Kate Somerville makes my favorite acne spot treatment with 10% sulfur. This is a quick spot treatment that shows results quickly. I simply use a q-tip to apply the pink liquid on my skin. It hardens and the spot starts to reduce. It can stain so allow time for it dry!
At $26.99 for an ounce, some might find it priced high. I have bought this on sale at @ultabeauty and @nordstrom. The bottle lasts a long time. Mario Badescu makes a similar, less expensive product that doesn’t work for my skin (it deserves its own review). I only purchase the Kate Somerville version.
I can’t give this 5 stars because it is pink. The pink color makes it pop out of my melanin rich skin. Not a bad thing, but I prefer not to wear this product in public. It is either an bedtime or at home treatment. I also have experienced staining from the treatment.
