I started using this all-in-one gel because I wanted to achieve clearer skin! It has a bouncy texture. It feels fresh and easy to apply to the skin. It has a moisturizing feel, so I would definitely use it when I'm concerned about dryness! It's not sticky, so I think it's easy to use in any season. The "Moist" version I use is said to contain highly moisturizing ingredients, so I would recommend it to anyone who feels like all-in-one products aren't enough. The slim tube-type packaging makes it easy to take with you when you stay overnight, which is great♪ I want to keep using it to achieve my ideal skin!
I received this as a gift from Suzykirei. Thank you. It's a moisturizing product with excellent moisturizing properties, so I think it's perfect for fall and winter. I have some dark spots on my cheeks, but I haven't noticed any noticeable changes. I've only just started using it, so I'll wait and see how it goes.
I won't know if it has any whitening effects until I continue to use it, but I like that it can be used on dry, sensitive skin without irritation, and that it has a refreshing texture yet is still moisturizing! It comes in a slim, lightweight tube, making it easy to carry around and hygienic, which I also appreciate.
I won this product as a gift in early summer and tried it out, but it was so moisturizing that I thought it might not be suitable for summer, so I started using it again in November. As I expected, it's perfect for this dry season. I apply a small amount (less than the size of a pearl) at night, and even after washing my face in the morning, my skin feels incredibly supple and moisturized. I've only been using it for a month, so I can't say if it's lightened my blemishes, but it has improved the overall tone of my face, and the skin on my cheekbones, where I apply it most carefully, has become noticeably more radiant and firm.
