I love Sulwhasoo deluxe samplers. They're such a great way to test out products to see if they're worth the $$$$ investment, since their full size product prices are nothing to laugh at. I've been thoroughly enjoying the Clarifying mask, although there is a bit of learning curve in applying it without making a total mess. I do find that applying after your serums helps the peel off mask come off more easily. Also been using a mask brush to apply rather than my fingers for a more even (and less messy) application. Also really like the Overnight Vitalizing mask - the scent is not as strong as the Clarifying Mask, and it's very smooth and creamy. I'm not sure how much I like the Radiance mask yet. It smells similar to the Overnight Vitalizing mask, but somewhat sharper. The effects seem similar, but I haven't used it enough yet to say if it's as effective as OV. As for the Trufresh mask - I haven't even opened it yet. It's apparently a cooling mask that is geared towards summer, so I'm saving it for the warmer months and see how I enjoy it then. Would love to see more of these similar product comparison collections (i.e. eye cream collection, cleanser collection, etc.).
