The #1 seller seemed to be the Super Aqua line. I immediately decided to get the water mask (US$38). After 3 uses so far and I have to say the moisture replenishing effect is average. It forms a thin film on skin when it dries and it's not penetrating like some of the other masks I tried. I would put it in the better-than-nothing category: good for daily maintenance and not for emergency.
When I saw the Lastian serum (US$120) with "retinol x 8" on the bottle I had to buy it. I have a weak spot when it comes to retinol.
The texture is a little too greasy (similar to the Isa Knox Double Effect Series) and it takes a little massaging to have it all absorbed. A drag. And as most Korean skincare products there are at least 4 layers to put on: lotion, emulsion, serum, then cream. After almost 3 weeks of use I have yet to see an anti-wrinkle effect. My skin feels softer and plump though.
My purchases came with a whole bag of free gifts! The joy of shopping in Korea. There are 3 tubes of face wash, Super Aqua paper masks, Super Aqua lotion, emulsion and cream in trial size.
I lam particularly impressed with the paper mask. With gel serum it pumps moisture and even out complexion all in 15 mins. Highly recommended!
