Loreal True Match is pretty pale (not quite pale enough for me, but close). I won't repurchase though because it clings to dry spots. If you ever get a little dry or flaky it will drive you nuts. It's a liquid-to-powder formula...kind of a like a two-in-one shampoo and conditioner, it tries to be a liquid that dries to a powder finish....I just find it doesn't work well.
What a lot of makeup artists do is combine this mixing foundation (which is a pure white) with your favorite formula that's too dark. You use however much white you need to lighten it up. The formula mixes smoothly and then you don't have to sacrifice a foundation that feels great for one that feels crappy but is the right color.
If that's too much experimentation for you, the NYX HD in Nude is quite pale.
Licorice root INCREASES net cortisol (by reducing the level at which it is broken down). Cortisol weakens the immune system. It basically shuts down the immune system in response to stress--think fight or flight, if you're fighting for your life, your body needs to focus on the task at hand, and diverts energy from immune system tasks to the stress response.
Since acne is partially an immune response, shutting down your immune system means that your skin stops reacting. It doesn't really stop the cause of the acne but it can stop the end part of the response.
Whether that's a good idea or not depends on if you were low in cortisol in the first place. If you were not low in cortisol before licorice root, then increasing it could cause long term damage. The research I've read indicates that most people in the modern world are too high in cortisol, not too low.
If you are already experiencing noticeable side effects from Accutane beyond a little extra dryness and chapped lips, I don't think there is anything you can reasonably do to "counter" the damage that Accutane is doing. Accutane either works wonderfully with little to no damage, or it wreaks havoc. I don't know why this is but I see it happen over and over.
If I were in your position I would get off of Accutane immediately and put my hope in a different cure.
