This is a review of Omija Whitening Serum, based on a sample received from my favourite e-bay seller.
Omija Whitening Serum is a white liquidy substance which gives non-sticky finish. There's a faint smell of alcohol. Thanks to this I suppose the serum absorbs very quickly, almost evaporates. Makes a good make-up base for oily skin types.
The sample was too small to notice any whitening effect. Some whitening products offer instant whitening, even if temporary, nothing like this was observed when using this serum.
All in all in my opinion this is a kind of product which does no good or harm. You may get it and you may equally well do without it.
