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

Brand: [COSRX](https://lovi.care/skincare/uk/brands/cosrx)
Category: [Serums and treatments](https://lovi.care/skincare/uk/best/serums)

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.

A weak match for oily skin; the serums alongside fit it better.

## Why this fit

- Offers moderate treatment for minimizing fine lines and wrinkles due to the presence of retinol, which promotes skin renewal and is highly suitable for your oily skin by regulating desquamation. Tocopherol also provides antioxidant activity to protect your skin.
- While retinol offers benefits for oily shine, it may indirectly pose risks of worsening the condition, so careful monitoring is advised.

## What the research says

- 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/))
- Topical 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle. ([International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/))
- 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/))
- Topical stabilized retinol treatment induced HAS gene expression and increased hyaluronic acid production in human skin in vitro, ex vivo, and in vivo compared to vehicle. ([Archives of Dermatological Research, 2017](https://pubmed.ncbi.nlm.nih.gov/28247017/))
- Squalane at 0.005-0.015% counteracts UVA-induced oxidative stress, inflammation, and collagen metabolism inhibition while stimulating fibroblast migration in human dermal fibroblasts. ([Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/))
- Plant-derived squalane protected human dermal fibroblasts against UVA-induced damage by counteracting ROS formation, suppressing apoptosis-related proteins p53, caspase-3, caspase-9, and PARP, and restoring the pro-survival p-Akt/mTOR pathway. ([Antioxidants, 2025](https://pubmed.ncbi.nlm.nih.gov/40722956/))
- Topical application of an antioxidant serum containing 15% ascorbic acid, 0.5% ferulic acid, and 1% tocopherol prevented particulate matter-induced degradation of extracellular matrix components, inflammation, and oxidative stress in the skin of 15 female volunteers compared to untreated controls. ([Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40642809/))
- Dermatological products containing d-alpha tocopheryl acetate showed non-comedogenic potential with less than a 50% increase in microcomedones in 12 healthy male subjects compared to octyl palmitate. ([Contemporary Clinical Trials Communications, 2021](https://pubmed.ncbi.nlm.nih.gov/34471722/))
- Topical application of an antioxidant mix containing 15% ascorbic acid, 0.5% ferulic acid, and 1% tocopherol prevented PM and UV-induced skin barrier perturbation, lipid peroxidation, inflammatory markers, MMP9 activation, and Type I collagen loss in 15 healthy females compared to untreated exposed skin.

## What reviewers say

Based on a very large amount of data, users with dry, mature, or sensitive skin highly praise this oil for its gentle yet effective formula, noting significant improvements in skin texture, radiance, and fine lines without irritation. The rich oil base can be too heavy for oily or acne-prone skin types, leading to congestion, and many users find the short three-month shelf life after opening to be a major inconvenience.

- Liked: Deeply moisturizing (often mentioned)
- Liked: Gentle & non-irritating (often mentioned)
- Disliked: Short shelf life (often mentioned)
- Liked: Effective on fine lines (sometimes noted)
- Liked: Improves texture & glow (sometimes noted)
- Disliked: Heavy for oily skin (sometimes noted)
- Disliked: Packaging issues (rarely noted)
- Disliked: Unpleasant scent (rarely noted)

## How to apply

- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.

## Questions and answers

### Why is COSRX The Retinol 0.5 a weak match for oily skin?

COSRX The Retinol 0.5 is a weak match for oily skin because, while the retinol helps renew your skin and smooth fine lines, it may indirectly worsen oily shine and requires careful monitoring. A treatment of this type needs ingredients like niacinamide, ferulic acid, and zinc PCA to control oil and pores, along with ceramides and soothing extracts for comfort.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Which ingredients make this cream a poor fit for oily skin?

This treatment is a weak match for oily skin because the heavy oils like soybean oil and squalane may increase excess shine, so careful monitoring is advised. A product of this type for oily skin needs ingredients like niacinamide, zinc PCA, and ferulic acid to control sebum and pores comfortably without causing breakouts or irritation.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### What does Retinol do for oily skin?

Retinol helps oily skin by keeping pores clear and balancing sebum production, which may reduce shine and breakouts. Because it can sometimes cause dryness or peeling in the beginning, starting slowly is recommended.
Sources: [Biochimica Et Biophysica Acta, 2012](https://pubmed.ncbi.nlm.nih.gov/21914489/)

### What does Squalane do for oily skin?

Squalane helps keep oily skin soft and smooth without feeling heavy, though oxidized forms may sometimes trigger irritation. To work well for oily skin, this type of product needs lightweight, non-clogging ingredients that balance moisture without adding excess grease.
Sources: [The Journal of Investigative Dermatology, 2006](https://pubmed.ncbi.nlm.nih.gov/16778793/)

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

This treatment goes in the evening routine after cleansing and toning, and before moisturizing, but it is a weak match for oily skin because retinol may worsen oily shine. An oily skin product of this type needs lightweight hydrators and oil-controlling ingredients like niacinamide.

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

This product is a weak match for your oily skin, so you should monitor how your skin reacts when combining active ingredients. When using potent treatments alongside vitamin C, apply the vitamin C in your morning routine and save this treatment for your evening routine to help prevent irritation. Oily skin requires lightweight, balancing ingredients that control excess shine without causing irritation or worsening breakouts.

### How often should I use this cream?

This treatment is best used in the evening, starting just once a week and very carefully building up frequency only if your oily skin tolerates it well. Because it contains retinol, it may occasionally worsen oily shine or cause irritation, so careful monitoring is advised. An oily skin type needs lightweight treatments and oil-free hydrators with balancing and clarifying ingredients like niacinamide, salicylic acid, or lightweight hyaluronic acid.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

This product is a weak match for oily skin because reviewers frequently note that it feels heavy, and while retinol helps renew skin, the oil-heavy formula may make oily shine worse. A treatment for this skin needs lightweight, non-greasy hydrators and clear pores without heavy oils.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
