Nidoki

Nidoki (二度置き) is a Japanese term used primarily in the context of cosmetic application, specifically referring to a method of applying and removing a cleansing product twice. The practice involves applying a cleanser (typically an oil-based cleanser), massaging it into the skin to dissolve makeup and impurities, rinsing it off, and then immediately repeating the process with the same or a different cleanser.

The perceived benefits of nidoki are thorough cleansing, ensuring all traces of makeup, sunscreen, and sebum are removed from the skin. Proponents believe that the first application removes the bulk of surface impurities, while the second application allows for a deeper cleanse, reaching pores and addressing remaining residue.

The necessity and effectiveness of nidoki are debated. Some dermatologists argue that double cleansing can strip the skin of its natural oils, leading to dryness, irritation, and a compromised skin barrier. Others maintain that it is a beneficial practice, particularly for individuals who wear heavy makeup or have oily skin.

The choice to implement nidoki in a skincare routine depends on individual skin type, sensitivity, and the types of products used. It is generally recommended to use gentle, hydrating cleansers and to carefully monitor the skin for any signs of over-cleansing or irritation.
