Description

COSRX AC Collection Acne Patch is a hydrocolloid spot dressing from COSRX’s AC Collection, developed for blemish-prone, sensitive, or wounded-looking areas.

The primary technology is hydrocolloid.

Hydrocolloid absorbs fluid or exudate from a surfaced blemish while maintaining a moist, covered environment. COSRX describes this mechanism as helping absorb discharge while maintaining humidity around the problem area.

The current official material composition is:

Carboxymethylcellulose Sodium, Polyisobutene, Rosin, Polybutene, Mineral Oil, Centella Asiatica Extract, Polyurethane Film.

The addition of Centella Asiatica Extract distinguishes this patch from several simpler COSRX hydrocolloid patches. Centella provides complementary soothing and conditioning support to the covered blemish area.

The patch is designed in an oval shape with tapered edges so it can cover:

• individual larger blemishes,
• two or more neighboring spots,
• jawline acne,
• hairline breakouts,
• and wider blemish-prone areas.

COSRX officially emphasizes the product’s strong adhesion even on curved areas.

This particular patch does not contain Salicylic Acid or Tea Tree Oil in its current formula.

That distinction matters because the separate COSRX Master Patch Intensive does contain 0.02% Salicylic Acid and 0.02% Tea Tree Leaf Oil, whereas AC Collection Acne Patch uses a different hydrocolloid + Centella material system.

Key Materials & Their Benefits

The current official COSRX composition is:

Carboxymethylcellulose Sodium, Polyisobutene, Rosin, Polybutene, Mineral Oil, Centella Asiatica Extract, Polyurethane Film.

Important Rosin Note

The AC Collection Acne Patch contains Rosin as part of its adhesive system.

Most users may tolerate the adhesive without difficulty, but Rosin can cause contact sensitivity in some individuals. Anyone with a known allergy to adhesive resins or Rosin should avoid the product or consult an appropriate healthcare professional before use.

This is also one ingredient that distinguishes AC Collection Acne Patch from some other COSRX patch formulas.

How to Use

COSRX currently instructs users to cleanse the problem area, choose a patch larger than the spot, and apply it to dry skin, generally before toner.

Product Specifications

Important Patch Size Note

COSRX Korea officially specifies the 26-patch pack as:

23 × 15mm × 8 patches

16 × 11mm × 9 patches

13 × 9mm × 9 patches

Total:

26 patches.

These are oval patches, not three sizes of traditional round dots.

The larger shapes make the AC Collection Acne Patch particularly useful for:

• clusters of small blemishes,
• larger surfaced pimples,
• elongated jawline breakouts,
• and body blemishes requiring wider coverage.

AC Collection Acne Patch vs Acne Pimple Master Patch

These products should not be confused.

COSRX AC Collection Acne Patch

• 26 patches
• Oval shape
• 3 sizes
• 23×15mm / 16×11mm / 13×9mm
• Contains Centella Asiatica Extract
• Strong adhesion around curved areas
• Useful for adjacent blemishes and larger affected areas

COSRX Acne Pimple Master Patch

• 24 patches
• Round shape
• 7mm × 10
• 10mm × 5
• 12mm × 9
• Simpler hydrocolloid patch system.

If the customer needs larger or grouped blemish coverage, the AC Collection version offers a practical advantage.

AC Collection Acne Patch vs Master Patch Intensive

The formulas are also different.

AC Collection Acne Patch contains:

• Hydrocolloid materials
• Centella Asiatica Extract
• Rosin
• Mineral Oil

It does not list Salicylic Acid or Tea Tree Oil.

COSRX Master Patch Intensive contains:

• Hydrocolloid
• 0.02% Salicylic Acid
• 0.02% Tea Tree Leaf Oil.

Do not copy the Salicylic Acid or Tea Tree claims from Master Patch Intensive onto this AC Collection Acne Patch.

What Does Hydrocolloid Do?

Hydrocolloid primarily helps by:

• absorbing exudate,
• maintaining moisture,
• covering the blemish,
• reducing contamination from repeated touching,
• and discouraging squeezing or picking.

COSRX specifically describes its hydrocolloid as absorbing discharge while maintaining humidity.

When there is fluid available to absorb, the patch may gradually become more opaque.

That does not mean the patch is releasing pus or chemically “drawing out toxins.” It simply reflects absorbed moisture and exudate within the hydrocolloid.

Which Pimples Work Best?

The patch generally works best on:

• surfaced whiteheads,
• fluid-containing blemishes,
• naturally opened spots,
• blemishes that need physical protection,
• and neighboring surfaced breakouts.

It is generally less effective at extracting material from:

• deep cystic acne,
• closed under-the-skin bumps,
• hard nodules,
• or lesions with no surface fluid.

A deep blemish can still be physically protected by the patch, but the hydrocolloid may have little fluid to absorb.

Important Rosin Allergy Note

Rosin appears in the official material list.

Rosin is commonly used to improve adhesion, but some people can develop allergic contact dermatitis to Rosin-containing adhesive materials.

Stop using the patch if you develop:

• persistent itching,
• unusual swelling,
• blistering,
• spreading redness,
• or irritation matching the shape of the adhesive patch.

This type of reaction is different from the normal appearance of a hydrocolloid patch becoming white after absorbing fluid.

COSRX targets the patch toward sensitive and wounded-looking problem areas. However, the adhesive contains Rosin, which can trigger contact allergy in susceptible individuals, so discontinue use if significant itching, swelling or persistent irritation develops.
