I have bought it many times and I really feel the whitening effect.
I've been using HAKU's serum for many years, and I bought this because it seemed like it would provide more aggressive whitening care. It's a thick lotion, and looks like it could replace toner, but it's meant to be used after toner. I feel like it's more moisturizing now that I've added one more step. Since I started using HAKU, I haven't had any new blemishes, so I'd like to continue using the two-step method for aggressive whitening ^ ^
Received from the Shiseido Online Store! \HAKU's unique stratum corneum care serum/Loosens the stratum corneum with rich moisture. "HAKU stratum corneum care serum [quasi-drug]" Add it to your usual whitening serum! While preventing blemishes*, you'll also get a moisturized, clear complexion and continue to shine with "beautiful, luminous skin." This thick, lotion-like serum glides smoothly and slowly loosens the stratum corneum. The moisturizing effect lasts for a long time, preventing dryness and rough skin, which is great! The cotton is "Shiseido Beauty Up Cotton" which feels soft on the skin. ◎ Be sure to check it out! ■HAKU stratum corneum care serum [quasi-drug] ■Shiseido Beauty Up Cotton G* Suppresses melanin production and prevents blemishes and freckles.
I have acne-prone combination skin. If you're not satisfied with the cotton application, try pressing it in with your hands! At first, I followed the instructions and applied it with a cotton pad, but it didn't improve or worsen, so I wasn't sure what to make of it. It does have a strong alcohol smell, but it doesn't irritate my skin...or so I thought. I tried pressing it in with my hands, and found that it worked better for me! My skin felt soft and fluffy immediately after application. This also seems to help the serum I follow up with penetrate better! The next morning, my skin was still soft, plump, and radiant. I'm currently using Ultimune, so I won't be using it continuously (for financial reasons lol), but I think it might be a good product to use when I feel my skin is getting rough. *I used the 13ml mini size that came with the whitening serum.
I first experienced the effectiveness of this wipe when I went to the beach in the summer and got sunburned despite using sunscreen. I used it in combination with HAKU's serum and by the end of autumn that year, my skin tone had completely returned to normal. I'm in my 30s, so if I hadn't done any other skin care, I'm sure my skin tone would have taken a long time to return to normal...lol. Since then, I've always included it in my post-summer skincare routine!
