Ok, first I have to applaud for the quickest delivery ever!. Seriously, I purchased and this was delivered in less than 24 hours. Now, I absolutely love this mask. The price is a bit steep but totally worth it, I bought this for my acne marks, inflammation, redness, and of course for anti-aging purposes. This was a huge step up from an led light mask I previously purchased from amazon that was plastic and really uncomfortable. It applied pressure on my nose so I ended up returning. Because this one is flexible and does not need to be plugged into the outlet while using makes it extra comfortable. Plus it's FDA approved. I also love that it has an automatic 10min treatment so it turns off after 10mins. I've used it 4 nights in a row and I have definitely noticed a reduction in redness and inflammation. I can't wait to see the anti-aging benefits. Thank you for the samples. I can't wait to try them.
