"Alguard Clear Block Z" is formulated with a focus on a pleasant feel, blending cooling agents such as "L-menthol" and "d-camphor" in an exquisite balance. L-menthol, in particular, is essential when discussing the pleasant feeling of application. The moment you apply it, it releases a refreshing scent as it flows through the tear ducts towards the nose along with the tears. Even within the category of L-menthol, there are differences in origin, refinement level, and scent, and the application experience changes completely depending on which one you choose.

Furthermore, the unique feel of Rohto Pharmaceutical's product is achieved not only through L-menthol alone, but also through its interaction with d-camphor and other ingredients, as well as the ingenious combination of ingredients.
