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

Works for dry sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate suitability for dry skin as liquid paraffin provides emollient action, but it lacks sufficient humectant ingredients to fully address your dryness.
- The presence of cellulose gum aids in absorbing exudate and protecting blemishes, offering excellent treatment for acne-prone skin.
- The product is safe for your dry and 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.

- 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/))
- 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/))

- 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. ([International Journal of Pharmaceutics, 2019](https://pubmed.ncbi.nlm.nih.gov/31525444/))

## Why other serums fit dry sensitive skin better

- A formulation containing glycerol (5%) and xylitol (5%) applied twice daily for 14 days increased skin hydration, filaggrin protein quantity, interdigitation index, and biomechanical properties, and decreased transepidermal water loss compared to untreated and vehicle-treated skin in twelve volunteers with dry skin. ([Acta Dermato-venereologica, 2017](https://pubmed.ncbi.nlm.nih.gov/27349297/))
- Glycerol accelerates barrier repair and improves stratum corneum hydration compared to untreated and base-treated sites. ([Acta Dermato-venereologica, 1999](https://pubmed.ncbi.nlm.nih.gov/10598752/))
- In 50 participants with sensitive skin, a Ceramide NP C15-containing emollient improved skin barrier function with a significant reduction in transepidermal water loss and induced modest changes in skin microbiota compared to the vehicle.

## 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: Extracts gunk effectively (mostly mentioned)
- Liked: Prevents skin picking (often mentioned)
- Liked: Speeds up healing (often mentioned)
- Disliked: Ineffective on cystic acne (often mentioned)
- Liked: Stays on well (sometimes noted)
- Disliked: Not truly invisible (sometimes noted)
- Disliked: Adhesion issues (rarely noted)

## How to apply

- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

## Questions and answers

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

This patch is a fair match for dry sensitive skin because liquid paraffin softens the area, but it lacks enough hydrating ingredients to fully handle your dryness. A product for this skin type needs rich moisturizing ingredients and skin barrier support to provide deep hydration and prevent irritation.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

Liquid paraffin helps soften dry skin through its smoothing action, while cellulose gum protects blemishes and absorbs fluid. Because dry sensitive skin needs more, a product of this type needs extra hydrating ingredients that add moisture and support the skin barrier.
Sources: [Journal of Wound Care, 2019](https://pubmed.ncbi.nlm.nih.gov/31600103/)

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

Hydrocolloid Dressing may irritate dry sensitive skin and disrupt the skin barrier, as repetitive removal tends to increase moisture loss in vulnerable areas. A product of this type for dry sensitive skin needs gentle soft silicone adhesives or added ceramides to protect the skin and keep it calm and smooth.
Sources: [Journal of Wound Care, 2006](https://pubmed.ncbi.nlm.nih.gov/16711170/), [Journal of Wound Care, 2007](https://pubmed.ncbi.nlm.nih.gov/17385583/)

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

Cellulose gum helps keep moisture locked in and gives products a smooth, easy-to-spread feel that is unlikely to upset sensitive areas. For dry sensitive skin, a product of this type needs gentle soothing ingredients and rich moisture-locking components to keep the skin barrier calm and comfortable.

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

This treatment goes in the evening routine after cleansing and toning, followed by a moisturizer. Dry sensitive skin also needs rich hydrating ingredients and soothing moisture to fully address dryness while treating blemishes.

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

You can use this patch in your routine with retinol by placing it on blemishes after your soothing toner and before your moisturizer. It is unlikely to irritate your dry and sensitive skin since it avoids harsh ingredients, but because it lacks heavy hydrating ingredients, your routine needs nourishing moisturizers to fully address your dryness.

### How often should I use this patch?

Use this patch in the evening as a treatment step, and use it once a week at first since it is a new addition to your routine. This product is safe for your dry and sensitive skin, but a product of this type needs extra hydrating ingredients that draw moisture into the skin to fully address your dryness.

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

This patch is unlikely to clog pores or cause breakouts on dry sensitive skin due to its safe ingredients, though a product for this skin type needs extra hydrating ingredients to fully address dryness.
