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

Brand: [RoC](https://lovi.care/skincare/ca/brands/roc)
Category: [Moisturizers and moisturizing serums](https://lovi.care/skincare/ca/best/moisturizers)

This fit is calculated for the concerns frequently associated with combination skin: an oily T-zone, enlarged pores, and dry cheeks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

A weak match for combination skin; the moisturizers alongside fit it better.

## Why this fit

- Offers moderate moisturizing for your combination skin due to the presence of hyaluronic acid and glycerin, which hydrate drier areas without overwhelming oilier zones.
- While supportive for oily shine, the formulation lacks targeted ingredients to fully address this primary concern.
- The product is safe for your combination skin, with no risks of irritation from harsh ingredients.

## Key ingredients

Hyaluronic Acid, Hydrolyzed Haematococcus Pluvialis Extract, Astaxanthin Extract

## 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/))
- Astaxanthin-loaded polyhydroxybutyrate microbeads achieved 98.1% encapsulation efficiency with sustained release, reduced degradation by 2-fold compared to unencapsulated astaxanthin, and showed no cytotoxicity or skin irritation in human cells and tests. ([International Journal of Biological Macromolecules, 2024](https://pubmed.ncbi.nlm.nih.gov/38072340/))
- Twice-daily application of a novel topical antioxidant formulation safe, well-tolerated, and effective in improving overall skin quality, fine lines, wrinkles, radiance, and hyperpigmentation in 32 healthy female subjects over 12 weeks. ([Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37608511/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction. ([Clinical Oral Investigations, 2022](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days. ([BMC Oral Health, 2019](https://pubmed.ncbi.nlm.nih.gov/31311529/))
- Oral astaxanthin supplementation significantly restored moisture content and improved elasticity but did not significantly decrease wrinkle depth compared to placebo in humans. ([Nutrients, 2021](https://pubmed.ncbi.nlm.nih.gov/34578794/))
- Combining oral and topical astaxanthin in 30 healthy females improved skin wrinkles, age spots, elasticity, texture, and moisture, while 6 mg daily oral supplementation in 36 healthy males improved crow's feet wrinkles, elasticity, and transepidermal water loss. ([Acta Biochimica Polonica, 2012](https://pubmed.ncbi.nlm.nih.gov/22428137/))
- Astaxanthin prevents UV-induced cutaneous inflammation, abnormal keratinization, wrinkling, and pigmentation in human skin even when applied postirradiation. ([Photochemistry and Photobiology, 2019](https://pubmed.ncbi.nlm.nih.gov/30338860/))

## Why other moisturizers fit combination skin better

- A panthenol-enriched mask improved skin hydration, regulated sebum, and reduced redness and TEWL across dry sensitive, oily sensitive, and oily acne skin subgroups with excellent tolerance and no adverse reactions. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38366684/))
- A peel-off facial mask containing myoinositol and trehalose-loaded liposomes improved adult female acne by decreasing lesion counts, sebum production, GAGS scores, and local androgen levels while increasing beclin-1 levels. ([Journal of Cosmetic Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28342238/))
- Gluconolactone chemical peels lower skin pH and transepidermal water loss while demonstrating seboregulatory properties in 16 female subjects. ([Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37335807/))

## Questions and answers

### Why is RoC Hydration + Serum a weak match for combination skin?

RoC Hydration + Serum is a weak match for combination skin because it offers moderate moisture for drier areas using hyaluronic acid and glycerin, but it lacks the targeted oil-control ingredients needed to fully manage oily shine. A product of this type needs effective hydrating and skin-repairing ingredients like ceramides, peptides, and niacinamide to keep the complexion balanced.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this treatment a poor fit for combination skin?

This treatment is a weak match for your combination skin because it lacks targeted ingredients to fully manage oily shine. A product of this type needs effective hydrating and skin-repairing ingredients like ceramides, niacinamide, or peptides to maintain a balanced and radiant complexion without causing excess oiliness.

### What does Hyaluronic Acid do for combination skin?

Hyaluronic acid is a great fit for combination skin because it quenches dry areas with a boost of hydration while keeping oily zones balanced. Regular use helps smooth out fine lines and makes your skin feel soft and plump without causing irritation.
Sources: [Dermatology and Therapy, 2021](https://pubmed.ncbi.nlm.nih.gov/34176098/), [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/)

### What does Hydrolyzed Haematococcus Pluvialis Extract do for combination skin?

Hydrolyzed Haematococcus Pluvialis Extract helps protect combination skin from sun-induced damage and reduces the appearance of fine lines. It works by fighting oxidative stress and supporting firmness, though individual results may vary.
Sources: [International Journal of Molecular Sciences, 2017](https://pubmed.ncbi.nlm.nih.gov/28327532/), [Antioxidants, 2025](https://pubmed.ncbi.nlm.nih.gov/40427459/)

### Where does this treatment go in a skincare routine for combination skin?

This treatment goes in the evening routine after cleansing and before your moisturizer. Combination skin needs a product of this type that also includes targeted balancing ingredients to control oily shine while keeping drier areas soft.

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

You can use this treatment with retinol by applying it after your retinol product to help keep your skin comfortable and hydrated. This type of product needs extra ingredients that balance oil production and target shine to properly care for combination skin.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this treatment?

This treatment is intended for evening use in your combination skin routine, applied after cleansing and before your moisturizer. A product of this type needs targeted ingredients to fully address oily shine while providing moderate hydration for your combination skin.

### Can it clog pores, cause breakouts or purging for combination skin?

This product is unlikely to clog pores or cause breakouts on your combination skin. It has a safe formula with a low risk of irritation, though a product of this type needs more oil-balancing ingredients to fully manage shine.
Sources: [International Journal of Biological Macromolecules, 2024](https://pubmed.ncbi.nlm.nih.gov/38072340/), [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37608511/)

### Can I use this treatment around the eyes or on my body?

You can safely use this treatment around your eyes and on your body, as it has a very good safety profile and is unlikely to cause irritation. Because the skin around your eyes is among the thinnest on the body, gentle hydrating ingredients like hyaluronic acid help keep it soft.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [Polymers, 2023](https://pubmed.ncbi.nlm.nih.gov/37896378/)
