- 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.

([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/))
- 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.

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

This treatment goes in the evening routine for combination skin. Lovi routines place serums with actives in the evening for simplicity and extra safety around sun exposure.

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

You can use this serum with retinol by applying this treatment first and following with your retinol on alternate nights or in separate routines to avoid irritation. This product is unlikely to cause irritation due to the absence of harsh ingredients, but combination skin needs lightweight hydration and brightening ingredients like niacinamide and glycerin to stay balanced.
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/)

### How often should I use it?

You can use this treatment in your evening routine, applying it after cleansing and before moisturizing. To better fit combination skin, a product of this type needs antioxidants and hydrators like niacinamide and glycerin to manage oily shine while keeping the skin soft and smooth.

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

Olay Vitamin C Serum is unlikely to cause breakouts or clog pores on combination skin, as it has a very safe formula with no harsh or heavy ingredients. However, to truly balance oily shine and keep combination skin clear, a product of this type needs lightweight hydration alongside gentle pore-clearing ingredients like salicylic acid.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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