I've been using Missha skin-care and cosmetics for the past 3
months and found the products very affordable and suitable for
me!
Having moderately sensitive skin type, I've been using the
Rosewater range of face care products-includes Rosewater cleanser,
toner, Rosewater Controlling Serum and Emulsion.
The DSW Water Supply Cream is really effective in moisturising, and
its especially well absorbed yet not oily (cos its oil-free)
I'm also recommending the Yogurt Pack (comes in 3 forms- peel-off,
tub, sheet mask and 5 flavours). I've used all the 5 flavours and
currently on whitening craze so using the Strawberry Yogurt
Pack(for oil-control) on Tuseday and Fridays, together with the
Kiwi Sheet Mask on Weds and Saturday.
the Make-up cosmetics is really "cheap and good". Found the Magic
eye-Tip especially lasting and love the many nail polish and
lip-tick colours! 
They currently have 3 outlets:
1. Far East Plaza Level 3
2. Parco Bugis
3. Century Square Level 3
Go have a look, but be prepared to browse cos they really have a
huge selection of goodies! Have fun!!
