Category: [Face masks](https://lovi.care/skincare/ca/best/face-masks)

This fit is calculated for the concerns frequently associated with acne-prone skin: breakouts, blackheads, and post-acne marks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for acne-prone skin; other cleansing masks fit it better.

## Why this fit

- Offers moderate suitability for your combination skin as kaolin and bentonite effectively absorb excess oil and impurities, helping to cleanse pores and reduce blemishes. Aloe barbadensis leaf juice and oat kernel flour provide some soothing benefits, though more targeted acne-fighting ingredients would enhance its effectiveness for your primary concerns.
- The formula is generally safe for your acne-prone skin, with no harsh or irritating ingredients identified.
- It provides excellent pore cleansing and oil absorption, aligning well with your combination skin type.

([Skin Research and Technology, 2024](https://pubmed.ncbi.nlm.nih.gov/38591218/))
- Twice-weekly use of a clay mask over 4 weeks in 75 adults with oily or combination skin improved acne-related outcomes, sebum content, skin evenness, hydration, and reduced dryness and irritation. ([Skin Research and Technology, 2023](https://pubmed.ncbi.nlm.nih.gov/38009030/))
- Clay jojoba oil facial masks reduced total skin lesions by a mean of 54% after 6 weeks in 133 participants with acne-prone, lesioned skin and mild acne compared to baseline. ([Forschende Komplementarmedizin, 2012](https://pubmed.ncbi.nlm.nih.gov/22585103/))
- Quaternized carboxymethyl chitosan/organic montmorillonite nanocomposite demonstrated superior moisture-adsorption and retention compared to hyaluronic acid, good UV-protection ability, negligible dermal irritation, and prominent moisture-retention efficacy on human stratum corneum when formulated into a cosmetic cream. ([Carbohydrate Polymers, 2017](https://pubmed.ncbi.nlm.nih.gov/28732847/))
- A novel water-in-oil emulsion with a lecithin-modified bentonite prevented epidermal degradation and inflammatory protein secretion induced by urban dust and cedar pollen more effectively than a conventional water-in-oil emulsion in a reconstructed human epidermis model. ([International Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/31995229/))
- Bentonite nanoparticles and honey co-administration improved skin wound healing in BALB/c mice by reducing inflammatory cell infiltration and increasing fibroblastosis, new epithelium thickness, granulation area, and collagen density compared to the untreated control group.

## Questions and answers

### How well does Kiehl's Rare Earth Mask work for acne-prone skin?

This mask offers an average fit for your acne-prone skin because its clays absorb excess oil and impurities, though other products fit it better by including targeted acne-fighting ingredients like salicylic acid and zinc oxide to better handle blemishes.

### Which ingredients make this mask a good fit for acne-prone skin?

Kaolin and bentonite help absorb excess oil and impurities to cleanse pores, while aloe barbadensis leaf juice and oat kernel flour provide soothing benefits for acne-prone skin. A product of this type needs targeted acne-fighting ingredients like salicylic acid or zinc oxide to better manage blemishes.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/41347526/), [Clinical Pharmacology, 2018](https://pubmed.ncbi.nlm.nih.gov/30588129/)

### What does Amazonian White Clay do for acne-prone skin?

Amazonian White Clay helps clear impurities and control excess oil on acne-prone skin, making it look much smoother and less greasy. This type of clay needs strong oil-absorbing minerals and gentle purifying ingredients to deeply clean pores without causing irritation.

### What does Kaolin Clay do for acne-prone skin?

Kaolin clay helps absorb excess oil and calms redness in acne-prone skin with a strong safety profile. Using a clay mask twice a week may improve acne and skin evenness while keeping dryness under control.
Sources: [Skin Research and Technology, 2023](https://pubmed.ncbi.nlm.nih.gov/38009030/), [Archives of Dermatological Research, 2024](https://pubmed.ncbi.nlm.nih.gov/39438324/)

### Where does this mask go in a skincare routine for acne-prone skin?

This cleansing mask fits into your weekly routine as a step after your cleanser and enzyme powder, and before your hydrating toner and moisturizer. It helps absorb excess oil and impurities, though acne-prone skin also benefits from targeted acne-fighting ingredients.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/41347526/), [Clinical Pharmacology, 2018](https://pubmed.ncbi.nlm.nih.gov/30588129/)

### Can I use this mask with retinol, and in what order?

You can use this cleansing mask in your weekly routine, but avoid applying it on the same nights you use retinol to prevent irritation. Instead, use the mask on a separate evening, or keep retinol for your nightly routine and use this mask just once a week as an extra step.

### How often should I use this mask?

You can use this mask once a week as part of your weekly routine. It effectively absorbs excess oil and impurities with clays while soothing the skin, though acne-prone skin often benefits from adding more targeted acne-fighting ingredients.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/41347526/)

### Can this mask clog pores, cause breakouts or purging for acne-prone skin?

This mask is generally safe for acne-prone skin and is unlikely to clog pores, as its clays absorb excess oil and impurities. However, some users may experience mild stinging or redness, and a product of this type needs stronger acne-fighting ingredients to better prevent breakouts.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/41347526/), [Clinical Pharmacology, 2018](https://pubmed.ncbi.nlm.nih.gov/30588129/)

### Is this mask fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
