What is French Green Clay and How to use it?

What is French Green Clay?

French green clay is a type of mineral-rich clay that is known for its various uses, particularly in skincare and beauty products. It is a fine, pale green powder that is made up of iron oxides, kelp, and other decomposed plant matter.

These natural minerals were first mined on the southern coasts of France, where most of the world’s deposits were found, hence the name “French green clay.”

Uses of French green clay

It has a variety of uses, both internally and externally. However, it’s important to note that the scientific evidence supporting some of these claims is limited.

Here are some of the most common uses:

1. Face masks.

Green clay is a popular ingredient in face masks due to its supposed ability to absorb oil, remove impurities, and exfoliate dead skin cells. This can help to improve the appearance of oily skin, acne-prone skin, and large pores.

2. Body wraps.

It can also be used in body wraps to help detoxify the skin and improve circulation.

3. Hair masks.

Some people use them as a hair mask to help remove product buildup and add shine to the hair.

4. Poultices.

It can be mixed with water to create a poultice, which can be applied to the skin to help reduce inflammation and soothe pain.

5. Digestive health.

Some people believe that it can help to improve digestive health by absorbing toxins and impurities from the gut. However, there is no scientific evidence to support this.

6. Detoxification.

French green clay is sometimes used as a detoxifying agent. However, there is no scientific evidence to support the claim that it can remove toxins from the body.

Benefits of French green clay

French green clay has been used for centuries for various purposes, and many potential benefits are attributed to it. However, it’s important to understand the current state of evidence and approach these claims with caution. Here are some of the benefits:


  1. Oil absorption and impurity removal: Absorbent properties may help reduce excess oil and cleanse pores, potentially beneficial for oily and acne-prone skin. Some studies suggest effectiveness in absorbing toxins, but more research is needed.
  2. Exfoliation: The fine texture may help remove dead skin cells, promoting smoother skin. However, be gentle as overuse can irritate.
  3. Inflammation reduction: Some studies suggest potential anti-inflammatory properties, but more research is needed to confirm and understand the mechanism.
  4. Improved circulation: Clay masks may temporarily improve blood flow due to tightening and warming effects, but long-term benefits are unclear.
  5. Wound healing: Some studies suggest potential benefits for wound healing, but more research is needed to understand the mechanism and confirm its effectiveness.

Other uses:

  1. Hair care: May add volume and shine, but the evidence is limited and its effectiveness compared to other options is unclear.
  2. Insect bites and stings: May help reduce swelling and itching, but more research is needed to confirm and understand the mechanism.
  3. Sunburns: May soothe and heal sunburns, but the evidence is limited and its effectiveness compared to other options is unclear.
  4. Digestive issues and detoxification: While some believe it can improve digestion and remove toxins, there is limited scientific evidence to support these claims.

How to apply French green clay on the skin and how often?

Here’s how to apply French green clay on the skin and how often you should use it:

How to prepare:

  • Things you need: You’ll need French green clay powder, a non-metallic bowl or spoon, water or another liquid (like rosewater or apple cider vinegar), and a face mask brush (optional).
  • Patch test: Before applying to your entire face, do a patch test on a small area like your inner forearm. Apply a small amount of the clay paste and leave it on for 10-15 minutes. Rinse it off and wait 24 hours to see if any irritation occurs. If not, you can proceed with the full application.

How to use:

  • Cleanse your skin: Remove all makeup and impurities with a gentle cleanser. Pat your face dry.
  • Mix the clay: In your bowl, mix the clay powder with water or your chosen liquid to create a smooth paste.
  • Apply the mask: Use your fingers or a brush to apply a thin layer of the paste to your face, avoiding the delicate areas around your eyes and lips. You can apply it all over.
  • Relax and wait: Leave the mask on for 10-15 minutes, or until it dries slightly and feels tight. Don’t let it dry completely, as this can be too harsh on your skin.
  • Rinse and moisturize: Gently rinse the mask off with lukewarm water. Dry your face and apply a moisturizer.

How often to use it?

  • For oily or acne-prone skin: You can use a French green clay mask 1-2 times per week.
  • For normal or combination skin: Use it once a week or every other week.
  • For dry or sensitive skin: Use it sparingly, like once every two weeks or even less frequently.

Additional tips:

  1. Don’t use metal utensils with the clay, as it can react and reduce its effectiveness.
  2. You can customize your mask by adding other beneficial ingredients like honey, yogurt, or essential oils (suitable for skin use).
  3. Always store leftover clay powder in an airtight container in a cool, dry place.

Remember, while French green clay has potential benefits, it’s not a miracle cure. Be consistent with your skincare routine and manage your expectations based on the current scientific evidence.

Risks of French Green Clay

While some use French Green Clay internally for digestive issues or detoxification, it’s crucial to understand the significant risks and limited evidence supporting these practices.

  • Constipation: Clay’s absorbent nature can block the intestines, leading to constipation and discomfort.
  • Nutrient interference: It may bind to essential minerals like iron and potassium, hindering their absorption.

While generally considered safe for external use, French Green Clay can still cause some side effects, especially with sensitive skin or improper application.

  • Skin irritation and dryness: Clay’s absorbent nature can dry out the skin, and overuse or leaving it on for too long can lead to irritation, redness, or itching.
  • Allergic reactions: Though uncommon, some individuals might experience allergic reactions like rashes or swelling.

Green clay vs. Bentonite clay

Both French green clay and bentonite clay are popular natural clays used for skincare and other purposes, but they have some key differences.

Here are the key differences:

Basis of DifferenceGreen ClayBentonite Clay
OriginIt is mined from natural deposits in France and other regions worldwide. Its green color comes from decomposed plant matter and iron oxides.It is formed from volcanic ash deposits. It has a gray or cream color due to various minerals like aluminum silicate.
CompositionContains minerals like calcium, potassium, magnesium, and iron.Rich in aluminum silicate, calcium, magnesium, sodium, and iron.
PropertiesHighly absorbent, draws out oils and impurities, suitable for oily and acne-prone skin. May have some anti-inflammatory and wound-healing properties.Very absorbent, known for its detoxifying properties, suitable for various skin types. May help reduce inflammation and absorb impurities.
Other usesHair masks, insect bites, sunburns (limited evidence).Very absorbent, known for its detoxifying properties, and suitable for various skin types. May help reduce inflammation and absorb impurities.

Which one to choose:

  1. For oily skin: Both can be effective, but bentonite clay’s high absorption might be better. Use cautiously and moisturize afterward.
  2. For sensitive skin: French green clay is generally gentler.
  3. For specific concerns: Consider the specific properties of each clay for your needs (e.g., bentonite for inflammation, French green for gentle exfoliation).

The Bottom Line

French green clay holds potential appeal for skincare enthusiasts with its purported benefits like oil absorption, gentle exfoliation, and even anti-inflammatory properties. However, while some studies show promise, the evidence for these claims remains limited.

Remember, even external use can cause dryness or irritation, especially with sensitive skin. Consult a dermatologist for personalized advice. Always perform a patch test before diving in.

Remember there’s no magic bullet for achieving healthy, vibrant skin.
