I'm generally skeptical about face creams, but this one works. I believe I have hormonal acne that suddenly appeared now in my 40s. Noticed a clear effect after just one day, and after about a week, it's almost all gone.
Fun fact: I've noticed that my silver necklace has darkened significantly with use, and it seems that the sulfur in the cream causes silver to oxidize (and turn black). Probably because I was careless with hand washing after application and then touched the necklace. The discoloration does come off with a bit of silver polish.
