This fit is calculated for the concerns frequently associated with dry skin: flakiness, tightness, dehydration, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for dry skin; other serums fit it better.

## Why this fit

- Offers moderate suitability for dry skin as cellulose gum helps absorb exudate and protect blemishes, though it lacks essential humectants and emollients to directly address dryness.
- The formula provides general skincare benefits and is safe for your dry skin due to the absence of harsh ingredients, but it does not offer specialized hydration or smoothing for flaky skin.
- The safety profile is excellent, with no risks of irritation for your dry 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/))
- 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/))
- 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/))

## Questions and answers

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

COSRX Acne Pimple Master Patch works moderately well for dry skin by protecting blemishes and absorbing fluid, though it does not provide specialized hydration for dry areas. It is unlikely to cause irritation due to its gentle formula, but dry skin needs treatments containing hydrating and skin-repairing ingredients like propolis, niacinamide, ceramides, vitamin C, or peptides.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

Cellulose gum is the key ingredient that helps protect blemishes and absorb fluid on your dry skin. Because this patch lacks specialized hydrating ingredients, a treatment for dry skin needs nourishing components like ceramides, vitamin C, peptides, or propolis and niacinamide to keep skin soft and smooth.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

Hydrocolloid Dressing may increase skin moisture when applied to dry skin, though repetitive removal can sometimes disrupt the skin barrier. A product of this type needs gentle adhesive edges and hydrating ingredients like ceramides to protect dry skin.
Sources: [Journal of Wound Care, 2006](https://pubmed.ncbi.nlm.nih.gov/16711170/)

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

Cellulose Gum helps keep dry skin soft and smooth by holding moisture in place and supporting a comfortable feel. This ingredient has a very safe profile and is unlikely to cause irritation when used in your daily skincare routine.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

This patch goes in the evening routine after cleansing and before moisturizing, though it only offers moderate suitability for dry skin. Because it lacks essential hydrating and softening ingredients to directly address dry and flaky skin, a dry skin routine needs additional moisturizing ingredients and soothing hydrators.

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

You can use this patch while using retinol, applying it directly on blemishes during your evening routine after your moisturizer has absorbed. The patch is unlikely to irritate dry skin, but a product for this skin needs added humectants and emollients to prevent dryness.

### How often should I use this patch?

You can use this treatment in your evening routine. A product of this type needs moisture-binding ingredients and nourishing oils to keep dry skin soft and smooth.

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

This patch is unlikely to clog pores or cause breakouts on dry skin because it is free of harsh ingredients and has a very safe formula. It helps protect blemishes without causing irritation, though a product for dry skin also needs extra moisture and softening ingredients to keep flaky areas smooth.
