I received this as a gift and it was the first time I'd heard of this brand. Even though it's an oil, it's not sticky and is very easy to use ^_^ I thought it was moisturizing and good for preventing dryness.
It has a very nice scent and is soothing. The smooth oil is pleasant to use and I will definitely buy it again. A small amount is enough to moisturize, but I would like to use it on my shoulders and arms for whitening purposes this season, so I wish it was a little cheaper.
I received this as a trial gift from suzykirei. In the morning and evening, after washing my face, I apply one pump to my entire face, then apply lotion, milky lotion, and cream, and finally apply one more pump mainly to my cheeks. I used to be worried about redness on my cheeks, probably due to dryness, but since I started using this oil, the redness on my cheeks seems to have subsided. It has a nice scent, is not irritating, and my whole face felt moisturized the next day.
I won this as a gift from suzykirei. This oil can be used when your face is wet, so I keep it right next to the bathroom door so I can reach it easily. I apply this to my face first, then use lotion, serum, and emulsion, and the lotion seems to penetrate very well! Also, my skin has not become rough at all. This beauty oil is light yet moisturizing, so I think it can be used all year round!
I got this as a gift and learned about this brand for the first time. It's supposed to be used when your face is wet, but I have a habit of wiping it off, but one pump spreads well enough that you can apply it to your whole face. I use two pumps at night, and it's very moisturizing, so even if I put it on, take care of my kids, and then apply lotion, my skin doesn't dry out. The dry winter and the pollen from the warm weather made my skin so dry that it would peel off, but since I started using this oil, I haven't had any problems at all. I'm not sure about the whitening effect yet, but I'm looking forward to it.
