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

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

This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

A weak match for sensitive skin; the products alongside fit it better.

## Why this fit

- Offers moderate mattifying for your normal skin due to silica absorbing excess oil, but it does not directly address your primary concerns of redness and irritation.
- Dimethicone provides emollient action, offering general skincare benefits that are supportive rather than targeted for your specific needs.
- The product is safe for your sensitive skin as it lacks prohibited or harsh ingredients, ensuring no risks of irritation.

## Key ingredients

Dimethicone, Cyclopentasiloxane

## What the research says

- Petrolatum-based skin protectants demonstrated protection against irritants and maceration while providing skin hydration, whereas dimethicone and zinc oxide products showed varying or limited performance across parameters among 18 healthy volunteers compared to positive and negative controls. ([Ostomy/wound Management, 2005](https://pubmed.ncbi.nlm.nih.gov/16439809/))
- Cyclomethicone and specific chain length cyclic siloxanes (n = 4-7) are safe in present practices of use and concentration, showing minimal percutaneous absorption, no skin irritation or sensitization, and unlikely significant systemic exposure from cosmetics. ([International Journal of Toxicology, 2011](https://pubmed.ncbi.nlm.nih.gov/22247236/))
- 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/))
- 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/))
- Externally applied substances such as ceramides, hyaluronic acid, licorice extracts, dimethicone, petrolatum, and paraffin wax treat skin disease resulting from damage to the skin barrier. ([Clinics in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22507050/))

## Why other products fit sensitive skin better

- Topical application of TAT-SOD significantly suppresses UVB-induced erythema formation, blood flow rise, and apoptotic sunburn cell formation in human volunteers compared to a vehicle control. ([European Journal of Pharmaceutics and Biopharmaceutics, 2016](https://pubmed.ncbi.nlm.nih.gov/27460952/))
- Cosmetic formulations containing 5% Centella asiatica extract showed the best efficacy in improving skin moisture and decreasing transepidermal water loss, while also exhibiting antiinflammatory properties in 25 volunteers compared to baseline measurements. ([Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/))

## Questions and answers

### Why is ONE/SIZE Oil Sucker Primer a weak match for sensitive skin?

ONE/SIZE Oil Sucker Primer is a weak match because it focuses on absorbing excess oil with silica rather than addressing redness and irritation. While dimethicone offers general support, this type of makeup primer needs soothing ingredients like Centella Asiatica, cica ceramide, antioxidants, and nourishing oils to truly calm and hydrate sensitive skin.
Sources: [International Journal of Toxicology, 2011](https://pubmed.ncbi.nlm.nih.gov/22247236/)

### Which ingredients make this primer a poor fit for sensitive skin?

This primer is a weak match for sensitive skin because it lacks soothing ingredients that target redness and irritation, relying instead on dimethicone and cyclopentasiloxane which offer only general support. A makeup primer for this skin needs soothing properties, calming extracts like Centella Asiatica, and barrier-repairing components to provide hydration and reduce redness without irritation.
Sources: [International Journal of Toxicology, 2011](https://pubmed.ncbi.nlm.nih.gov/22247236/)

### What does Water do for sensitive skin?

Using cool water for facial cleansing preserves skin barrier integrity and lowers skin surface pH in healthy adults. This helps keep skin calm and hydrated without causing the irritation associated with warmer water.
Sources: [International Journal of Cosmetic Science, 2026](https://pubmed.ncbi.nlm.nih.gov/42722630/)

### What does Dimethicone do for sensitive skin?

Dimethicone helps protect sensitive skin against irritants and can keep it feeling calm and comfortable. It is generally well tolerated and unlikely to cause adverse reactions on delicate or reactive skin.
Sources: [Ostomy/wound Management, 2005](https://pubmed.ncbi.nlm.nih.gov/16439809/), [Military Medicine, 2024](https://pubmed.ncbi.nlm.nih.gov/38771104/)

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

This makeup primer goes in the morning routine after your moisturizing sunscreen, though it is a weak match for sensitive skin because it does not target redness or irritation. A product for this skin needs soothing and calming ingredients to manage sensitivity and ease irritation.

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

You can use this makeup primer with salicylic acid by applying your salicylic acid treatment first, letting it dry completely, and then smoothing on the primer. This product is safe for sensitive skin as it lacks harsh ingredients, but because it does not address redness and irritation, sensitive skin needs a product of this type that also includes calming ingredients and barrier-supporting ceramides to keep skin comfortable.

### How often should I use this primer?

You can use this makeup primer as often as you like for your makeup routine, since it lacks harsh ingredients and is unlikely to cause irritation on sensitive skin. However, because it only offers general smoothing and does not target redness, sensitive skin needs a product that includes calming ingredients and redness-reducing soothing agents.
Sources: [International Journal of Toxicology, 2011](https://pubmed.ncbi.nlm.nih.gov/22247236/)

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

This primer is unlikely to cause irritation on sensitive skin since it lacks harsh ingredients, but it does not address redness and irritation concerns. A product of this type needs soothing ingredients to calm sensitive skin.
Sources: [International Journal of Toxicology, 2011](https://pubmed.ncbi.nlm.nih.gov/22247236/)

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

Yes, it has no fragrance and no drying alcohol.
