Use it as a regular body wash: wet your skin in the shower, pour a small amount into your hand or onto a washcloth or loofah, work it into a lather, and massage over the body. Rinse thoroughly. A 400 ml bottle lasts a long time if you start with a coin-sized amount; you can always add more if you want a richer lather.
Because the formula contains mint and menthol, it is best suited to moments when you want to feel awake: first thing in the morning, after a workout, or on hot, humid days. If you prefer a gentler experience, use it only on the torso and limbs and use a milder, fragrance-free cleanser for the underarms and intimate areas. Avoid using it on the face, as facial skin is thinner and more reactive to cooling ingredients.
For very dry skin, the order matters: use the gel, rinse, then apply a body lotion or body oil while the skin is still damp to lock in moisture. In winter, or if you shower more than once a day, consider alternating this gel with a cream-based or more moisturising body wash so your skin does not become dry.
Store the bottle upright with the cap closed, away from direct sunlight and heat. If the gel gets into your eyes, rinse them with plenty of clean water.
