When my skin starts feeling congested I can count on this gel to draw out the impurities. Don't start the day before a big event. I work up to full strength by putting a small drop on my toner soaked cotton pad. That way my whole face gets just a tiny bit. Work up to full strength slowly for a slow - not so noticeable purge. I also dot it straight on any bumps at night and then exfoliate the next day.

I have used this product off and on for several years, and I love it. It has a high concentration of glycolic acid without a bunch of other ingredients. It's scent free and very light textured. I just dab it on trouble spots or apply a thin film when it seems like my face could use brightening up. I don't find it drying, like other acid exfoliators can be, but it's also not greasy. And most important, it work wonders-- cuts down on my acne, prevents ingrown chin hairs, and over time it helped me resolve some persistent blemishes that would have required a dermatologist to surgically remove: milia, white heads, little cysts, on my face, shoulders, and even legs.
