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

Brand: [Olay](https://lovi.care/skincare/sg/brands/olay)
Category: [Serums and treatments](https://lovi.care/skincare/sg/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.

Works for oily skin; other serums fit it better.

## Why this fit

- Offers excellent treatment for fine lines and wrinkles due to retinol and retinyl propionate, which are beneficial for your oily skin by regulating desquamation.
- Niacinamide further supports seboregulation, though the inclusion of dimethicone and glycerin primarily addresses general hydration rather than your specific concern of oily shine.
- The product is safe for your oily skin, with no risks of irritation from harsh ingredients.

- Topical application of all-trans-retinol induced epidermal thickening and increased retinoid binding protein expression similar to all-trans-retinoic acid in normal human skin, but without causing significant erythema or measurable retinoic acid levels. ([The Journal of Investigative Dermatology, 1995](https://pubmed.ncbi.nlm.nih.gov/7561157/))
- Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin.

- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects.

- 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 serums fit oily 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/))
- Niacinamide and ferulic acid incorporated in a stable multiple emulsion successfully reduced melanin, sebum, and skin erythema while improving skin elasticity and hydration in human skin compared to a placebo. ([BioMed Research International, 2022](https://pubmed.ncbi.nlm.nih.gov/35342760/))

## What reviewers say

Users consistently praise this serum for its gentle, non-drying formula that leaves skin feeling silky and hydrated, making it an excellent choice for retinol beginners.

## 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

### How well does Olay Retinol 24 work for oily skin?

Olay Retinol 24 Night Serum works reasonably well for oily skin, helping smooth fine lines without causing irritation, though other options target shine and oil control more directly. To truly excel on oily skin, a product of this type needs ingredients like niacinamide, zinc, or specific soothing extracts that actively manage excess oil and reduce enlarged pores.
Sources: [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/)

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

Retinol, retinyl propionate, and niacinamide make this serum a good fit for oily skin by helping to regulate cell turnover and control oil. To fit oily skin even better, a treatment of this type needs ingredients like ferulic acid, zinc PCA, and soothing extracts that specifically manage excess shine and large pores while keeping the skin comfortable.
Sources: [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/)

### 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 Niacinamide do for oily skin?

Niacinamide helps balance oily skin by significantly reducing excess oil production and shine. It is well tolerated and may improve skin texture without clogging pores.
Sources: [Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

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

This serum goes in the evening routine after cleansing and toning, followed by a moisturizer. Putting treatments in the evening provides extra safety around sun exposure, and this product is safe for oily skin with no risks of irritation from harsh ingredients.

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

You can use this serum with vitamin C by applying vitamin C in your morning routine and this serum at night. This helps you get the smoothing benefits of both ingredients without overwhelming your skin with too many active treatments at the same time.

### How often should I use this serum?

Use this serum in your evening routine, applying it once a day to help smooth fine lines safely. Oily skin often benefits from lightweight treatments containing oil-controlling and pore-clearing ingredients like niacinamide and retinol.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

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

This serum is unlikely to cause breakouts or clog pores on oily skin, and it has a very safe profile with no harsh ingredients to cause irritation. However, it may cause mild purging when you first start using it as the retinol speeds up your skin renewal. Oily skin works best with lightweight ingredients that help control shine and balance oil without adding extra heaviness.
Sources: [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/)

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

It has no drying alcohol and contains fragrance (benzyl alcohol).
