I used two bottles. This serum contains 10% vitamin C. It's a clear, smooth, oil-like liquid that gives off a slight, tingly warmth when applied to the skin. I used it up in about a month, so I felt a warmth right down to the end and there was no discoloration. While many VC serums are heavy and oily, this one has a light, smooth finish. However, when I looked at the ingredients, I was surprised to see that it was packed with essential oils. The scent is natural and bitter citrus. It's rare to see an "expiration date" listed, even though it's made in Japan. One thing I noticed was that the dropper design tended to drip even without any special care (the top wasn't squishy). I occasionally spilled some in the bathroom, which was a bit of a waste. I used it all up, but I'm not sure about its whitening or pore-enhancing effects. Obagi C10 Serum is probably the most well-known high-concentration VC serum of this type. I was looking at Obagi and thought it was a pretty high-end product, but Plus Pure is more expensive even though the amount is smaller...! (Obagi is 4,400 yen for 12ml, this is 5,500 yen for 10ml) Obagi is cheaper and somehow has the security of a major brand, so if I were to buy this kind of product in the future, I think I would choose Obagi.
It's smooth and almost transparent, so it's easy to use. The Vitamin C smell isn't too strong.
I tried Pluskirei's Plus Pure VC10 serum, which contains 10% pure vitamin C. It's perfect for "first-ageing care" for those in their 20s and 30s who are starting to experience age-related concerns. Its light texture and non-greasy feel make it easy to absorb. It's great for before bed, as well as for morning skincare, like before applying makeup. It also helps make your makeup last longer. It's free of six additives, making it gentle on the skin and a recommended vitamin serum you can use with confidence. #ExcellentMedical #pluskirei #Pluskirei #PlusPureVC10 #PureVitaminC #VitaminCSerum #HighConcentrationSerum #PoreConcerns #FirstAgingCare #monipla #pycno_fan
I received this 10ml bottle of Plus Pure VC10 from Plus Kirei's pre-campaign. Features: Plus Pure VC10 from Plus Kirei is a serum containing 10% pure vitamin C, crafted using a unique A-PVC design. *Please be sure to use sunscreen when using Plus Pure VC10 (no need to use it before bed). This vitamin C* serum has a refreshing lemon scent. *L-Ascorbic Acid: Skin-conditioning ingredient. Since it's the season when sunburn is a concern, I use it as a pre-makeup skincare routine on days with strong UV rays. ◎ The serum's refreshing and smooth texture makes it easy to apply to dry areas. The serum's moisturizing properties leave skin looking translucent and radiant. It seems like it would work well in the morning with sunscreen. I love citrus scents, so I'm thrilled to have won the pre-campaign.

[Plus Kirei/Plus Pure VC10] I love the thick texture, how it spreads and blends well with the skin. It feels oily, but it blends in quickly! I love it and it doesn't feel cakey even when I use it before applying makeup. I recommend using it within a month, so it's the perfect size. I recommend storing it in a cool, dark place. It uses a unique technology that stabilizes L-ascorbic acid (a skin conditioning ingredient) without using any water, delivering pure, underivatized L-ascorbic acid (a skin conditioning ingredient) right to the stratum corneum!
