This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate suitability for normal skin as liquid paraffin provides emollient action, but the presence of petroleum resin is irrelevant for your redness and irritation concerns.
- Cellulose gum aids in absorbing exudate and protecting blemishes, offering excellent treatment for acne-prone skin.
- The product is safe for your sensitive skin due to the absence of prohibited or harsh ingredients.

## What the research says

- Biocellulose and carboxymethyl cellulose wound dressings significantly reduced healing times and wound areas compared to normal saline dressings in epidermolysis bullosa skin wounds. ([Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/))
- Polymeric bioadhesive microparticles composed of sodium carboxymethyl cellulose and Soluplus and loaded with 18beta-glycyrrhetinic acid form an in situ hydrogel upon contact with wound exudate, enabling controlled drug release that stimulates keratinocyte growth. ([International Journal of Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33862131/))
- Daily application of hydrocolloid dressing completely prevented nasogastric tube-related pressure injuries, whereas skin care interventions showed no significant preventive effect compared to the control group in intensive care unit patients. ([Journal of Tissue Viability, 2024](https://pubmed.ncbi.nlm.nih.gov/39289093/))
- Hydration of scars for 2 months resulted in significantly reduced itching, somewhat reduced pain, and increased pliability by 10% for both hydrocolloid dressing and moisturizer treatments in patients with keloids or hypertrophic scars, with no change in physical parameters. ([Dermatologic Surgery, 1996](https://pubmed.ncbi.nlm.nih.gov/8874525/))

([Skin Health and Disease, 2023](https://pubmed.ncbi.nlm.nih.gov/37538322/))
- Cross-linked carboxymethyl cellulose hydrogel provided excellent correction of facial defects, high tolerance, and absence of side effects or migration issues in 84 healthy volunteers. ([Clinical Interventions in Aging, 2010](https://pubmed.ncbi.nlm.nih.gov/21228896/))
- Biodegradable wound dressings functionalized with silver nanoparticles showed >99% pathogen growth inhibition, bactericidal effects, free radical scavenging, reduced inflammatory response in macrophages, and accelerated wound healing in animals. ([International Journal of Biological Macromolecules, 2022](https://pubmed.ncbi.nlm.nih.gov/35780920/))
- 3D-printed carboxymethyl cellulose/ε-polylysine hydrogels exhibited 95% antibacterial inhibition against E. coli and S. aureus, removed excessive reactive oxygen species, and promoted wound healing with increased VEGF and CD31 expression compared to Tegaderm film. ([International Journal of Biological Macromolecules, 2021](https://pubmed.ncbi.nlm.nih.gov/34298048/))
- Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients. ([CMAJ, 2010](https://pubmed.ncbi.nlm.nih.gov/20837684/))

([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))
- Treatment with 2% supramolecular salicylic acid hydrogel resulted in a regression and markedly improvement rate of 51.01% compared to 43.10% for Adapaline gel in patients with mild to moderate facial acne vulgaris, showing no significant difference in efficacy. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38590107/))

## What reviewers say

Based on a very large amount of data, this hydrocolloid patch is highly praised for its ability to extract impurities from whiteheads and prevent scarring by discouraging skin picking. It is very effective for surface-level pimples with visible heads, though it is generally reported as ineffective for deep, cystic, or hormonal acne that has not yet surfaced.

- Liked: Prevents skin picking (often mentioned)
- Liked: Speeds up healing (often mentioned)
- Disliked: Ineffective on cystic acne (often mentioned)

## How to apply

- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .

## Questions and answers

### How well does COSRX Acne Pimple Master Patch work for sensitive skin?

This patch works for sensitive skin, though other products fit it better because they target redness and irritation more effectively. Treatments that fit sensitive skin better need soothing components like niacinamide and snail secretion filtrate to calm irritation while caring for blemishes.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/), [International Journal of Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33862131/)

### Which ingredients make this patch a good fit for sensitive skin?

This patch works for sensitive skin because it is free from harsh ingredients and contains cellulose gum, which helps absorb blemish fluid while protecting the area. A treatment for this skin needs soothing ingredients like niacinamide or snail secretion filtrate to help calm redness and irritation.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/), [International Journal of Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33862131/)

### What does Hydrocolloid Dressing do for sensitive skin?

Hydrocolloid Dressing may cause irritation on sensitive skin due to its adhesive properties, as studies show it can lead to higher skin redness and barrier disruption compared to softer alternatives. When using this type of product on easily irritated skin, it needs a gentle removal method and a strong focus on skin protection.
Sources: [ACS Applied Bio Materials, 2024](https://pubmed.ncbi.nlm.nih.gov/38150300/), [Journal of Wound Care, 2007](https://pubmed.ncbi.nlm.nih.gov/17385583/)

### What does Cellulose Gum do for sensitive skin?

Cellulose gum is generally safe and well tolerated for sensitive skin, helping to maintain product texture without causing irritation. It forms a gentle layer on the skin that supports moisture retention.

### Where does this patch go in a skincare routine for sensitive skin?

This patch goes in the evening routine as a treatment step, used once a week to start. Sensitive skin works best with treatments that protect blemishes while avoiding harsh ingredients that cause redness.

### Can I use this patch with retinol, and in what order?

You can use this patch with retinol by applying the patch to clean skin in your evening routine, but avoid placing it directly over irritated spots when using strong active ingredients. A product for this skin type needs soothing ingredients like centella asiatica or green tea and gentle barrier-repairing elements to help calm redness and protect sensitive areas.

### How often should I use this patch?

You can use this treatment in your evening routine once a week to start. Sensitive skin needs treatments that absorb fluid and protect blemishes while using soothing ingredients to keep skin calm.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

### Can this patch clog pores, cause breakouts or purging for sensitive skin?

This patch is unlikely to clog pores or cause breakouts on sensitive skin due to the absence of harsh ingredients, though it may not help with deep cystic acne. Sensitive skin types typically need breathable materials and soothing ingredients that protect blemishes without causing irritation.
