Sunday Riley - Saturn Sulfur Spot Treatment Mask

It snells bad, but it works

This treatment somehow transforms my whiteheads into deep cystic acne, which I am not typically prone to. The smell is absolutely ghastly and the result is a horrendously painful blind pimple. You could not pay me to use this product again.

Although it works well, this mask is only 0.5oz but still so pricey. I would repurchase if on sale though.
