I'm currently using the second bottle of the one-to-one release. The usage experience is good, and there are no skin troubles or issues. Even for someone with super-sensitive skin with an allergy rating of 1700, this item can be used for anti-aging. I've been using it for 3-4 weeks, but I'm not sure if the anti-aging effects are visible yet. At first, I used it very generously, but now I'm using 4-5 drops or one full squeeze of the dropper per application to avoid wasting it (though this is still considered a generous amount, as I used it more like a toner when I first started using the first bottle).

Although it feels expensive as a poor person, it has a skin toner-like formulation and a small ampoule volume, so I use it up quickly. I trust and use it as it is a certified improved product, but I'm not sure if it's actually effective on my skin. I'll have to think about whether to repurchase it.

This product works quickly and effectively, so I've already repurchased and used it several times! It has a light, watery texture, so it absorbs quickly and feels refreshing. I've used it multiple times in layers after laser treatments, and when I apply and pat it in, it gets absorbed right away, so it's great for intensive care too! It's also good for post-dermatological treatment care, and it's effective for soothing troubled skin and recovering from scarring. It seems to help calm redness as well! It's a product that really boosts my overall skin condition, so even after I finish a bottle, I find myself thinking about repurchasing it. I'd recommend this to anyone with skin concerns - it's worth trying out!

Absorption is good and the effects are great, so I use it frequently, but the capacity is a bit small, which is disappointing.

After applying the ampoule, using a beauty device to absorb it can make it more effective!
