1. The basis of skincare is a healthy body: First, as a general theory, I will explain the problems that the skin has. Even healthy skin is always exposed to physiological stresses such as oxidation, glycation, inflammation, and hardening. We collectively refer to the skin's natural ability to recover as "skin strength", and healthy, youthful skin can cope well with these stresses. On top of that, in order to maintain this healthy state, many people pay attention to their diet and take care of their beauty. We particularly recommend that you adopt actions that contribute to improving blood circulation in your daily life and address skin risk factors as soon as possible. 2. The Role of Serums: Serums are for special care in which each individual understands their skin type and uses chemical ingredients to directly address the problem. The word "high concentration" in the streets is not necessarily an appropriate word for guidance. Fortunately, the skin can "see" various phenomena that suggest abnormalities, so we can notice changes in shape (wrinkles and sagging), color and shade (blemishes, dullness, freckles, etc.), and texture (dryness and texture disturbances) as signs of abnormalities. For example, they are also associated with microscopic inflammation inside the skin that occurs on a daily basis. Regardless of the factors such as oxidation, glycation, inflammation, or hardening, we would like you to choose a serum that suits your situation. 3. What Nabocal values. Navokal's serum emphasizes an oriental approach that helps the skin autonomy. Utilizing the knowledge accumulated by our predecessors, we have developed a prescription that approaches the factors that can spark skin problems in advance. We try to avoid irritating ingredients that are easy to feel that are found in some of other companies' products. The "feeling of use" that many people remember may be an irritation that sometimes makes the skin hypersensitive. The "skin conditioning" advocated by Navocal is to avoid or suppress irritation. This is why many extracts such as peony and eye leaves are added. In addition, carob fruit, which has been independently researched, is an ingredient announced in our press release. We believe that using what suits your skin condition intensively as needed is the original serum. [Explanation of background and premise] The reason why serums are difficult for consumers is because they are products in the "other" category. Lotion is used for daily "moisturizing" and cream is used to "cover with oil", but serum is, if I had to say, special care to clearly understand and solve problems. However, the market is flooded with products that claim to be mysteriously high-functioning, and the reality seems to be that individual consumers are ignoring their own skin type. Navocal recommends skin maintenance under a professional. Because we understand the importance of "customizing maintenance". [How to use] After preparing your skin with toner, take an appropriate amount (approximate: 3 pushes) in your hand and apply it all over your face.
