It comes out as a foam, which is convenient, so I use it to wash my face in the morning. It leaves my skin feeling moisturized after washing, which seems to suit my dry skin. However, since it is a product for mature skin, it may not be suitable for younger people or those with oily skin.
I'd been wanting to try OSAJI for a while, so I happened to stop by a store and bought it as a morning face wash. (I was attracted by the fact that the salesperson mentioned that it targets skin glycation and contains vitamin C.) It leaves my skin feeling moisturized and not tight after washing, making it perfect for morning makeup application. It comes out as a foam, so I can quickly rinse it off, even in the morning. Another thing I thought after buying it was how cute it is to have in the bathroom!!! It's something that actually got me excited. I personally love the scent. It's very soothing to start the day with. I like jasmine but not rose, but I really liked it. I think it would suit those who like floral scents and those who like fragrant products. It might be too strong for those who prefer unscented scents...? It feels good, so I'm considering buying it again. I'll try it out for myself to see if a face wash can really change my skin.
The refreshing foam doesn't dry out the skin, and I like how it feels when I use it. I use it to save time in the morning, but there are days when I find the scent too strong. It's a smell I don't want to smell before or after breakfast (^_^;) It seems to suit my skin, but I won't be buying it again.
I was looking for a foaming face wash, and there were two types, but I heard that the Kai series was the best for aging, so I bought this for the first time to use in the morning! It has a faint rose scent, doesn't leave my skin feeling tight after washing, and washes off easily in the sink. I think I'll buy it again! It says to pump 3 times, but it seems like 1.5 to 2 pumps would be fine.
This single-use skincare product will be used from November 2022 to August 3, 2023, for morning facial cleansing. For my skin, cleansers with strong cleansing power strip away oil and cause irritation. I have dry, sensitive skin. (Please refer to my profile.) In the morning, I choose a gentle cleanser that only removes the previous night's skincare (such as the slippery, moisturizing feeling of cream). Since carefully lathering it is a pain, foaming cleansers are my only option. I like them. This one also met my needs and was exactly what I was looking for, so I passed. It also has a nice, soothing scent. (Scent in skincare is important, isn't it?) However, given the same criteria of gentle cleansing, foaming, and a pleasant scent, I thought Mama Butter, which I used previously, was better because it was cheaper. Mama Butter's foam density, firmness, and durability are also superior. (Reviewed.) If I were to purchase a similar product again, I would choose Mama Butter instead of OSAJI. It's not a bad product by any means, but when you weigh the price, it's a bit of a stretch.
