This product comes in a metallic tube which i think must help preserve the potent cocktail of ingredients that are to be found inside. It contains vitamins - including A & C - and actually helps to build collagen!! I decided to buy this after I went for a professional dermalogica facial at the salon called the Multivitamin Power facial. My skin felt so amazing for days afterwards like babies skin. I decided to buy the mask so that i could experience its benefits at home between salon treatments. This mask is bright orange and very thick, and smells a little citrusy. You have to apply it to cleansed skin in a thick layer, and leave it on for 10 - 15min. As it works (feels like your skin is drinking it in) it changes to a paler orange. My only gripe is that it is so thick that it is difficult to remove, they recommend tissuing / using a cotton ball, but i find that only washing it off with warm water really works. It doesn't leave a residue and is not fatty / greasy. But your skin feels and looks amazing afterwards, it is a miracle product. My skin feels so moisturised after using this that i hardly need to moisturised, and my skin takes on a clarity and brightness that no other product i've ever used has matched. This is one product that I cannot ever live without and so I budget for it. i am so impressed by this, that i now use some of the other products in the multi-vitamin range, including the amazing lip/ eye cream. if you are worried to try this because you have acne skin - don't be! I used this before my acne cleared up and it even seemed to have a calming effect on angry red, irritated pimples.
