The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Singapore.

Brand: [Dr. Dennis Gross](https://lovi.care/skincare/sg/brands/dr-dennis-gross)
Category: [Face masks](https://lovi.care/skincare/sg/best/face-masks)

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.

A poor match for dry skin; the cleansing masks alongside fit it better.

## Why this fit

- Offers moderate exfoliation for your dry or flaky skin due to colloidal sulfur and willow bark extract, which provide mild skin renewal.
- While the mask effectively cleanses pores with colloidal sulfur and zinc oxide, its kaolin and bentonite content can be drying for your dry skin, and it lacks sufficient emollients and humectants to counteract this.

## What the research says

- Azelaic acid was probably less effective than benzoyl peroxide in acne treatment response, while showing little or no difference compared to tretinoin, and adverse events were mild and transient across evaluated topical treatments. ([Journal of Evidence-based Medicine, 2020](https://pubmed.ncbi.nlm.nih.gov/33034949/))
- Topical application of precipitated sulphur 2-8% petrolatum achieved a 95% clinical and ectoparasitological cure rate in 40 ambulatory scabies patients without relevant adverse effects.

- Topical 10% benzoyl peroxide and 2%-5% sulfur cream achieved "good" to "excellent" results with no undesirable side effects in 113 consecutive patients with acne. ([Canadian Medical Association Journal, 1966](https://pubmed.ncbi.nlm.nih.gov/4223133/))
- Topical 0.5% hyaluronic-ZnO nanogel applied twice daily reduced inflammatory-lesion counts by 58% at week four in human subjects compared to baseline without causing erythema. ([Biomedicines, 2025](https://pubmed.ncbi.nlm.nih.gov/41007718/))
- Nels cream achieved a similar reduction in inflammatory and noninflammatory lesion counts compared to 5% benzoyl peroxide in acne vulgaris patients, but caused significantly fewer side-effects such as peeling and dryness. ([Clinical and Experimental Dermatology, 2000](https://pubmed.ncbi.nlm.nih.gov/10671963/))
- Topically applied coated and uncoated zinc oxide nanoparticles under flexing and massage are retained in the stratum corneum with no significant penetration into the viable epidermis and no cellular toxicity in human skin. ([Nanomedicine, 2016](https://pubmed.ncbi.nlm.nih.gov/27102240/))
- Combining 755 nm alexandrite laser with topical licorice gel significantly reduces terminal hair counts compared to alexandrite laser with placebo in women with idiopathic hirsutism. ([Evidence-based Complementary and Alternative Medicine, 2015](https://pubmed.ncbi.nlm.nih.gov/26273313/))
- Licochalcone A activated Nrf2 signaling, elevated cytoprotective enzymes, increased the reduced-to-oxidized glutathione ratio, and decreased reactive oxygen species in human fibroblasts and neutrophils, while a LicA-rich licorice extract lowered UVA-induced oxidative processes in vivo. ([Experimental Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25381913/))
- Bioactive glycyrrhizic acid and oxymatrine ionic liquid self-assembled nanomicelles significantly promoted the transdermal permeation, subcutaneous retention, and anti-photoaging efficacy of palmitoyl pentapeptide-4 in cellular and animal models compared to unformulated peptide. ([Advanced Science, 2025](https://pubmed.ncbi.nlm.nih.gov/39783908/))

([International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/))
- Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging. ([The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/))
- Silicone particles encapsulating retinol increased its half-life by 9-fold and yielded 12-23% lower skin irritation in human subjects compared to Microsponge particles while maintaining biological activity. ([Journal of Controlled Release, 2018](https://pubmed.ncbi.nlm.nih.gov/29604311/))

## What reviewers say

Based on limited data, users frequently report that this mask effectively calms inflammation, reduces redness, and shrinks active breakouts, often with overnight improvements, making it particularly beneficial for acne-prone and oily skin. A notable drawback is the strong sulfur scent, and some users express frustration with the pump packaging.

## How to apply

- Use this cleansing mask PM as part of your weekly routine, starting 1x/week and increasing slowly if needed. Always follow with a rich moisturizer to prevent dryness.
- Apply the cleansing mask after using your cleanser and enzyme powder, but before your hydrating toner and moisturizer. This ensures the mask works effectively on your dry skin.
- Smooth an even layer of the cleansing mask over your face while avoiding any rubbing. Let it sit for the recommended time before gently rinsing it off.
- Apply the cleansing mask to clean, dry skin for the best comfort. Since your skin is dry, this method helps prevent any potential irritation.
- Avoid the sensitive eye area during application. Do a patch test before your first use to ensure your skin tolerates the product well.

## Questions and answers

### Why does Lovi advise caution with the Clarifying Colloidal Sulfur Mask for dry skin?

Lovi advises caution because the mask contains drying clays like kaolin and bentonite without enough rich, hydrating ingredients to balance them out. A product of this type for dry skin needs plenty of soothing moisturizers and gentle hydrators to keep skin soft and comfortable.

### Which ingredients make this mask a poor fit for dry skin?

This mask is a poor fit for dry skin because its kaolin and bentonite can dry out dry skin, and it lacks enough rich moisturizing and hydrating ingredients to balance them out. A product of this type needs plenty of soothing hydration and moisture to keep dry skin soft and comfortable.
Sources: [Nanomaterials, 2022](https://pubmed.ncbi.nlm.nih.gov/35889587/)

### What does Zinc Oxide do for dry skin?

Zinc oxide is unlikely to help dry skin on its own, because repeated use of this ingredient may increase water loss and lead to a scaly appearance. A product for dry skin needs extra ingredients that lock in moisture and soothe the skin.
Sources: [Skin Research and Technology, 2005](https://pubmed.ncbi.nlm.nih.gov/15807813/)

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

This mask is a poor match for dry skin because its clay ingredients can be overly drying, and it lacks enough moisturizing ingredients to counteract them. A mask for dry skin needs plenty of rich hydrators and softening oils to keep the skin comfortable and smooth.

### Can I use this mask with benzoyl peroxide, and in what order?

It is best to avoid using this mask with benzoyl peroxide, because the combination of sulfur, clays, and acne treatments may easily over-dry and irritate your dry skin. A product of this type needs rich moisturizers and gentle hydrators to keep your skin soft and comfortable.

### How often should I use this mask?

This mask is a poor match for your dry skin because its clays and sulfur can dry you out further without enough moisture-locking ingredients to balance them. When using a product of this type on dry skin, you need soothing plant extracts and heavy moisture-locking ingredients to keep your face soft and comfortable.

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

This mask helps clear pores for dry skin with colloidal sulfur and zinc oxide, but its clay ingredients may dry out your skin further. A product for this skin needs rich hydrators and soothing oils to keep it soft and comfortable.

### Is this mask fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (farnesol). Cetearyl alcohol is a fatty alcohol, which soften the skin.
