The versatility of clay has made it a mainstay in DIY beauty recipes—both now and in ancient cultures [source]. Clay has been used for medicinal purposes such as detoxifying the body and easing digestive issues [source], but today we are going to focus on the therapeutic and cosmetic benefits for skin.
What is clay?
Clay is a naturally occurring substance rich in minerals like magnesium, calcium, iron, silica, and potassium [source], and it can be found in volcanic ash, sediment, and soil. Clay can be found in a number of products, from cleansers to face masks to athlete’s foot treatments.
What are the benefits of clay for skin?
Depending on the type of clay you use, clay masks can help pull out impurities from inside pores to treat acne [source], heal allergic skin reactions, ease the effects of sunburn, boost elasticity, and balance oil production. Clay has been shown to increase collagen production, which strengthens the structure underlying the skin [source].
It also has detoxifying properties that draw out impurities such as bacteria, viruses, toxins, and fungi. Some clays contain over 50 minerals! Just be sure never to use metal containers, spoons, or lids when storing or using clay as the metal will interfere with the clay’s efficacy. Instead, use glass or wooden bowls and spoons.
What’s the right clay for my skin type?
Oily or Acne Prone
White Kaolin Clay is a very fine and light clay, mostly made up of the mineral kaolinite, and is common in many cosmetic products. Moroccan Red Clay is mined in the mountains of Morocco and deeply cleanses the pores while stimulating circulation, yet it’s still gentle enough for sensitive skin.
Normal to Oily
Bentonite Clay, formed from volcanic ash, is the most widely used clay and perfect if you aren’t quite sure which clay is right for you. It can absorb excess oil and tighten skin simultaneously.
Bentonite Clay also has healing properties internally and is often used to treat digestive issues [source]. Named from a large deposit found in Fort Benton, Wyoming [source], this clay can definitely serve double duty in your medicine cabinet. Bentonite clay’s properties not only draw out the skin’s impurities but also transfer the minerals to your skin in their place.
Sensitive or Reactive
French Green Clay, quarried originally in Southern France and then discovered elsewhere, is both detoxifying and healing. It’s an illite clay that is known to remove metals, and it gets its green color from kelp and algae.
If your skin is suffering from a sunburn, allergic reaction, or a wound, this sea clay is the right choice due to its antibacterial [source] and anti-inflammatory properties believed to come from the plant matter in the clay [source].
A sedimentary clay, Fuller’s Earth has lightening properties for pigmented and aging skin. Due to its strength, Fuller’s Earth can be combined with small amounts of Bentonite Clay.
Receiving its name from textile workers named “Fullers,” who used this clay to remove oil from wool, this has become a choice clay for drawing out excess sebum and decolorizing (lightening) oil out of pores.
Rhassoul (or Ghassoul) Clay, not to be confused with Moroccan Red Clay, is rich in potassium, magnesium, calcium, and sodium. Mined in Eastern Morocco, Rhassoul Clay is found to have higher percentages of magnesium and silica, making it silky smooth and the first choice for luxury spa treatments.
For skin that is losing elasticity and needs deep exfoliation, Rhassoul Clay is the perfect ingredient to firm and revitalize. This clay is the most hydrating of the clays discussed here, as it swells when water is added, helping the skin retain moisture.
Easy Clay Mask Recipe for Any Skin Type
Once you’ve determined the right clay for your skin, you’re halfway there. Mix equal parts clay with any of these options, typically 1–2 tablespoons is ideal for a one-time use mask:
Sensitive Skin – plain yogurt, water, or cooled chamomile tea. You can mix and match any or all of these into clay for a soothing mask.
Apply your clay mask for approximately 10 minutes, and then remove with warm water. Follow with your normal skincare routine.
