It has a slightly thick texture. Depending on your skin type and the season, you can use it as a substitute for lotion. It's easy to use and doesn't cause any irritation.
Now onto my second favorite. When I became pregnant, my skin got worse, with more acne, uneven texture, and dullness. I stopped using everything I'd been using and switched to products that were gentler on my skin. When I started using this serum, my skin troubles decreased significantly and my skin became brighter. It's moisturizing but not sticky, and even now that I've given birth and my skin is better, I still keep it on hand as a good luck charm. It's comfortable to use, moisturizes well, and doesn't dry out or dull my skin, even in winter, so I end up using this one all the time. As I get older, I'd like to use products that target firmness and dark spots every day, but... I think I'll repurchase it again.
This serum is non-irritating, light to use, and easy to apply. It's not an aggressive serum, but rather one that regulates the skin's condition to prevent irritation. The fact that it contains niacinamide is also a big plus. It's great for quick use when you're busy in the morning. When using a facial beauty device, you need a moisturizing gel, and this slightly thick texture works well at times like that, so I sometimes use it. I recommend keeping it on hand as a talisman for when your skin is prone to irritation, such as during the change of seasons or before your period.
I used it in combination with the lotion! It spreads easily and lasts a long time since I only need about four drops! Just like the lotion, it's refreshing, so it doesn't feel sticky even when used before makeup in the morning. It's non-irritating, so it's easy to use even for people with sensitive skin. It doesn't have any dramatic effects, but it does seem to maintain stable skin that's less prone to irritation!
[June 18, 2025] I have thin, fairly sensitive skin. I've been using it for about a week. It's not sticky or sticky at all, and it absorbs quickly, making it easy to use even on hot days. I like the feel. It doesn't get in the way at night, or even in the morning before applying makeup. When I apply it before makeup, it somehow seems to prevent dryness (deeper wrinkles) and enlarged pores. I'm not sure if it calms my rough skin, but so far it hasn't. I won a giveaway from Suzykirei. I can't say for sure if I'd buy it myself... [Added December 1, 2025] After using up the whole bottle, I suddenly wondered if my skin was actually in better condition while I was using it! It didn't really feel noticeable, for better or worse, but it seemed to calm my easily rough skin. If there's nothing else I'm interested in, I might buy it myself.
