I first tried the Annie's Way jelly masks in 2015, and I've continued to buy them since. I've also tried the snail, honey, and lavender variants, but the HA + Arbutin version continues to be my favorite. The masks have a firm jelly texture that you layer thickly onto the face, leave for 15-30mins, and then scrape and wash off. Each mask comes with a spatula that you can use to keep the jar hygienic, and it also helps to remove the mask from your skin. The first time I used this mask I was SHOCKED at how noticeable the results were! My face looked so much brighter, and there was a visible reduction in blackheads and clogged pores. The mask hydrates as well, but I wouldn't get it for that purpose since you can get hydration from a cheaper sheet or wash-off mask. The mask won't always be effective if you use it regularly, so I like to use it every couple months as a pick-me-up. I store mine in the fridge for an extra cooling effect, which I find super soothing for my sensitive skin! Using it this way, one jar lasts me a very long time. I will say that the texture of this mask is so thick that it's pretty difficult to neatly remove from the skin after use. You can make this easier to wash off by using it before showering- but otherwise, I recommend scraping the jelly off with the provided spatula onto a tissue and tossing it out, then using a thick headband to keep the jelly out of your hair as you wash the rest off! This mask has also become a bit pricy to buy in the US, but if used sparingly, the large jar will last you a long time. If you enjoy masks and haven't tried this formula before, I really recommend them! Especially for dull and congested skin!
