How often should I use this clay, and how can I tell if I am overusing it? — Siberian clay, toning phytocosmetic 155ml

There is no single schedule for everyone, but the product description presents this type of clay as a deeper cleansing step used “a few times per week.” A sensible way to start is one face mask per week, and only add a second or third session if the skin stays comfortable. Use face, hair, and body masks on different days rather than all at once.

The clearest signs of overuse are changes you can feel: a tight, squeaky sensation that does not disappear within half an hour, flaky patches, redness, or a stinging feeling when you apply moisturiser. These are signals to reduce the frequency, shorten the mask time, or switch to a gentler, more hydrating routine. A brief flush after rinsing can be normal with an active clay, but it should fade quickly. If it lingers or intensifies, stop using the product.

Another practical point: oily skin does not need to be stripped completely to look less shiny. If you over-cleanse, the skin often compensates by producing more oil, creating a cycle of excess. Keeping the mask moist rather than leaving it until it cracks, and following each session with a moisturiser, are the simplest ways to avoid this.

For the hair, a reasonable starting point is once a week; if the scalp feels dry or itchy, pause and reduce the frequency. For body wraps, start with one session, wait a day or two to observe how the skin reacts, then adjust. Your own skin response is a more reliable guide than any fixed weekly number.
