I’m obsessed with the CACI Purifying Silver Mask! As someone with sensitive and acne prone skin who tends to be irritated by a change in weather and the elements, my skin thanked me for using the silver mask. After taking it out of the fridge the cold feeling on my face was incredible. The masks are also so moist with a ton of serum remaining to rub into the skin. After 20 minutes my face looked and felt subtle and soft. The next day my face looked calmer and balanced. I cannot recommend these enough.
