A clay or mud mask is, of all the things that fall under the heading of facial procedures, the one with the lowest barrier to entry and the highest reliability. You mix powdered clay with water. You spread it on your face. You wait twenty minutes. You rinse it off. The face is cleaner, tighter in the good way, and more responsive for the next day or two. That is the whole procedure.
I do this maybe twice a month. Some weeks once. Some weeks not at all. The frequency depends on what the skin has been doing — a week of poor sleep and bad food usually earns the skin a mask the following weekend. A clean run usually does not.
The three clays worth knowing
Green clay. The strongest of the three. It absorbs oil and surface impurity aggressively, and it is the right choice for skin that is oilier, congested, or recovering from a stretch of being neglected. Apply for ten to fifteen minutes only — longer and it dries the skin out. This is the clay most people should use most rarely.

Pink clay. The middle of the three. A mix of red and white clays, gentler than green but still effective. This is what I use most often. It absorbs less aggressively and can be left on longer — twenty minutes is comfortable — without stripping. It suits most skin types most of the time.
White kaolin. The gentlest. Suits sensitive, thin, or reactive skin. Can be left on for thirty minutes if you want. It does less than the other two but it is the safest choice for skin that does not tolerate the stronger options.
How to mix and apply
Two tablespoons of clay powder. Add water — or, for a slightly more nourishing version, the same volume of a herbal tea (chamomile, green tea) cooled to lukewarm — until the texture is that of soft yoghurt. Mix in a small ceramic or glass bowl. Avoid metal bowls; some clays react slightly with metal.
Apply to clean dry skin with a flat brush or with fingers. Avoid the eye area and the immediate area around the lips. The layer should be thick enough that you cannot see skin through it — too thin a layer dries too fast and produces no useful work.
The waiting
Twenty minutes for pink, fifteen for green, thirty for white. Some part of the mask will dry hard and crack toward the end. This is fine. Do not let it dry to the point where it pulls uncomfortably on the skin — that means you waited too long.
Rinse in lukewarm water using gentle circular motions. Do not rub. The clay should come off easily; if it is sticking, splash water on the face for a minute first to soften it. Pat dry. Apply a hydrating toner and a moisturiser to the still-damp skin.
What not to do
Do not use a clay mask more than once a week. The skin needs time to recover its natural oil balance between treatments. Twice a month is plenty for most people.
Do not use one on broken or actively inflamed skin. The clay will worsen both.
Do not buy expensive masks. Plain cosmetic clay powder from a herb shop, mixed with water, performs as well as almost any branded version that costs ten times as much.
A clay mask is twenty minutes of being elsewhere, with the face being elsewhere too. That is most of what makes it useful.
