My mind is blown at all of the negative reviews that this product is receiving. First, for everyone complaining about the mask not staying in place there's a very simple solution: Apply the mask to your lips while you're laying down!!!(DUH!!!! Lol) My mask stayed in place the entire 20 minutes!!! Afterwards I just rubbed in the extra serum. My lips were so soft and smooth that I IMMEDIATELY bought the full size 5 pack. This product is amazing, so glad I received it in my September box, with the colder months ahead I will definitely be using this product to keep my lips on point!!!!
