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

Brand: [ONE/SIZE](https://lovi.care/skincare/ca/brands/one-size)

This fit is calculated for the concerns frequently associated with oily skin: shine, enlarged pores, blackheads, and blemishes. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily skin; other products fit it better.

## Why this fit

- Offers moderate mattifying for your oily skin due to the presence of silica and dimethicone, which absorb excess oil and provide emollient action, respectively. Glycerin also offers hydration without exacerbating oiliness.
- While the product provides general skincare benefits like hydration and cleansing, it lacks specialized ingredients to directly target and control oily shine.
- The formula is safe for your oily skin, as it contains no harsh ingredients and includes soothing components like glycerin.

## Key ingredients

Dimethicone, Cyclopentasiloxane

## What the research says

- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups. ([Military Medicine, 2024](https://pubmed.ncbi.nlm.nih.gov/38771104/))
- A dimethicone skin protectant lotion significantly decreased visual scoring and transepidermal water loss compared to vehicle control and SLS-only treated sites in 12 healthy humans exposed to sodium lauryl sulfate. ([Skin Research and Technology, 2000](https://pubmed.ncbi.nlm.nih.gov/11428946/))
- Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms. ([Clinical and Experimental Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17137484/))

## Why other products fit oily skin better

- Topical benzoyl peroxide 5% gel treatment improved acne severity, sebum, stratum corneum hydration, and transepidermal water loss, while significantly reducing microbial diversity and the prevalence of Cutibacterium in 33 patients with acne vulgaris. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/34962033/))

## Questions and answers

### How well does ONE/SIZE Oil Sucker Primer work for oily skin?

ONE/SIZE Oil Sucker Primer works moderately well for your oily skin by providing basic hydration and absorbing excess shine, though other products fit this skin better. A makeup primer for oily skin needs specialized ingredients that directly control oil and target shine, such as niacinamide, salicylic acid, or zinc gluconate.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this primer a good fit for oily skin?

Silica, dimethicone, and glycerin make this primer a moderate fit because they absorb excess oil, smooth the skin, and provide light hydration without making it greasy. However, because it lacks specialized oil-controlling ingredients, a product for oily skin of this type needs ingredients like niacinamide, salicylic acid, zinc gluconate, or willow bark extract to truly manage shine and target pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Water do for oily skin?

Water helps keep oily skin hydrated without adding grease or clogging pores. Keeping oily skin properly hydrated may also help balance oil production and reduce unwanted shine.

### What does Dimethicone do for oily skin?

Dimethicone helps protect skin and lock in moisture, though it may have limited performance compared to petrolatum. For oily skin, a product of this type needs a lightweight, oil-free formula that hydrates without clogging pores.
Sources: [Ostomy/wound Management, 2005](https://pubmed.ncbi.nlm.nih.gov/16439809/)

### Where does this primer go in a skincare routine for oily skin?

This makeup primer is applied in the morning after your moisturizer and sunscreen. Because your oily skin needs more specialized ingredients to control shine, a product of this type needs mattifying and oil-absorbing ingredients like silica and dimethicone to better keep excess oil in check.

### Can I use this primer with salicylic acid, and in what order?

You can use this primer with salicylic acid by applying your salicylic acid treatment first, letting it dry, and then smoothing on your primer. Oily skin also needs targeted shine-control ingredients like oil-absorbing powders and sebum-regulating actives to properly manage excess shine.

### How often should I use this primer?

This primer can be used daily as part of your morning makeup routine. It helps keep your oily skin feeling comfortable and balanced throughout the day.

### Can this primer clog pores, cause breakouts or purging for oily skin?

This primer is unlikely to cause breakouts or clog pores on oily skin because it contains no harsh ingredients and includes safe, soothing components like glycerin. However, because it lacks specialized ingredients to directly control oily shine, oily skin needs a product with strong oil-absorbing ingredients to stay completely matte.

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

Yes, it has no fragrance and no drying alcohol.
