Upon applying, you will look and feel like you've just encountered Slimer from Ghostbusters. No amount of massaging will get this mask to absorb into your skin, so I ended up washing it off after 20 minutes, like I would any other mask. My skin still felt a bit sticky, so I wouldn't recommend using it before going out.
The mask has a nice warming sensation when you massage it into your skin. It spreads really easily, unlike clay masks.
My skin got extremely dry this winter. After using the Elizavecca Vitamin C Ample Mask for just a few days, I noticed my skin plump up and the flakiness disappeared completely. I also have a few dark spots from cystic acne (for about a year) and they are definitely starting to lighten since I started using this mask. I do have somewhat sensitive skin, but the ascorbic acid didn't irritate my skin at all or cause me to break out.
In my opinion, the mask I received didn't smell like citrus (but did taste like it--hard not to get a bit on your lips). It had a bit of an odd scent that I couldn't identify, but I didn't find it offensive (and most frangrances bother me).
After doing some research, I found that Elizavecca suggests that you can use this product as a sleeping pack, underneath your makeup, or mixed with your makeup. While I'm really happy with the results I've had using this product as a mask, its consistency is way too sticky to use in any other manner.
