I'm using
- Biotherm Source Therapie Sheet masks
- Neutrogena fairness masks
- Shiseido clay mask
Of the 3, i think the Biotherm, being most expensive, is the most
useless.. about $70 for 5 sheets.. After i used, i dun feel any
difference, my skin don't really glow or feel moisturised... and i
also dun like the smell... 
waste money liao... 
Neutrogena one is more moisturising.. can feel the effect..
As for the Shiseido one, after using, seems my pores can "breathe"
again.. but the effect is short-lived.. like 2 days lidat...
