COSRX Master Patch Intensive hydrocolloid pimple patches, 36 oval patches — tea tree & salicylic acid for fast blemish repair

COSRX Master Patch Intensive is a pack of 36 oval hydrocolloid pimple patches formulated with tea tree oil and salicylic acid to protect blemishes, absorb impurities, and support faster-looking skin repair.

These oval-shaped hydrocolloid stickers are designed to sit flush against curved areas like the jawline and hairline while remaining discreet thanks to a clear-matte finish and tapered edges. Each pack includes two sizes so you can choose the patch that best fits the breakout. The patch absorbs exudate, shields the area from bacteria and friction, and contains skin-friendly actives—tea tree oil for its clarifying scent and salicylic acid for mild exfoliating support. Use them during the day or overnight; replace every 6 hours for optimal absorbency.

How do these patches work on active pimples?

The hydrocolloid material creates a moist, protective barrier that absorbs fluid from the blemish and reduces exposure to external irritants. While the patch helps contain discharge and reduce picking, the included salicylic acid helps gently support pore turnover and the tea tree oil provides a calming botanical note.

• Hydrocolloid core draws out fluid and seals the site
• Salicylic acid supports clearer pores and exfoliation
• Tea tree oil delivers a clarifying botanical component
• Oval shape fits curved facial areas like jawline and temples

Will the patches stay on during sleep or exercise?

Yes — the matte, tapered edges are engineered to adhere through mild movement and overnight wear. For best results, apply to clean, dry skin and press down firmly around the entire edge; replace patches every 6 hours or when they become saturated.

• Works through the night when applied correctly
• Stays on during light activity and daily routines
• Change every 6 hours for continued absorption
• Avoid heavy sweating or oil-rich products before application

What sizes are included and how do I choose one?

The set contains medium and small oval patches to match different lesion sizes and locations. Use the smaller patches for tiny whiteheads or pinpoint spots and the medium ovals for larger pustules or locations along curved contours.

• Small: 0.51" x 0.35" — ideal for isolated pinpoint blemishes
• Medium: 0.62" x 0.43" — better for larger or curved areas
• Mix-and-match for jawline, temples, chin, or forehead use
• Choose the size that fully covers the lesion without overlapping healthy skin

How do I apply and remove these blemish patches?

Cleanse and dry the area thoroughly before application to ensure maximum adhesion. Press the patch down for several seconds; when the patch turns white it indicates absorbed fluid — gently peel off and discard, then reapply a new patch if needed.

• Apply to clean, dry skin; avoid oils and moisturizers at the site
• Press edges firmly for a secure seal
• When patch turns opaque, remove and replace if required
• Safe for day or overnight use; do not stretch the patch during removal

Who is this for: COSRX Master Patch Intensive is suitable for anyone seeking a discreet, easy-to-use spot treatment for occasional breakouts, especially those who want non-invasive protection on curved facial areas. It’s useful for people who pick at blemishes and need a physical barrier, those who prefer targeted, single-spot care instead of full-face treatments, and users looking for a product compatible with makeup-friendly wear. Avoid use on open wounds or severely irritated skin; discontinue if irritation occurs. As with any topical product, patch performance varies by skin type and condition.
