Why does my skin turn red and tingle after using this gel, and is that normal?

The key component is freshwater sponge powder, known as badyaga. Its very fine natural silica needles gently stimulate the surface of the skin, which increases local microcirculation in the treated area.

That mechanism is why the skin may become red and feel active, warm or tingling for a while after application. It is a local response to the ingredient, not a sign that the product is damaged or incorrectly used, as long as the skin is unbroken and the sensation stays within a tolerable level.

The effect is temporary and tied to short-contact use: the gel is applied locally, left on briefly, and then rinsed off. If the burning sensation feels too strong, or if redness turns into persistent irritation after washing, discontinue use and avoid reapplying to that area.

If you have reactive skin, test a very small amount first before covering a larger area. Avoid eyes and mucous membranes, since the same stimulating action can be uncomfortable on sensitive surfaces.
