Who a clay mask suits
The AAD groups mask ingredients by skin type. For oily or acne-prone skin, it lists clay, like kaolin or bentonite, to help absorb oil and soothe irritation.
For dry or sensitive skin, the AAD points instead to hydrating ingredients such as hyaluronic acid, ceramides, glycerin and colloidal oatmeal. If your skin is dry, a hydrating mask is likely a better fit; see our hydrogel face mask guide.
The AAD is clear that masks cannot replace treatment for conditions such as acne or eczema; they are a boost alongside a regular routine.
Two clay masks compared
| Detail | The Ordinary Salicylic Acid 2% Masque | Innisfree Super Volcanic Pore Clay Mask |
|---|---|---|
| Clay and key ingredients | Kaolin, charcoal powder, salicylic acid | Volcanic clusters, AHA |
| Suited for | Oily skin | Excess sebum and visible pores |
| Exfoliating acid | Salicylic acid (BHA) | AHA |
| How often | Once or twice a week, ideally evening | Follow the label |
| Sizes or versions | 50ml, 100ml | Original, Cool Mint |
Details are from each maker's product page. The Ordinary says the clay and charcoal absorb facial impurities that would otherwise clog pores. Innisfree describes a wash-off, cooling clay mask that helps control excess sebum and visibly minimize pores while exfoliating.
How to use a clay mask
- Patch test first. The AAD suggests testing a new mask on a small area. The Ordinary advises applying its masque as directed to a small area once a day for three days before regular use.
- Start with clean, dry skin. The Ordinary says not to apply its masque to wet skin, and to spread it evenly with your fingertips.
- Watch the clock. The AAD says the label tells you how long to leave a mask on, and that leaving it on longer than intended or using it too often can cause irritation. The Ordinary says no more than 10 minutes.
- Rinse with lukewarm water, avoiding the eye area.
- Moisturize afterward. The AAD advises applying moisturizer after washing off a mask; see our facial moisturizer guide.
Ingredients to avoid
The AAD says to avoid masks with fragrance or essential oils, which may irritate or cause allergies; rubbing alcohol, which can dry out skin; and physical exfoliants such as walnut shells or apricot kernels, which can cause small tears. If you have sensitive skin, avoid strong exfoliating acids.
Both masks compared above contain an exfoliating acid. If you already use retinol or acid products, the AAD says to avoid masks with the same active ingredients to prevent irritation. See our retinol serum guide and exfoliating toner pads guide.
Sun and skin safety
Check whether your clay mask contains an acid. The Ordinary warns that its masque contains a BHA that may increase sensitivity to the sun and the chance of sunburn, and advises sunscreen, protective clothing and limited sun exposure while using it and for a week afterward. See our mineral sunscreen guide.
The Ordinary also says not to use its masque on sensitive, peeling or compromised skin, and to rinse off and see a physician right away for hives, swelling of the eyes or mouth, blistering, or difficulty breathing.
When to stop or see a dermatologist
Wash off a mask immediately if you feel itching, burning or stinging, which the AAD says could signal irritation or an allergy. An allergy to a mask ingredient can cause contact dermatitis. See a board-certified dermatologist if your skin feels worse after using a mask, or for acne that does not improve with over-the-counter care; see our acne spot treatment guide.
