What it is
Galeniceuticals No.1 VC Serum is a fresh-mix vitamin C serum: you blend a powder of 20 percent high-concentration pure vitamin C with a hyaluronic acid lotion right before use, for maximum freshness. Aimed at dullness, uneven tone, texture, and pores, it delivers a luminous, hydrated finish. Each single-use set holds 0.2g powder and 0.8ml lotion.
Why it's different

Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
Why do I mix it before use?
Pure vitamin C is unstable once dissolved, so you mix the 20 percent powder with the lotion right before applying to keep it fresh and potent.
Is 20 percent vitamin C strong for my skin?
It is a high concentration, so patch test first and, if your skin is sensitive, start with a smaller amount and build up gradually.
What does it help with?
It targets dullness, uneven tone, rough texture, and the look of pores for a brighter, smoother, more luminous complexion.
How is it packaged?
Each single-use set holds 0.2g of vitamin C powder and 0.8ml of lotion, so every application is freshly mixed.

I received a sample from Suzykirei and used it. It's a product that requires you to mix the powder and serum each time you use it. It's smooth, so I was a little worried about whether the powder would be mixed properly, but when I applied it to my skin, it wasn't sticky and had a texture that absorbed smoothly. It felt quite tingly on my skin, but the next day my skin was well-hydrated and one tone brighter, which was great. The scent and elegant packaging made it feel special and luxurious when I used it.
The "handmade feel" of mixing the serum and powder just before use is fresh and fun! However, I was a little surprised by the strong tingling sensation on my skin. It may be more irritating to dry areas. The next morning, my skin was plump and radiant. It's a luxurious serum that you'll want to use before a special occasion.
Other reviews said that it caused a stinging sensation, but I didn't notice it that much. To be honest, I have very sensitive skin, so I was hesitant to purchase it, but I decided to go for it. It left my skin feeling moisturized, and the next day my skin tone seemed a little brighter!
By mixing the serum and powder just before use, it was great to be able to deliver them to my skin in a fresh state. After just one use, my skin felt plump and soft, and it was in great condition when I woke up. It's definitely worth continuing to use.
