Clays are some of the most time-tested ingredients in skincare. Used across cultures for centuries, these mineral-rich earth materials gently cleanse, balance, and refine the skin—without relying on harsh actives. At Sealed by Nature, clays are valued not for aggressive “detox,” but for their ability to support healthy skin through thoughtful, balanced formulation.
Benefits of Clays in Cosmetics
Cosmetic clays work through physical absorption, not chemical exfoliation. Their unique mineral structures allow them to attract excess oil and impurities while remaining gentle on the skin barrier.
Key benefits include:
- Absorbing excess oil and impurities
- Gently refining skin texture
- Calming irritation and redness
- Supporting a balanced, matte finish
- Enhancing texture and stability in formulations
When used correctly, clays cleanse without stripping and prepare the skin to better receive nourishing oils, butters, and botanicals.
Types of Cosmetic Clays & Their Differences
White Kaolin Clay (Gentle & Soothing)
The mildest cosmetic clay, white kaolin is ideal for sensitive, dry, or mature skin.
- Light oil absorption
- Soft, silky skin feel
- Suitable for frequent use
Commonly used in facial masks, cleansers, soaps, and powders.
Pink Kaolin Clay (Balancing & Brightening)
A natural blend of white and red kaolin, pink kaolin offers gentle cleansing with a touch more vitality.
Mild absorption
Improves appearance of dull skin
Naturally blush-toned color
Often chosen for masks, soaps, and body products.
Green Clay / French Green Clay (Clarifying)
Rich in minerals and highly absorbent, green clay is best suited for oily or congested skin.
Strong oil absorption
Pore-refining feel
Ideal for occasional deep cleansing
Typically used in detox masks and clarifying soaps.
Bentonite Clay (Deep Cleansing)
Formed from volcanic ash, bentonite expands when hydrated, helping lift impurities from the skin.
Very high absorption
Best for oily skin and scalp treatments
Use in moderation
Often found in acne masks, deodorants, and scalp products.
Clay vs. Charcoal vs. Diatomaceous Earth
Activated Charcoal
Extremely porous
Strong odor and impurity adsorption
Can be drying if overused
Diatomaceous Earth (Cosmetic Grade)
Made from fossilized algae
More exfoliating than clays
Adds structure and slip to products
While often grouped together, these ingredients behave differently and are chosen intentionally based on the product’s purpose.

How to Choose the Right Clay for Your Skin
- Dry or sensitive skin: White or pink kaolin
