CLEARSTEM Sulfur Spot & Mask — Dual-Purpose Acne Face Mask, Kaolin Clay & Glycolic Acid

CLEARSTEM SULFUR SPOT & MASK is a dual-purpose clay mask and targeted sulfur spot treatment formulated to reduce visible congestion, control excess oil, and smooth skin texture.

This multi-functional formula combines sulfur, kaolin clay, and glycolic acid to clarify pores, gently slough away surface buildup, and help reveal a more even-looking complexion when used as part of a regular skincare routine. Designed to be used either as a full-face weekly treatment or applied directly to blemish-prone areas, the product adapts to varied skin needs while pairing well with standard cleansers.

How should I use this mask in my weekly routine?

Apply a thin, even layer to clean, dry skin and leave on for the recommended time before rinsing. For weekly care, use it as a full-face mask to draw out impurities; for targeted care, apply only to spots or congested zones.

• Use after cleansing and before moisturizers or serums.
• Apply 1–2 times per week, or as tolerated by your skin.
• Rinse thoroughly with lukewarm water and pat dry.
• Follow with a gentle hydrator; avoid excessive exfoliation the same day.

What ingredients make this effective for oily or congested skin?

The formula pairs absorbent kaolin clay with sulfur to support a clearer surface, while glycolic acid helps loosen dead skin cells for smoother texture. Each component is chosen to work together without overly stripping natural moisture.

• Kaolin clay absorbs excess sebum and refines pore appearance.
• Sulfur supports balanced skin in targeted areas.
• Glycolic acid provides gentle chemical exfoliation to reduce buildup.
• Non-drying base to help maintain the skin barrier.

Can I use this as a spot treatment and a full-face mask?

Yes—its dual-purpose design is suitable for both targeted blemish care and an all-over weekly treatment. Apply directly to trouble spots for focused action, or spread thinly across the face for deeper purification.

• Targeted application for active blemishes or congested zones.
• Full-face application for overall texture refinement.
• Compatible with gentle cleansers and follow-up skincare steps.
• Adjust frequency depending on skin sensitivity and oil levels.

Will this disrupt my skin’s moisture or barrier?

The formulation is intended to lift surface impurities while maintaining hydration when used as directed. It combines absorbent and exfoliating ingredients with a base designed to be less stripping than harsher clay treatments.

• Balanced clay base to reduce over-drying.
• Use with a moisturizer after treatment to support barrier health.
• Avoid layering with strong exfoliants on the same day.
• Patch test first if you have highly sensitive skin.

Who is this for: CLEARSTEM SULFUR SPOT & MASK is suited to people with oily, combination, or congested skin looking for a weekly refining mask and a dependable spot treatment. It benefits those wanting a versatile product that can be used both across the face for texture improvement and applied precisely to blemishes, while fitting into a balanced, results-focused skincare routine.
