This fit is calculated for the concerns frequently associated with combination skin: an oily T-zone, enlarged pores, and dry cheeks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for combination skin; other serums fit it better.

## Why this fit

- Offers moderate suitability for your combination skin, as liquid paraffin provides emollient action, but it lacks sufficient humectants for optimal hydration.
- The cellulose gum effectively absorbs exudate and protects blemishes, offering excellent treatment for acne-prone skin.
- The safety profile is excellent, with no risks of irritation for your combination 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/))
- 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/))
- Adjunctive hydrocolloid dressing with 0.1% mometasone furoate cream significantly increased treatment efficacy and cost-effectiveness compared to topical steroid alone in patients with moderate to severe lichen simplex chronicus. ([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/))
- 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/))
- 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/))
- 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/))
- A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase. ([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))

([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38590107/))
- A cream combining propolis, tea tree oil, and Aloe vera reduced erythema scars, acne severity index, and total lesion count better than erythromycin cream in sixty patients with mild to moderate acne vulgaris compared to placebo. ([Clinical Pharmacology, 2018](https://pubmed.ncbi.nlm.nih.gov/30588129/))
- Tea tree oil nanoemulsion containing adapalene gel demonstrated significantly greater reductions in total, inflammatory, and non-inflammatory acne lesions as well as acne severity index compared to adapalene marketed gel in 100 patients with acne vulgaris over 12 weeks. ([Archives of Dermatological Research, 2022](https://pubmed.ncbi.nlm.nih.gov/34251536/))
- Topical 5% tea tree oil gel significantly improved total acne lesions and acne severity index compared to placebo in 60 patients with mild to moderate acne vulgaris, showing 3.55 times and 5.75 times greater efficacy respectively. ([Indian Journal of Dermatology, Venereology and Leprology, 2007](https://pubmed.ncbi.nlm.nih.gov/17314442/))
- Repeated application of concentrated water-in-oil emulsions over four weeks caused no skin irritation, positively affected skin properties, and delivered almost 50% of the applied fluorescein sodium, with isopropyl myristate showing superior penetration performance compared to liquid paraffin in healthy volunteers.

## Questions and answers

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

This patch is an average fit for combination skin because while it protects blemishes well, it lacks the extra moisture this skin type needs. A product for this skin needs ingredients like niacinamide, propolis, and zinc PCA to provide balanced hydration and control oil without causing dryness or excess shine.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

The cellulose gum makes this patch a good fit for combination skin because it effectively absorbs fluid and protects blemishes. A product of this type needs ingredients like niacinamide and propolis to balance oiliness and provide optimal hydration without causing dryness.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

Hydrocolloid dressings are unlikely to suit combination skin well, as they are designed to manage moisture in specific wound care rather than everyday facial needs. A product for combination skin typically needs balancing ingredients that hydrate dry areas while keeping oily zones clear.
Sources: [Journal of Gerontological Nursing, 1993](https://pubmed.ncbi.nlm.nih.gov/8509607/)

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

Cellulose Gum helps keep skincare products smooth and well-mixed so they spread easily on your skin. A product of this type for combination skin needs soothing ingredients and lightweight moisture that hydrate dry patches without making oily areas greasy.

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

This patch goes in the evening routine after cleansing and toning. For a better fit on combination skin, this type of product also needs hydrating ingredients to keep the skin balanced.

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

You can use this patch in your evening routine after applying your retinol, placing it directly onto clean, dry blemishes. This product is unlikely to cause irritation on combination skin, but achieving a great fit for this skin type requires adding extra water-attracting hydrators so it stays balanced.

### How often should I use this patch?

You can use this patch in your evening routine when treating blemishes. This product of this type needs more water-attracting ingredients to keep your combination skin hydrated.

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

This patch is unlikely to clog pores or cause breakouts for combination skin because it has a very safe formula without harsh ingredients. However, a product for this skin also needs ingredients that add plenty of moisture to keep dry areas balanced.
