This mask is probably interesting to anyone focusing on anti-aging as the essence does contain 10 different peptides that work to restore elasticity to the skin. Though the peptides are at the end of the ingredients list, it's not like you need a high concentration for them to be effective. his was the only mask out of the group that contained dimethicone which I am always iffy about in skincare. It is present in a relatively low concentration compared to other masks I have seen where it is the second or third ingredient. This mask also had a very soft scent - slightly floral with the essence taking an hour or two to fully absorb into my skin. This was quite a bit longer than the other three masks so I can only assume it's the peptides? My skin felt bouncier than with the other masks, so I have a feeling it might be one of the more effective ones!
