Detox: What Your Skin Really Needs
Your body is the detox system
Juice cleanses, detox teas and fasting programmes promise to flush out toxins. But when researchers reviewed the evidence, they found no compelling support for detox diets removing toxins – and no rigorous clinical studies behind them. Most commercial programmes don’t even say which toxins they target.
Your body already has a highly sophisticated system for this: the liver, kidneys, gut and lungs work around the clock. Extreme fasting can instead lead to nutrient deficiencies. The best “detox” for your skin is to support that system with good food, water and sleep.
A clean start
For your skin, detox is really about cleansing. Every day it collects sebum, sweat, dead skin cells, sunscreen and particles from the air – and a gentle cleanse removes them without stripping the barrier. In the Moroccan hammam, this has been done for centuries with hammam black soap and rhassoul clay.
Clay masks do something real, but temporary: in a 2025 study, red, green and black clay masks clearly reduced surface oil right after use, but sebum levels were back within two hours, and there was no firming effect. So think of green clay or rhassoul clay as a weekly deep clean – not a permanent change.
Heat and the sauna
In the Nordic countries, the sauna has been part of life for generations. Research suggests it may be good for the skin too: in a controlled study, people who took regular saunas had a more stable skin barrier and a better ability to hold water in the outer layer of the skin, and their skin recovered its hydration and pH faster after a session.
Heat and cleansing can leave skin feeling tight, so finish with a cool floral water and a few drops of oil. A black soap wash before the sauna is a classic.
Trend check
| The promise | What we know | |
|---|---|---|
| Juice cleanses | Flush out toxins | No rigorous evidence – your liver and kidneys already do this job |
| Detox teas | Clear, glowing skin | No compelling evidence that detox products remove toxins |
| Clay masks | Pull toxins out of the skin | Absorb surface oil for a few hours – a real but temporary deep clean |
| Regular sauna | Sweat it all out | Linked with a more stable skin barrier and better hydration |
