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 moderate brightening and evening of skin tone for your oily skin, as Niacinamide and Ascorbic Acid work to address hyperpigmentation while Hyaluronic Acid provides essential hydration.
- While Glycerin and Ascorbic Acid offer antioxidant support, the formula is not specialized for managing excess oiliness, which is your main goal.
- The product is generally safe for your oily skin, with a low risk of irritation from Ascorbic Acid.

## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/))
- Vitamin C mesotherapy produced a significant and earlier reduction in gingival pigmentation and higher patient satisfaction compared to topical gel in twenty healthy non-smokers with hyperpigmented gingiva, with both methods reducing the mean area fraction of melanin-forming cells at 6 months without causing pain. ([Clinical Oral Investigations, 2021](https://pubmed.ncbi.nlm.nih.gov/33966113/))
- 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/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- 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/))
- 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. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women. ([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- Topical application of 5% vitamin C cream significantly improved global clinical scores, increased skin microrelief density, and induced elastic tissue repair in photoaged skin compared to excipient control in healthy female volunteers. ([Experimental Dermatology, 2003](https://pubmed.ncbi.nlm.nih.gov/12823436/))
- Ascorbic acid 2-glucoside gel significantly reduced gingival melanin pigmentation after 4 weeks compared to placebo in 73 subjects with symmetric pigmentation. ([Journal of Periodontology, 2009](https://pubmed.ncbi.nlm.nih.gov/19186973/))
- Topical application of VC-IP cream twice daily for 8 weeks reduces periorbital wrinkles in female subjects compared to a placebo cream. ([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/34910367/))

## Why other serums fit oily skin better

- 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

Based on a very large amount of data, this serum is frequently praised for its lightweight, non-greasy formula that visibly brightens and hydrates without clogging pores, leading to a healthy glow and smoother texture for many users.

## 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 Vitamin C Serum work for oily skin?

Olay Vitamin C Serum is an average fit for oily skin because it offers moderate brightening and hydration, but it is not specialized for managing excess oiliness. To work better for oily skin, a treatment needs ingredients like niacinamide and zinc to control shine and address enlarged pores.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

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

Niacinamide and Ascorbic Acid make this serum a fit by brightening your skin and helping with uneven tone, while Hyaluronic Acid provides essential hydration. Because it is not specialized for managing excess oiliness, an oily skin product needs ingredients like niacinamide and zinc to control shine and ceramides to support the skin barrier.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/)

### What does Glycerin do for oily skin?

Glycerin helps keep oily skin hydrated without feeling heavy and supports the skin barrier. Because this product is a weak fit for your skin, an ideal product of this type needs lightweight hydrators and ingredients that balance oil while protecting the skin.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [International Journal of Toxicology, 2019](https://pubmed.ncbi.nlm.nih.gov/31840548/)

### 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 your evening routine, as treatments with active ingredients are typically placed there for simplicity and extra safety around sun exposure. While it offers moderate brightening and hydration, it is not specialized for managing excess oiliness, so oily skin also needs products with oil-absorbing and balancing ingredients.

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

You can use this serum with retinol by applying your retinol product first and following with this treatment, or by using retinol at night and this serum in the morning to avoid overloading your skin. This product is generally safe for your oily skin with a low risk of irritation, but an oily skin routine often needs oil-balancing ingredients like salicylic acid or clay to help manage excess oil.

### How often should I use this serum?

You can use this treatment in your evening routine, as this timing offers simplicity and extra safety around sun exposure. For oily skin, this product needs ingredients that actively manage excess oiliness alongside brightening and hydrating components.

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

Olay Vitamin C Serum is unlikely to clog pores or cause breakouts on your oily skin, though it is not specialized for managing excess oiliness. To truly balance oily skin and control shine, you need a lightweight product that specifically targets excess oil with ingredients like salicylic acid or oil-absorbing minerals.

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

Yes, it has no fragrance and no drying alcohol.
