Great to use twice a week. No particular scent and does not leave skin feeling tight at all like some clay based masks can do. I like to use a mild glycolic peel cleanser in the evening and use this mask the following morning, I have a very pale complexion that seems to magnify any blemish or dryness and is prone to looking dull and this routine really perks up my skin.
I use it in the shower, as it it coal black and sprinkled muddy looking droplets all over the sink the first time I used it. Shake and squish the tube a little to mix it up, as it does seem to separate slightly into a more solid part and a liquid over time. Squeeze out a 10p coin sized amount and apply all over face and neck, leave to work while you get on with the rest of your shower and remove with a wet washcloth (preferably dark coloured!) after a few minutes.
Also works nicely as a quick facial scrub: use a pea size amount,mix with a little water and massage onto face and neck, remove with a damp washcloth and rinse with cool water.
I purchased with my BB reward points initially, and will be a repeat purchase once I finally run out - it seems to go a long way. Definitely a staple in my skincare routine now.
