History of clay use
Clay is one of humanity’s oldest natural remedies and beauty ingredients, with traces of use dating back thousands of years. It has been valued as a cleansing, healing, and cosmetic substance.
Mediterranean lands
In the Mediterranean, Greeks and Romans used clay both for body care and medical purposes. Hippocrates, known as the father of medicine, described clay’s cleansing and anti-inflammatory properties. In the Roman Empire, clay was a key part of the thermal bath tradition, used for cleansing the skin, relieving joint ailments, and supporting general well-being. Clay was also valued for its ability to absorb toxins and waste products, and was even taken internally for digestive issues.
Egypt
In ancient Egypt, clay was widely used in medicine, cosmetics, and mummification. Papyrus scrolls reveal recipes where clay was mixed with oils and herbs to treat wounds, skin diseases, and inflammation. Pharaohs and nobility are known to have used clay masks to maintain radiant, youthful skin. Clay was also added during embalming processes, as it helped remove moisture and slow decomposition.
The Orient
In the East – especially Mesopotamia, India, and China – clay also played an important role. Evidence from Mesopotamian temple springs shows clay used in healing rituals and daily health practices. In Ayurvedic medicine, clay is described as a natural balancer, helping to cool and cleanse the body. In Traditional Chinese Medicine, clay was used both internally and externally – for calming the stomach and alleviating skin rashes.
The power of clay – properties
Clay minerals have become an integral part of natural cosmetics, valued for their mineral-rich composition that supports skin health and beauty. But what makes these minerals so effective for our skin?
Properties and benefits of clay
Clay is much more than just a cosmetic ingredient. Known for its exfoliating and soothing properties, it is especially popular for its remarkable absorption and adsorption abilities.
Before looking at these beneficial properties more closely, it’s important to distinguish between absorption and adsorption:
-
Absorption occurs when a liquid penetrates the pores or structure of a material, much like a sponge soaking up water.
-
Adsorption, however, means that the liquid binds to the surface of a material without entering its structure.
Main benefits of clay minerals
-
Deep cleansing – clay is a gentle yet effective exfoliant. Its fine texture removes dead skin cells, leaving the skin smoother and more radiant.
-
Adsorptive power – thanks to its charged surface, clay attracts and binds toxins, bacteria, and impurities. Acting like a magnet, it purifies the skin and reveals natural radiance, making it ideal in purifying masks and deep cleansers.
-
Absorptive power – clay has an impressive ability to soak up excess moisture and sebum. Applied to the skin, it absorbs excess oil and dirt, leaving the skin clean, fresh, and balanced.
-
Remineralization – clay is rich in essential minerals and trace elements such as calcium, potassium, magnesium, and iron. These nourish the skin and support its health.
-
Hair benefits – clay minerals are not only for the skin – they are excellent in hair care as well. Clay absorbs excess oil and removes impurities from the scalp, regulating sebum production and helping to combat oily hair and dandruff.
Clay is much more than just a cosmetic ingredient. Its exfoliating, adsorptive, and absorptive properties make it a natural and effective solution for supporting the health and beauty of both skin and hair. Whether the goal is to purify pores, balance oily skin, or simply enjoy a moment of relaxation – clay is an indispensable part of your beauty routine.

How to use clay – Les Argiles Du Soleil recommendations
Beauty mask with clay
Pour the clay powder into a non-metallic bowl, add liquid (spring water, filtered water, floral water, herbal tea…) in the ratio of one tablespoon of clay to 1.5 times that amount of water. Let the mixture absorb naturally, then stir gently with a wooden spoon until you obtain a smooth and creamy paste. If the paste is too thick, add more liquid; if too runny, add more clay.
Green clay – Les Argiles du Soleil
Apply a thick layer to clean skin with hands or a brush, avoiding the eyes and lips. Leave for about 10 minutes, keeping the mask moist if it dries too quickly. Rinse thoroughly with water and follow with your usual moisturizer.
Hair care with clay
(Recommended clays: Ventoux green montmorillonite, Rassali, Bonneval illite, Auban yellow)
Moisten the hair, apply two tablespoons of clay paste to the scalp and massage gently. Add water if needed. Leave for about 10 minutes, then rinse thoroughly. This detox mask is suitable for all hair types and is ideal before applying plant-based hair dye.
Hairdresser’s tip: Mix 1–2 tablespoons of clay into your shampoo (preferably neutral). Massage into hair, leave for at least 5 minutes, then rinse.
Dry shampoo (Rassali clay):
Apply Rassali clay to the hair with a large brush, as close to the roots as possible. Massage gently into the scalp, then brush out the excess clay. The hair becomes refreshed and more voluminous.
Wraps and compresses with clay
Use a glass container (avoid metal and plastic). Fill half to three-quarters with Ventoux montmorillonite clay. Add water so that the clay is covered by 0.5–1 cm. Let it absorb naturally, do not stir, as this may reduce absorbency.
Preparation takes from a few hours up to half a day. You can prepare it the day before. The paste should be thick, but not too hard or too runny. Add water or clay powder if necessary.
Apply a 1–2 cm layer to the affected area and cover with cloth. Leave on for 1–2 hours and remove before drying. Clay wraps are not reused – discard after use.
Clay bath
Clay can be combined with different plants. After a long day, prepare a soothing bath: put 300 g of Auban yellow clay into a muslin bag, add a handful of seaweed powder, thyme and rosemary (fresh or dried). Soak in warm bath water (38–39 °C) for 20 minutes and enjoy.
Hand wash with clay
For gentle hand washing, mix a little Izane white clay with water, rub onto hands and rinse. Hands will be clean and soft – perfect for hiking and outdoor activities.
Coloring soaps and beauty products with clay
Clays are insoluble and can be added during the "trace" stage of soap making, either directly or pre-mixed with a small amount of vegetable oil.
-
Sift the clay with a fine sieve.
-
Mix with oil (1 part clay : 4 parts oil).
-
Whisk with a whisk or mixer.
-
Add early to the soap mixture.
Clays do not react with lye and do not affect soap curing.
Homemade clay cleaning stone
Ingredients:
-
50 g Izane white clay
-
50 g baking soda
-
25 g liquid Marseille soap
Mix the clay and baking soda with a wooden spoon, add liquid soap and blend into a paste. Place in a container and let dry for 1–2 weeks. After each use, allow to dry before closing.
Compatibility of clay and oil
Clays (like green clay, white kaolin, pink clay, rhassoul) are naturally absorbent and cleansing — they draw out excess sebum, impurities, and pollution from the skin.
Oils (like jojoba, apricot kernel, grapeseed, or argan oil) are emollient and nourishing — they help soften and protect the skin.
When you combine the two, you create a balanced treatment that cleanses without drying, leaving the skin soft, calm, and refreshed.
1. Gentle mask for dry or sensitive skin
-
1 tsp plant oil (jojoba, sweet almond, or argan oil)
-
A few drops of water or floral water until you get a creamy paste
→ Apply to the face for 10–15 minutes (don’t let it fully dry!) and rinse with lukewarm water.
Tip: If the mask starts drying too fast, mist your face with floral water (like rose water) to keep it slightly moist.
2. Cleansing clay–oil paste (for gentle deep cleaning)
-
Mix equal parts clay and oil (for example, rhassoul + grapeseed oil)
-
Massage onto damp skin in circular motions
-
Rinse with warm water or remove using a damp cloth
This method works beautifully for combination, oily, or sensitive skin types that need deep cleansing without irritation.
Things to keep in mind
-
If you mix only oil and clay (without water), you’ll get a thicker, creamier texture — great for a cleansing paste, not for a drying mask.
-
If you want that classic clay mask effect, always add some water or hydrosol, since clay activates in contact with water.
-
Avoid metal bowls or spoons — clays can react with metals. Use glass, ceramic, or wood instead.
Clay care tips
-
Alternate between different clays to maximize benefits.
-
Always perform a patch test (inner forearm).
-
For dry or sensitive skin, use clay masks at most once a week.
-
Cleanse the skin before applying the mask.
-
Always moisturize after a mask (cream or face oil).
What NOT to do with clay
- Do not heat clay (stove, oven, microwave) – dry in the sun.
- Do not use metal tools – they can oxidize and reduce effectiveness.
- Do not use plastic – prefer glass, ceramic, or wood.
- Use spring water, not tap water (which contains chlorine and nitrates).
- Be careful, clay may stain clothes.
- Do not mix clay with essential oils or medicines unless you understand their effects.
- Do not let clay dry completely on the skin – moisture is key to its effectiveness.
- Do not apply clay to heated or medicated skin.
Storage
Keep clay in its original packaging in a dry, well-ventilated place, away from moisture and dirt. Close the bag properly after each use (a wooden clip works well).
