I thought it would be worthwhile dissecting this serum in detail, so my apologies as this review is not going to be in the usual format.
Below are the whitening/lightening ingredients that I have identified:
-Mulberry extract – reduces melanin synthesis by inhibiting the Tyrosinase enzyme.
-Waltheria Indica – reduces melanin synthesis by inhibiting the Tyrosinase enzyme, anti-oxidant.
-Licorice extract – contains Glabridin, which reduces melanin synthesis by inhibiting the Tyrosinase enzyme, anti-inflammatory.
-Papaya enzyme – contains Papaine, an enzyme which promotes skin exfolation/turnover. It is not a whitening ingredient.
-Ascorbic acid – inhibits melanin production.
-Tranexamic acid – acts on the chronic mild inflammatory condition at the sites of spots, to suppress melanocyte activation (from Shiseido’s website).
-Oligopeptide – inhibits tyrosinase but also halts melanosome transfer well as melanin synthesis.
If you have a look at O’slee’s website, they have a freaky video
wherein a liberal dose of the serum turned an iodine-stained water from brown/red to white within seconds with some vigorous stirring! Quite alarming… to be honest I don’t believe the video (IMO they must have used a very strong version or altered some condition or the other), as only very harsh bleaching products could do that; and if it is true then I would be as white as a sheet of paper now after using it for some weeks.
I decided to purchase this as this brand is quite established in asia and after reading up on the background and ingredients I thought it would be safe to try.
At first impression, the packaging and the bottle are very nice compared to other asian brand products of the same price range. They are well-made and not plasticky. The bottle itself is made of ceramic/glass and is quite heavy.
The serum itself is not white and runny as in the freaky video mentioned above, but rather yellowish and thick. The fragrance is quite strong and smells of roses… and something rather synthetic. I don’t mind it but it might be too much for some people. I hope mine is not a bad batch!
The texture is sticky and oily. Unfortunately it doesn’t spread easily over the skin, so I need at least 3 pumps to cover my face and neck. It also feels quite heavy on the skin, to the detriment of those who like lightweight serums. However, like most serums, it sinks into the skin and my face feels fine the morning after (not overly greasy). I am not using a moisturizer on top of the serum because it would be way too greasy. So now my nighttime regime is wash>b.liv serum>lotion>this serum.
Whitening effect… hmm, maybe it’s due to the other products in my skincare regime which has been updated, but I do believe that this has helped a little bit in terms of lightening. I started using this in mid-September and I have noticed my face getting slightly lighter. One proof of this is the increased contrast between my cheeks and my dark circles.. haha.. unless my dark circles suddenly grew a shade darker!
I was alternating this with the isQueen night cream before, but I would like to see the concentrated result so I will be using this exclusively. Let’s see how it fares in the next 2-3 months.
