I received this as a gift from Suzykirei. I've used body lotions before, but this is my first skincare product. It's a white milky type with a rather loose texture, not too hard. This makes it easy to spread. Even though it's loose, it's very moisturizing and supple. I was worried about dryness from the heating, but after applying this, my skin didn't dry out, even in the morning. It's not sticky, keeps my skin moisturized, and spreads easily, so I thought it was great. I caught a cold after receiving it and had to blow my nose a lot, but applying this helped calm my stinging and calmed me down. I'll add it to my nighttime skincare routine.
I received this as a gift from Suzykirei. Thank you! I'm currently using Hirudoid cream and lotion, which were prescribed by a dermatologist for menopausal skin problems, such as itching on my arms and shins. Maruho, the manufacturer of Hirudoid, jointly developed this moisturizing quasi-drug skincare product with KOSE, so I was very happy to receive it as a gift. It's odorless. The texture is more moisturizing than a typical all-in-one product and slightly more viscous than a lotion. It blends easily into the skin. It's smooth and non-sticky after application, which is different from Hirudoid. Hirudoid has more moisturizing power, but it feels sticky after application. I thought it was a great product, specifically designed for facial skincare. Before applying makeup in the morning, I found this product to be better than Hirudoid, as it kept my foundation from smudging and felt better on my skin. The recommended application is 2-3 pumps. As an adult woman with large pores and dry skin, I needed 4-5 pumps at night. My daughter, a student, says the regular amount leaves her skin feeling smooth and moisturized, and it's easy to use after washing her face. It's the best! If two or three pumps isn't enough, you can add your own cream at the end. I needed a little more than this to get by with just this one bottle after washing my face, but it's moisturizing and trouble-free, and it's great because I don't have to do a lot of skincare routines. I usually use expensive skincare products, but recently I've been using this one every morning and at night when I'm tired. I've tried several all-in-one products from other companies in the past, but I never bought them again. Karte HD is safe for sensitive skin, and there's no tingling or itching, so it's perfect for use. It's easy on the wallet, so I can use it generously. I want to keep using it for a while. I recommend it.
I received this as a gift from Suzykirei! Thank you very much. First of all, it was jointly developed by KOSE and Maruho, so I think it's a safe, reliable product. It's an all-in-one product, so I thought it would be convenient and time-saving when I'm short on time, like in the morning! The texture is like a light cream, smooth, and easily absorbed into the skin. However, I have extremely dry skin, so it was a little lacking in the winter! I think it would be just right for summer. I also like that it's easily available at drugstores!
It's supposed to be a one-bottle product that combines lotion, serum, emulsion, and cream. ●The cream is also included, so the texture is a little thicker than emulsion. ●It spreads easily and blends in well. ●I have great confidence in the moisturizing heparinoid. .Is it all focused on moisturizing? Now, I always use an all-in-one product in the morning. I've been using each of the three Aqua Label shades. Personally, comparing it to Aqua Label, I'd say gold >> this product ≧ red >> blue. It blends in easily, but it's just enough to leave my face feeling smooth and comfortable, just before it gets sticky, which gives my face a radiant glow. It doesn't seem to have any anti-aging effects, but if you use this for now, you won't have to worry about dryness. It's fine even indoors with humidity levels of around 30%.
I'm glad I tried it! It makes my skin soft and supple, and the best thing about it is that it's an all-in-one product. It was perfect for my dry skin!
