Honest reviews from skincare lovers around the globe.
This serum has a floral fragrance that spreads throughout, making you feel incredibly luxurious. I received a sample when I bought OSAJI perfume and was enchanted by how well it penetrated and smelled. I'd used up all my other serums, so I finally bought this one! It has a natural, gorgeous scent that makes you want to take a deep breath. It's not a lingering scent, so I use it morning and night without worrying. It's thick, but I like how it penetrates quickly. Depending on the combination, it may not be quite moisturizing enough. I was just about to run out of my Toubert emulsion, so I switched to Curel's Freckle Prevention Care Emulsion and am seeing how it goes. If your other cosmetics are moisturizing, I don't think it'll be a problem. (I tend to prefer products that are light and absorb easily, so I generally use lighter products.)
Osaji's gentle serum. It has a lovely, gentle scent and gentle moisture, making it a great serum. The frosted glass container is also delicate and cute. However, although it was good, I'm not sure if I'd buy it again. I might come back to it after trying out a few other serums.
I used a sample. The scent is natural and seems fine. I don't think I'll know the effect until I use it regularly, but I'm not that interested in it, so I don't think I'll buy it.
I was concerned about the yellowing of the skin around my mouth, and I assumed it was due to glycation, so I bought this serum, which I heard contained anti-glycation ingredients, to see if it could help. It was my first time buying a serum at this price point, so I was excited. It's only been about two weeks since I started using it, and while I haven't seen any dramatic changes, I do feel like my skin is clearer. Ultimately, after careful consideration, I've concluded that the dullness I'm concerned about is most likely due to dryness, and I'm not sure how effective the anti-glycation ingredients will be on my skin. Currently, I'm using it more as a preventative measure than for improvement, so I was hoping to continue using it, but the KAI series is being discontinued. Anti-glycation cosmetics are rare, so I hope they continue to release serums. The subtle scent is pleasant, not too sweet, and easy to use.
I received a sample when I went shopping. I used it in the following order: primer → lotion → serum → emulsion. Because it's gel-like, it absorbs smoothly into the skin. It's not sticky and doesn't interfere with makeup. It was very easy to use, but it didn't really work for me... I prioritize immediate results, so I don't think I'll be buying the full product.
