Kose Shirosumi Whitening Serum


I’m satisfied with the skin fairness that I have, but the post-acne marks, freckles and veins still make a long way to the “clean and clear” level. I can’t change my sensitive skin’s nature, but whitening serum is helpful to tackle the most annoying post-acne brownish marks. I bought few whitening products lately where Kose’s 2009 newly-launched exquisite crystal white angel — Shirosumi is part of my splurge.


Kose Shirosumi-2


According to Kose, Shirosumi  counteracts epidermal cell’s function of conveying melanin to the skin’s surface. Contains Prune Enzyme resolvent to suppress epidermal cells from absorbing surrounding melanin, thus promoting whitening and moisturizing effects. Would that means Shirosumi is better for prevention then? I ponder.


Kose Shirosumi Whitening Serum-content


Being Kose’s unusually fragrance-free product, the Shirosumi is dewy gel-consistency, runny on skin that feels like moisturizing, thus 2-3 squirts are really enough for face and neck. Due to the moisturizing consistency, it takes a while to be fully absorbed. May be the alcohol or other reasons that always cause me redness upon application, but overall no discomfort feeling yet moisturizing.  Apparently not a good moisture retainer but shows satisfied result of whitening on me. I actually didn’t notice any obvious change of my skin tone because I was with other brightening care such as Sekkisei Supreme Lotion and DHC Retino A Pack, thus my skin tone is consistently looking even and bright (but not clear), however, I do noticed the change of my neck.


Previously I noticed my neck and my face is one shade difference. Scratching my head, I do apply whatever I used for face for my neck as well, seems like it is either the mask doesn’t cover the neck zone, or I didn’t exfoliate my neck properly. I don’t want to tone down my face by darker foundation to match the neck tone, which will look utterly weird because my other part of body is as fair as the face. Honestly, this is my real reason for purchasing a whitening serum since I knew AHA and Vitamin A will be more effective on acne scars.


Shirosumi texture


With the Shirosumi serum, my neck became noticeable slightly fairer in first week! H.a.p.p.y ! By the way, remember to exfoliate the neck zone regularly too. Nevertheless I see no obvious result after 2 months, although skin had brighten up overall. My freckles became slightly smaller (most probably due my consistent using of whitening products these few months ), neck line became less visible (any quality whitening should be able to deliver this) and good for overall brightening (any whitening product should able to have this done).


The inner design of this serum is quite different from usual pump design that I have ever seen. The airtight space is slowly pushing up with the leftover content until it hits the short pump. I’m not good to describe, so please refer to below attached picture that shows disassembly of the serum, the cotton bulb tells the remaining space just enough for the short pump.

By using Shirosumi day and night, the “N.E.C.K” mission theoretically completed beautifully, persistent attention to neck still on going because the serum only works when it is on. Overall I think Shirosumi is quite nice to use but I’ll not repurchase because it made my broken capillaries vividly! With the reasonable price 1500 baht for 30ml, Shirosumi Whitening Serum is still worth to consider if you don’t have sensitive skin. Bought it for 1350 baht during promotion.
