I received this as part of a gift campaign from Suzykirei. It has a soft, jelly-like texture that blends smoothly into the skin without feeling sticky. It has no fragrance. It's a serum that apparently contains placenta and various anti-aging ingredients, so I was looking forward to seeing changes after using it, but after using up the whole bottle, I didn't notice any changes at all. It didn't irritate my sensitive skin, but I didn't feel like it was leading to healthy, firm, and moisturized skin.
I received this as part of a gift campaign from Suzykirei. I'm writing this review after I've used it, so it's been a while since I received it. This is my first time using this brand. It seems to be a product specialized in firming, radiance, and anti-aging care. It's supposed to be used after the brand's face wash and natural oil, but I use it immediately after washing my face. It's a thick, milky-white serum. However, it doesn't feel sticky on the skin surface for long periods of time and doesn't interfere with the next step. I used up the whole bottle, and I haven't noticed any significant changes to my skin. However, I no longer feel dry after skincare. I think there might be a synergistic effect if I use the entire line. You can't really tell the difference with anti-aging care until you've used it for a long time. I have other products, so I don't think I'll be buying it again soon. If it weren't for this opportunity, I probably wouldn't have tried it. Thank you.
I won a giveaway from Suzykirei! It's super easy to use and soaks into the skin, which is great. It blends into the skin quickly and I highly recommend it. It doesn't have any particular scent, so you can keep using it without worrying about it! I want to keep using it and keep my skin beautiful!

I received this as part of a gift campaign by Suzykirei. It's a beauty serum with a strong oily feel, so it feels sticky when applied, but after a while it spreads and penetrates into the skin. After washing my face the next morning, my face feels smooth. I'll continue to use it.
