Description

COSRX Master Patch Intensive is an active-infused hydrocolloid blemish patch.

Its current official formula contains:

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

COSRX describes the hydrocolloid component as helping protect the affected area and absorb exudate. The addition of Salicylic Acid and Tea Tree Leaf Oil makes this more treatment-focused than COSRX’s simpler plain hydrocolloid patch options.

The complete current ingredient/material list is:

Cellulose Gum, Hydrogenated Poly(C6-20 Olefin), Polyisobutene, Styrene/Isoprene Copolymer, Salicylic Acid, Melaleuca Alternifolia (Tea Tree) Leaf Oil.

The patch itself has an oval shape with thin tapered edges, helping it conform better to curved areas of the face and remain less visible than a thick flat-edged dressing.

COSRX currently markets the product around:

• protecting the blemish,
• flattening its visible appearance,
• absorbing fluid,
• active spot care,
• discreet coverage,
• and all-day adhesion.

Because this is still primarily a hydrocolloid patch, it performs best when a blemish has reached or approached the skin surface and contains moisture or exudate that can be absorbed.

Deep, completely closed cystic bumps usually provide less fluid for hydrocolloid absorption.

Key Benefits of COSRX Master Patch Intensive

• Absorbs Blemish Exudate
  Hydrocolloid helps collect moisture and fluid from surfaced blemishes.
• Contains 0.02% Salicylic Acid
  Provides a small amount of BHA-based exfoliating support within the patch.
• Contains 0.02% Tea Tree Leaf Oil
  Adds complementary blemish-focused and soothing botanical care.
• Helps Protect Blemishes From Touching
  Physical coverage helps discourage squeezing, scratching and repeated contact.
• Designed to Help Flatten Surfaced Pimples
  COSRX specifically markets Master Patch Intensive for protecting and flattening visible blemishes.
• Discreet Tapered-Edge Design
  Thin oval edges help the patch blend more naturally into surrounding skin.
• Strong All-Day Adhesion
  COSRX highlights all-day adhesion as one of the product’s primary features.
• Two Sizes for Different Blemishes
  Includes both 13×9mm and 16×11mm oval patches, giving more coverage flexibility.

Key Ingredients & Materials and Their Benefits

COSRX’s current official formula lists only these six materials/ingredients.

Important Concentration Note

The active levels are:

Salicylic Acid – 0.02%

Tea Tree Leaf Oil – 0.02%

These are low concentrations incorporated into the patch.

Do not describe Master Patch Intensive as:

“2% Salicylic Acid patch”

or

“high-strength Tea Tree treatment.”

The correct wording is:

“Hydrocolloid patch infused with 0.02% Salicylic Acid and 0.02% Tea Tree Leaf Oil.”

How to Use

COSRX’s current directions say to cleanse and dry the problem spot first, then place the patch with the sticky side against the skin.

Current retailer directions additionally recommend applying the patch before other skincare steps and replacing it daily or when it turns white.

Product Specifications

Important Size Breakdown

COSRX officially lists the 36-count pack in:

13 × 9mm

and

16 × 11mm sizes.

Current retail specifications further break the pack down as:

13 × 9mm × 18 patches

16 × 11mm × 18 patches

Total:

36 patches.

Both are oval rather than traditional circular dots.

Important Active Ingredient Note

COSRX clearly specifies:

0.02% Salicylic Acid

and

0.02% Tea Tree Leaf Oil.

That makes Master Patch Intensive different from a plain hydrocolloid patch.

However, these are still relatively small amounts, so the patch should not be described as equivalent to:

• a 2% Salicylic Acid leave-on serum,
• a strong chemical peel,
• prescription acne medication,
• or a concentrated Tea Tree spot treatment.

Its primary physical mechanism remains:

hydrocolloid absorption + physical protection.

The acids/oils provide complementary active spot care.

Master Patch Intensive vs Master Patch Basic

COSRX currently sells both:

Master Patch Basic

and

Master Patch Intensive.

Master Patch Intensive

• 36 patches
• Two oval sizes
• 13×9mm and 16×11mm
• Hydrocolloid
• 0.02% Salicylic Acid
• 0.02% Tea Tree Leaf Oil
• Tapered edges
• More active blemish-care positioning

Master Patch Basic

• Basic hydrocolloid patch concept
• No Salicylic Acid or Tea Tree Oil highlighted in the same way
• Intended for straightforward daily pimple coverage

Customers wanting active-infused hydrocolloid care may prefer Master Patch Intensive.

Master Patch Intensive vs COSRX AC Collection Acne Patch

These two are also different.

Master Patch Intensive

Contains:

• hydrocolloid,
• 0.02% Salicylic Acid,
• 0.02% Tea Tree Leaf Oil.

Sizes:

• 13×9mm
• 16×11mm

Total:

• 36 patches.

AC Collection Acne Patch

Contains:

• hydrocolloid materials,
• Centella Asiatica Extract,
• no Salicylic Acid,
• no Tea Tree Oil.

The AC Collection version also includes larger oval patch options.

Therefore:

Want Salicylic Acid + Tea Tree Oil → Master Patch Intensive

Want Centella + larger multi-size coverage → AC Collection Acne Patch

Master Patch Intensive vs Clear Fit Master Patch

Master Patch Intensive

• Active-infused
• Salicylic Acid
• Tea Tree Oil
• Two oval sizes
• Stronger blemish-treatment positioning

Clear Fit Master Patch

• 18 patches
• Single 10mm size
• Ultra-thin
• Designed especially for discreet daytime and under-makeup wear
• No Salicylic Acid or Tea Tree Oil in its standard material list

For more discreet cosmetic daytime coverage, Clear Fit may be preferable.

For active-infused spot care, Master Patch Intensive is the stronger option.

What Does the Hydrocolloid Do?

The hydrocolloid portion helps:

• absorb exudate,
• cover the blemish,
• protect against touching,
• maintain a controlled covered environment,
• and visibly flatten fluid-producing spots as moisture is absorbed.

COSRX specifically describes hydrocolloid as providing wound protection and exudate absorption.

As the patch absorbs moisture, it may gradually turn:

white / opaque / swollen.

This is normal and usually indicates that moisture has entered the hydrocolloid layer.

It does not mean the patch is literally extracting “toxins.”

Which Pimples Work Best?

Most suitable for:

• whiteheads,
• surfaced pimples,
• fluid-producing blemishes,
• naturally opened spots,
• inflamed spots that need physical protection.

Less suitable for extracting fluid from:

• deep cystic acne,
• blind pimples,
• hard closed bumps,
• nodules with no surface opening.

A deep spot can still be protected from touching, but there may be very little exudate for the patch to absorb.

Salicylic Acid & Aspirin Allergy Warning

Current retailer safety information warns that individuals with an aspirin allergy may react poorly to the Salicylic Acid in this patch.

Avoid use if you have a known salicylate sensitivity unless a qualified healthcare professional has advised otherwise.

Stop using the product if significant:

• rash,
• swelling,
• burning,
• persistent redness,
• or unusual itching develops.

Tea Tree Oil & Sensitive Skin

The patch contains 0.02% Melaleuca Alternifolia (Tea Tree) Leaf Oil.

Although the concentration is low, Tea Tree Oil is still an aromatic essential oil.

Therefore, Infinity Skincare Solutions should not describe this product as:

“essential-oil-free.”

For very sensitive skin, adhesive-sensitive skin, or known Tea Tree allergy, patch testing and careful monitoring are appropriate.

FAQs

4. Does COSRX Master Patch Intensive contain Tea Tree Oil?

5. Is Master Patch Intensive the same as AC Collection Acne Patch?

No. Master Patch Intensive contains Salicylic Acid and Tea Tree Oil. AC Collection Acne Patch instead uses Centella Asiatica Extract within its hydrocolloid system and does not contain those two actives.

6. Should I apply skincare before the patch?

No. Apply the patch to clean, completely dry skin before other skincare products for the best adhesion. Current retailer directions specifically recommend this order.

7. When should I change the patch?

Replace it when it becomes white/opaque from absorbed fluid, starts losing adhesion or according to daily-use needs.

8. Does Master Patch Intensive work on cystic acne?

It can physically cover a deep blemish, but hydrocolloid absorbs best when a pimple has surface fluid. Deep blind or cystic bumps usually provide less fluid for the patch to absorb.

9. Can someone with an aspirin allergy use it?

Current retailer safety information warns that people allergic to aspirin may react poorly to Salicylic Acid. Users with known aspirin or salicylate sensitivity should avoid the patch unless appropriately advised by a healthcare professional.
