Age-wise, I'm getting up there, and I'm trying to incorporate more beneficial skin care products and processes into my life, but I'm often so busy that I just don't have the time for a lot of things. Luxurious bath soaks? Maybe once a year. Overnight face and hair masks? Forget about it. But I can handle a quick face mask a couple times a week!I've never used any of this line's product before, so this was a first time order/experience for me, but they've got several other products that have great reviews so I figured, why not?The directions in english say to apply the mask and leave it be for about 10 minutes, but I'm pretty sure the german directions (I don't speak german lol) say you can leave it on for 10- 20 minutes, so I took the middle road and kept it on for 15 minutes. I had no adverse reactions, so I think the 20 minute mark is quite doable.The directions didn't say how much of the mask to apply for each use... which is kind of annoying because for the price I don't want to be wasting it. I ended up doing my best to feel it out, and I think I ended up using maybe 6 pumps of the stuff?It doesn't have any fragrance added to it, which I love, because if something is designed to soak deep into my face, mere inches from my brain, I'd much rather there not be any sketchy chemicals or unnecessary ingredients, ya know? It does have a pleasant and subtle smell to it, though.It soaks into the skin a good deal, which is probably why I used so many pumps, but it does hit a point where it feels like it's just hanging out on top of the skin, and that's the point where I decided to leave it and give it the extra time to soak in. After letting it sit for 15 minutes or so, I jumped in the shower to rinse it off because that's just about the only way I have time do any messy pampering-- pre-shower. So anyway, my face got a good hot rinse and then some while I washed the rest of myself, which, I then realized was probably just drying out all the benefits that the mask just provided, but it was too late anyway. After drying off I went straight to the mirror to see if I had indeed just washed away all the glory and I was astonished to find that my skin actually looked refreshed! Even my super untouchable smile lines seemed to be faded and not as noticeable (that alone is motivating enough to use this stuff regularly.) I am writing this review the day after trying it out and my smile lines still appear to be reduced. Like, what wizardry is this?? I used this mask one time! ONE! I am sold y'all. This stuff feels like a bottle of miracles. I'm excited to use it again and see just how much magic I can milk from this bottle.
