First you have to read my previous post here regarding the following product.
This is my review after using them for a week
I see my skin is getting clear-er, but on the cheek zone I feel they are a bit irritation, mild I may say, but I need more moisture there, so I use another product to help boost the moisture. I think this product is more safe to be used on normal to oily skin. Conclusion: Effective in terms of whitening but dry skin would not feel happy about the dry zones.
