What it is
This foundation serum provides thorough support for vitamin C, an essential ingredient for beautiful skin. Recalca's first proprietary formula, Root W(R)*2, and two types of vitamin C*3 create a synergistic effect to treat skin damage*4, which can lead to troublesome skin problems. Additionally, the power of kiwi extract*5 delivers vitamin C deep into the skin*6, delivering a new approach to deeply radiant skin care*5. \ Point 1: 《 Two types of vitamin C*4 penetrate the stratum corneum with a special formula 》 The dual formulation of pure vitamin C (ascorbic acid) and amphiphilic vitamin C derivative (APPS) ensures widespread penetration of vitamin C into the skin*6. Pure vitamin C (ascorbic acid) is created using a unique process to create a thick texture, and this unique formula prevents deactivation until just before use, delivering fresh vitamin C to the skin*6. Furthermore, by incorporating powerful antioxidants such as fullerene*7, astaxanthin*7, and MAAs*7, we have achieved the ideal antioxidant cocktail. \ Point 2/ {Recalca's special ingredients that bring out the power of vitamin C*1} At Recalca, we focus on further enhancing the inherent power of vitamin C*1. Pure vitamin C*8 smooths and evens out sensitive skin, and when combined with Recalca's first proprietary ingredient, Root W(R)*3, it promotes even healthier skin. Furthermore, kiwi extract*9 promotes the penetration*6 of APPS (amphiphilic vitamin C derivative) into the skin, leading to clearer, more translucent skin with less noticeable dullness. \ Point 3/ {Specially designed containers that deliver all beauty ingredients to your skin} The peelable bottle's six-layer structure, including a special film that also blocks air, prevents the supply of oxygen, which causes oxidation, and suppresses product oxidation. *1 The first step in beauty serums *2 Bletilla striata root extract (moisturizing ingredient), gentian root extract (moisturizing ingredient) *3 Pure vitamin C (ascorbic acid), APPS (trisodium ascorbyl palmitate phosphate) (skin conditioning ingredient) *4 Moisturizing effect *5 Prevents rough skin caused by dryness *6 Stratum corneum *7 Product antioxidant *8 Ascorbic acid (skin conditioning ingredient) *9 Tone-up ingredient

A beauty consultant recommended this product to me some time ago, telling me that it was doctor-approved cosmetics and that I have dry skin. I tried the first bottle and it was so good that I'm back for a second one. After using the mist lotion in the line, I let the serum soak in and leave it for 3-5 minutes, then apply emulsion. This keeps my dry skin feeling plump and supple until the evening, so even though it's a little pricey, I keep buying it. The only thing that's disappointing is that the design seems to have been renewed from the first bottle, and while the container is larger, the contents remain the same (though it looks like a shoddy container). Personally, I think that if the volume is the same, there's no need to change the container.
It's very concentrated, so just a small amount is enough for it to penetrate deeply. I bought it because I wanted to try out some high-end cosmetics, and it doesn't seem like a bad value at all!
I've been using it for over six years now. There were times when I didn't use it for a while, but I always end up going back to it because it provides high-quality vitamin C without irritation, can be stored at room temperature, and is effective.
It contains Vitamin C, yet still provides excellent moisturizing power. Its slightly thick texture keeps your skin moisturized until morning when used at night. It also leaves skin feeling clearer and firmer, making it a serum you can use safely even in dry seasons. I love how the more you use it, the plumper and more toned your skin becomes.
