Words From Our Community
Honest reviews from skincare lovers around the globe.
This oil is packed with serum ingredients and left my skin feeling moisturized the next morning. It has an oily feel, so as someone with extremely dry skin, this was a big hit for me and I think it will become an indispensable product, especially in the winter.
While it's classified as a serum, I'd call it a beauty oil. FAS's other whitening serum has the typical serum shape, but it feels completely different. This one is a golden-colored, heavy-feeling oil. It doesn't have much of a scent. The recommended amount is the size of a 100-yen coin, but a 1-yen coin was enough for me. It feels heavy in the hand, but it absorbs well and blends quickly into the skin. After it's absorbed, it leaves skin feeling very moisturized and plump and supple. I'd like to finish with a black cream, but perhaps due to the season, I feel like I'm layering it a little too much, so I layer a thicker serum (currently Shiseido's Vital Perfection Night Serum). This amount is just right for me. Since using this, I feel like my skin has become denser. I also feel like my skin has become more stable and stronger.
Maybe it was because I had high expectations for the lotion, but I'm not sure if I'll buy it again because it was so disappointing.
I happened to use a sample and loved it, so I bought it. The other products are included in the gift set, but I wanted this one on its own. Serums tend to be liquid-based. This oil is applied after toner, but even though it's oily, it's not sticky and blends well with the cream, which seems to enhance its effectiveness. It pairs well with the cream I use next, and my skin feels smooth and refined the next morning. I also like how it's non-irritating despite containing vitamin C derivatives, which are effective against pores. My skin gets super oily in the summer (May-October) and a little dry in the winter (November-February), so I'm changing my makeup routine. The winter ones tend to be sticky in the summer, but I think I can get by with just the right amount. Since a small amount is enough, it seems like good value for money. "Contains 31% black rice fermented liquid, a proprietary ingredient of FAS. It also contains two types of vitamin A derivatives to give skin firmness and radiance. It also contains two types of vitamin C derivatives, one water-soluble and one oil-soluble, which are delivered slowly at different times to address pores and lack of firmness. Despite being an oil, you can experience its texture being absorbed into the skin."
If you like FAS lotion, you should definitely try this! I used a sample, and just like with the lotion, I felt a clearer complexion, tighter pores, and less redness. The oil also gave me even more firmness and radiance. With some skincare products, you can't tell what's so good about them after just one use, but I love this one because I can feel the effects even after just one use. I've tried using it both as a set with the lotion and separately, and I recommend using the set because it's more effective. Of course, I also felt the effects when using the individual products.
