1. Life has always struggled with the threat of UV rays: Since the birth of life on this earth, the first major test has been ultraviolet light. Life that has begun to advance into the shallow waters of the ocean is exposed to intense ultraviolet rays. Ultraviolet rays can cause buildings to deteriorate and cause paper to turn yellow. Because it has high energy, it deteriorates the irradiated material. However, seaweed has the ability to convert the energy of ultraviolet rays into fine motion and parry it. Nabocal uses the properties of this seaweed as an ultraviolet absorber. It was precisely because seaweed acquired this ability in the ancient sea that our life was able to get closer to land. 2. The Frontline of UV Defense Lines: In recent years, there has been a concern about the burden on the skin caused by UV absorbers. There are two main things. One is that the absorption of ultraviolet rays, which are high-energy, generates heat, which can cause irritation such as redness and hot flashes on the skin. The other is active oxygen. Oxygen is everywhere, but the energy of absorbed ultraviolet rays leads to the generation of active oxygen species, which damages skin health. In response to these concerns about absorbents, there are also products that only use reflective materials that claim to be "non-chemical", but it is not easy to defend against physical reflection alone. The skin when viewed at a microscopic level is too wide to be covered with reflective materials. 3. Sunscreen blind spots that don't show up in the "numbers": This product from Nabocal does not compete with the quantity of reflective materials. Nor am I going to claim that seaweed, a natural UV absorber, is all-purpose. What we focused on was adherence to the skin. In the first place, SPF and PA values are calculated on the assumption that the specified amount is ideally applied. When that premise is broken, no matter how high the SPF (= estimated duration) is, it is a "treasure trove". This simple logic is often overlooked in today's market. [Explanation of background and premise] Navocal has a long-selling product that is not very noticeable. That is the sunscreen series. It was mainly sold at esthetic salons and medical clinics. The repeat rate of those who used it once was unusually high. This is because the adhesion is excellent, so I was able to experience it. [How to use] Shake the UV block up and down well before using it. Take an appropriate amount and blend it into your skin. After sweating or swimming, it is effective to reapply it. It can be removed with regular body soap.
