Yeah, 30 is the darkest color. I would guess that 30 or 20 would work for you. It’s hard to say which one is the better concealer. I find that Biotherm’s thinner formula is easier and quicker to work with when I’m in a hurry/lazy. It has more staying power too, especially when it’s hot and humid. Although Select Cover has heavier coverage, you get a lot of bang for your buck with Biotherm ’cause you don’t have to use a lot of it because it’s so highly pigmented. Try it! And lemme know whatcha think …
