Iron Skin refreshes, but does not stack.

4) Iron Skin applies to all Potions, and the Biscut from the Inspiration tree. However, it does not apply to any of the consumables from the Kleptomancy Rune. Additionally:

5) Iron Skin applies to: Face of the Mountain, Locket, Steraks Gage, Maw, Gunblade, and Champion healing and shielding abilities.

6) Iron Skin does NOT apply to: Redemption, Stoneplate, Edge of Night, Zhonyas, Warmogs or other passive healing.

7) A very interesting interaction I found was that Iron Skin applies every time you activate a Hunters Potion. Iron Skin may be at its most effective in the jungle, where the bonus 5 armor will reduce the damage you take from neutral monsters and you can continously reapply the bonus armor every time you use a potion (which is often as you are fighing neutral monsters). Then, your potion refills every time you kill a jungle camp.

Additionally, it may be valuable in bot lane if you are on a weaker early champ and you have someone like Soraka supporting you. However, this is a small benefit and not worth taking bot lane on this merit alone.
