I've been using Bio-Soothing Cream since a facialist recommended it to me.. I use it when I get a deep mountainous zit on my chin - the ones that never come to the surface. I take a tiny amount of cream and really rub it into the zit at night. Normally the zit is smaller by morning. You can also apply during the day but since it's green you'll need to tissue any extra off.
The cream has a weird thick, oily, grainy texture, but don't let that turn you off. I like to think the grains help exfoliate the skin, letting the product absorb as I rub it in.
Also, the tub is really tiny, but since you don't use much, it lasts me about 5 years, at which point it's still half full but I feel like I should replace it.
