< to the skin that is asked, "What kind of care do you take?" > Plump, well-textured and transparent skin. Once you have prepared with CONCIO's basic care, it is natural to want to aim for skin that everyone longs for. With the aim of making such wishes come true, we do not thoroughly use ingredients that put a burden on the skin, and contain pure vitamin C*. It is a vitamin C serum made with only three ingredients necessary for ideal skin. * Ascorbic acid < Slowly and directly penetrates into the stratum corneum> Because it is a dense blend that does not use a single drop of water, the skin becomes warm and soft the moment you apply it. It is not disturbed by superfluous things, and pure vitamin C penetrates directly into the stratum corneum. < worries that can't be hidden with foundation> Skin problems that appear with age. Vitamin C was chosen as an ingredient to combat fine wrinkles and dullness due to dryness because of the numerous papers and surveys shown its effectiveness. ・Papers showing promotion of collagen production ・ Clinic survey comparing the degree of improvement of skin firmness, spots and wrinkles for women aged 40~59 ・Research on the use of vitamin C for the prevention of skin changes and pigmentation due to photoaging, etc. "I don't want to look in the mirror." It is a serum that is close to such worries unique to adults. < sorry for being selfish. But I want to be prettier> One day, we received this message. "When I met CONCIO, my skin was ready. Until now, I thought it would be nice to find "skin care that can be used normally every day" As soon as my skin calmed down, I had the desire to be more beautiful. I want you to make a product that can be used on my selfish skin." <To make it more beautiful> Our mission is to respond to the earnest feelings of people who have been struggling with skin care. With that in mind, the answer we came up with is Vitamin C Booster. <Why vitamin C> There are many vitamin C serums out there. ・ Worries due to age ・Tone up ・Skin texture ・Hari ・Dry wrinkles This is because vitamin C is an ingredient that can deal with many skin problems. However, if you look closely, you will find that in many cases, "vitamin C derivatives" are included. < derivatives are not used> Pure vitamin C is a very delicate ingredient. It will break if it comes into contact with water. That's why derivatives that are combined with other components to make them less fragile are often used. However, derivatives combined with other ingredients may cause variations in the concentration of vitamin C itself. < firmness, texture, fine wrinkles*, dullness*, pores> In order to deliver the true power of vitamin C, it is necessary to contain pure vitamin C. With this in mind, we created a serum that contains only pure pure vitamin C* and two other ingredients. * Fine wrinkles, dullness, and pores due to dryness * Alcorbic acid < Penetrates the skin gently and straight> Since it is a dense blend that does not use any water or extra ingredients, vitamin C is not disturbed by anything and goes directly to the stratum corneum. It works on areas of concern and raises the power of the skin. < recommended usage> Vitamin C Booster is best used in conjunction with CONCIO's basic skincare routine. Immediately after washing your face, apply CONCIO's All in One Serum to your entire face, and then apply Vitamin C Booster to the area of concern. After that, it is recommended to apply All in One Milk Cream all over the face. Why < pleased> Not "good-looking" things, but "good things". Something that is "easy" rather than "easy". That's because that's the standard that CONCIO prioritizes. In Japan, there are no standards for selling cosmetics with claims such as "additive-free", "organic", "natural", etc. Therefore, even if it looks good at first glance, it may actually contain ingredients that are burdensome to the skin. And CONCIO doesn't just care about human skin. We do not use ingredients that are not biodegradable and do not return to nature, or that sacrifice the lives and livelihoods of animals and other living creatures. CONCIO does not use ingredients to create an image, topicality, or a sense of luxury. Because it is a formula that does not add unnecessary things, we firmly approach the areas of concern. It supports firm and shiny skin with a perfect texture. * Not all people will be affected by skin irritation
