I think this is a good mask to have on hand for when your skin needs a little perking up, but nothing extreme. I tend to travel with either this or the Get Your Glow On mask from the same brand, as they're both the type of no nosense masks that are great for when you've only got a few minutes to spare. Deep Down Detox mask is a quick drying, creamy kaolin mask that doesn't dry completely stiff like many other clay masks do. It's not too abrasive either, despite the name. Perhaps that's thanks to a few soothing ingredients, apart from kaolin, like aloe and cucumber. There's a pleasant scent of orange (it contains bergamot and orange oil, but also perfume) that lingers while using the mask, without being overbearing. When washed off, my skin feels smooth and well cleansed, but not overly tight the way it sometimes does after using similar masks. It's a pleasant mask to use, but it's not a miracle worker. If you've tried other masks from Formula - I'd say this is way less abrasive and more pleasant to use than the aggressive Pores Be Pure mask, but less effective than the Get Your Glow On mask when it comes to visible results.
+ Cruelty free
+ Great price point
+ Cleanses without drying out
+ Generally not harsh (but maybe not suitable for super sensitive skin either)
+ The packaging, like all Formula's products, brightens up my bathroom shelves
- Has parabens
- The results are quite short-lived
