Green Slate Mineral Polish

Green Slate is a mineral-rich face polish that powerfully retexturizes and renews the appearance of dull, uneven skin. It uses a one-two punch of natural physical and chemical exfoliants to smooth and refresh skin's appearance for a bright, balanced, more even-textured complexion. Think of it as a deeply satisfying reset for your face — it buffs away dead skin, refines the look of pores, helps balance oil, and leaves you with a clean, comfortably balanced slate.

Green Slate combines two types of exfoliation in one step. Physical exfoliation comes from micro-fine particles like Volcanic Ash and Aluminum Oxide, which gently polish the skin's surface to smooth the look of texture. Chemical exfoliation comes from salicylic acid naturally found in Wintergreen and Willow Bark, which works below the surface to exfoliate and clarify the appearance of pores. Together, you get a more thorough and balanced exfoliation than either type alone.

Volcanic Ash (a natural physical exfoliant that gently retexturizes skin's appearance), Aluminum Oxide (micro-fine mineral crystals that provide a gentle polishing action), Wintergreen (a natural source of salicylic acid/BHA that helps refine the appearance of pores), Willow Bark (another natural chemical exfoliant that helps clarify the appearance of pores), Glacial Oceanic Clay (helps absorb excess oil and leaves skin feeling balanced), Birch Sap (helps hydrate and replenish skin so it isn't left feeling depleted), Meadowsweet Flower (supports smoother-looking, shine-free skin), and Lion's Mane Mushroom (a functional mushroom extract). The formula also includes Safflower Seed Oil, Sunflower Seed Oil, and Glycerin for nourishment. And as always: no petrochemicals, sulfates, parabens, synthetic fragrance or color, glycols, silicones, or PEGs.

Yes and yes! Green Slate Mineral Polish is 100% vegan, Leaping Bunny Certified cruelty-free, and gluten-free. Ursa Major is also a Certified B Corp and Certified Plastic Negative.

An invigorating, tree-topped scent of Fir and Cypress, with herbal notes of Ginger and Lavender—all from essential oils, never synthetic fragrance. It's refreshing and energizing.

Green Slate is formulated for all skin types, but it especially shines for congested or oily skin. If you deal with clogged pores, excess shine, or dull texture, this is your product. That said, customers with dry, normal, and combination skin also enjoy it as a weekly resurfacing treatment—the key is adjusting how often you use it.

Green Slate is a powerful exfoliating treatment that also replenishes skin, so it isn't left feeling dry or depleted. In a clinical study, 96% of participants agreed that their skin felt intact after use. That said, you know your skin best! If you're concerned, we recommend trying it out on your arm before using it on your face and limiting use to once a week. If you experience any irritation or redness, discontinue use until your skin has had time to recover.

No. Unlike harsh scrubs that strip skin, Green Slate is formulated with hydrating and replenishing ingredients like Birch Sap, Safflower Seed Oil, Sunflower Seed Oil, and Glycerin to ensure your skin feels balanced and nourished after use—not tight or depleted. The goal is a clean, fresh feeling without any dryness.

No—please avoid the eye area when using Green Slate. The physical and chemical exfoliants are too active for the delicate skin around the eyes. Keep it to the rest of the face, and if you want, the neck.

Gently massage a nickel-sized dab into damp skin, avoiding the eye area, then rinse thoroughly. That's it—no need to leave it on. The polish does its work during the massage, so take your time and enjoy the process. A little goes a long way.

We recommend starting with 1–2 times per week, polishing lightly to see how your skin responds. You can work up to 2–3 times per week depending on your skin's tolerance. We don't recommend using it more than three times per week. If you have sensitive skin, start with once per week.

Use Green Slate in place of your regular cleanser, 1–3 times per week. Follow with your toner, serum, and moisturizer as usual. It works great in the evening as part of your wind-down routine, or in the morning when you want to start the day with a fresh, polished slate.

Absolutely. Green Slate works wonderfully as a pre-shave face polish. By buffing away dead skin and clearing pores before you shave, you set the stage for a closer, smoother shave with fewer bumps and blemishes. It's especially popular with customers who deal with beard-related congestion.

In clinical testing after a single use, 100% of participants agreed their pores felt cleansed, 96% agreed their skin had a healthy glow, 96% agreed their skin looked and felt smoother, and 92% agreed the product balanced excess oiliness. Customers consistently describe a noticeably smoother, brighter complexion after the very first use.

Both. You'll feel (and see) a difference after the very first use—smoother texture, cleaner pores, fresher-looking skin. With consistent use over time (2–3 times per week), you'll also notice more sustained improvements in texture evenness, pore appearance, and overall radiance.

Green Slate is formulated for the face, but customers have successfully used it on rough patches like elbows, hands, and the neck area for the same smoothing and brightening benefits. Just avoid any broken or irritated skin.

The natural BHA from Wintergreen and Willow Bark can help keep pores clear, which is beneficial for acne-prone skin. However, if you have active breakouts or inflamed acne, we'd recommend being gentle—start with once a week, use light pressure, and see how your skin responds. Over-exfoliating inflamed skin can make things worse.

Everyone. Like all Ursa Major products, Green Slate is gender-neutral by design. It's especially popular with customers who shave their face, but the benefits of clearer pores, smoother texture, and brighter skin are universal.

Green Slate can be a great addition for teens (13+) dealing with oily or congested skin. We'd recommend starting with once per week and using light pressure, with a patch test first. For younger users, a gentler daily cleanser like Fantastic Face Wash is a better everyday starting point, with Green Slate as an occasional treatment.

Green Slate contains Wintergreen (a natural source of salicylic acid/BHA) and Willow Bark, which some healthcare providers recommend avoiding during pregnancy. We recommend discussing the ingredient list with your provider before use.

At 3.88 oz, Green Slate is a generous size. With 2–3 uses per week (a nickel-sized amount each time), most customers find a jar lasts 3–4 months. A little really does go a long way.

Green Slate comes in a glass jar. We're a Certified Plastic Negative company, meaning we fund the removal of twice as much plastic from the environment as we produce. We also offer a 30-day satisfaction guarantee with free returns.

Fantastic Face Wash is a daily cleanser — gentle enough to use morning and night, every day. Green Slate Mineral Polish is a treatment-level exfoliant designed for 1–3 times per week. They complement each other perfectly: Fantastic Face Wash for daily cleansing, Green Slate for deeper resurfacing when your skin needs a reset.

We'd recommend separating them. If you're using a serum with exfoliating actives (like the BHA in Brighten Up Vitamin C Serum or the Retinal in Lunar Bloom), avoid using Green Slate on the same day to prevent over-exfoliation. Alternate days—for example, Green Slate on Monday and Wednesday, and your exfoliating serum on the other days.
