Why It’s Special

Revives radiance

Dual-action exfoliation power and clarifying ingredients give skin a brightening boost to promote a refreshed, vibrant complexion.

Dramatically smoothes

Formulated with natural exfoliators like Volcanic Ash & Wintergreen for a strong, invigorating start and a soft, ultra-smooth finish.

Refines look of pores

Natural chemical exfoliators like salicylic acid found in Willow Bark work deep below the surface to cleanse and tighten the appearance of pores.

Balances things back out

Say so long to shine. This polish keeps excess oil in check, using actives like Oceanic Clay and Birch Sap to balance and hydrate skin.

    Q: Is this safe for sensitive skin?
    A: Green Slate Mineral Polish is a powerful exfoliating treatment that is designed to smooth skin’s appearance for your other skincare and makeup. That said, 88% of people who tried Green Slate in a consumer test agreed that their skin didn’t feel stripped after use, and 95% agreed their skin felt intact.


    Ultimately, you know your skin best. If you’re concerned about how your skin will tolerate Green Slate, we recommend trying it out on your neck or arm before using it on your face and limiting use to once a week. If you experience irritation or redness from any exfoliant, we recommend you discontinue use until that has subsided.


    Q:  What skin type is this suitable for?
    A: Green Slate Mineral Polish is appropriate for all skin types, especially congested or oily skin. 


    Q: Does this product remove makeup?
    A: This formula is optimized for exfoliation. We recommend one of our other cleansers (Fantastic Face Wash, Making Moves Milky Cleanser, or our Essential Face Wipes) if your main concern is removing makeup.


    Q: Will Green Slate Mineral Polish cause micro-tears?
    A: There’s currently no reliable way to evaluate whether a product causes micro-tears on the skin, but it’s true that any exfoliator (physical or chemical) can irritate the skin when used too frequently. We recommend using Green Slate Mineral Polish 1-2 times a week at first and polishing lightly to start. We don’t recommend using the product more than three times a week.


    Q: Is this product pregnancy safe?
    A: Green Slate Mineral Polish contains a small amount of natural salicylates from the Wintergreen and Willow Bark. Some doctors recommend against those during pregnancy. This is a wash-off product, so risk is lower, but we always recommend checking with your doctor before incorporating a new product.


    Q: How do I recycle this product?
    A: When you run out, just give the glass jar a rinse and recycle it at home. The lid is not widely recyclable at this time.


    Q: What is the aroma?
    A: An invigorating, tree-topped scent of Fir and Cypress, with herbal notes of Ginger and Lavender.

      Perfect!!

      I've tried a lot of exfoliators over the years and this one beats all. You can feel it working...gritty WITHOUT irritation or redness. It rinses so easily and leaves ZERO residue...and ZERO dryness or tightness. My face is soft and healthy looking after. Absolutely no complaints, I'm a lifer with this stuff. Maybe a body wash like Green Slate in the future?! Thank you for nailing it, Ursa Major!

      Love This!

      Love this exfoliating polish. I use it every other day and it leaves my skin vibrant and clear. I love the way my face feels moisturized after using in the shower. This is the first mineral exfoliator I have ever used that didn't clog my pores. I love the scent, it make me feel like I just had a facial.
