I have used a couple of glycolic peels from other retailers and I am happy to report that this one is the best one so far. The dropper style bottle is a good idea for reducing waste, the green glass bottle is so cute you want to have it out on your dressing table. The strength of the formula seems to be fairly gentle, so you can use it more than once a week, no severe redness or obvious flaking afterwards, but it almost instantly calms down the dark patches left by acne, and after a couple of uses fades them considerably. I will need to continue using to work out its longer-term results on pores, but for now, based on my initial uses, I am extremely happy!
