I usually apply this on large cystic spots and leave it on for about 15 minutes. It helps to reduce the size of the spots. My skin is a little sensitive so I feel a tingling sensation when it’s applied, but it’s nothing too uncomfortable. 

Yes it’s pricey but it does miracles in mild exfoliation ! 

This is a very powerful mask! I have used it several times but cannot say that it worked wonders on my skin. I was a bit apprehensive because it tingled quite a lot. It did not break me out or irritate my skin but cannot say it was worth the price.

I’ve reviewed this product few of months ago. And now I feel like I have to be fair and give an update. Mask is indeed quite a powerful one. I only use it for T-zone once a week. It no longer breaks me out. It leaves incredibly clean skin, minimized pores, nice glow, helps to avoid congestion. Overall texture of my skin has improved after using this mask consistently. I think I’ll repurchase. It’s a bit pricey like all Tata Harper masks but it lasts long time.

It does clean the pores, but I ended up only using it on my nose because it’s way too harsh for other areas, it strips all the oil (I’m normal to combination skin) and tightens your skin in a way acid peels do. Can dry your skin out and cause peeling. Also like the previous reviewers said it may break you out even though I’m not blemish prone. But this gave me few break outs when I used it all over my face. Don’t use it if you have couperose prone skin, this mask can make it worse. Overall it’s a questionable product, too many cons for a £60 mask. There are many other acid masks that do the same and are much cheaper. Try Clarifying or Resurfacing mask instead.
