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 moisturizers fit it better.

## Why this fit

- Offers moderate suitability for your oily skin as glycerin and butylene glycol provide humectant action, but the peptides present are not specialized for oil control, making the benefits largely supportive rather than directly addressing oily shine.
- The serum provides excellent plumping and firming benefits due to acetyl hexapeptide-8 and palmitoyl tripeptide-1, which improve skin volume and elasticity.
- The safety profile is good, with no risks of irritation for your oily skin due to the absence of harsh ingredients and the presence of soothing components like glycerin.

- A multi-modal methodology combining MALDI-MSI, in vivo RCM, echography, and histology revealed age-related decreases in extracellular matrix and epidermal-dermal junction proteins and undulation depth, while a blend of palmitoyl oligopeptide and palmitoyl tetrapeptide-7 improved subepidermal low-echogenic band thickness, density, and extracellular matrix structure compared to placebo.

## Questions and answers

### How well does The Inkey List Collagen Peptide Serum work for oily skin?

This serum works moderately well for oily skin because its ingredients hydrate nicely without causing irritation, though it lacks oil-controlling benefits. It provides firming support, but a product for this skin type also needs ingredients like hyaluronic acid for hydration, niacinamide to regulate oil and shrink pores, and soothing components like allantoin for balance.
Sources: [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/), [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/)

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

Glycerin and butylene glycol make this serum a fit for oily skin by drawing in moisture without feeling heavy. Oily skin also needs ingredients like hyaluronic acid to provide balanced hydration and niacinamide to help control shine and minimize pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What do Collagen Peptides do for oily skin?

Collagen peptides help balance sebum production while improving skin hydration and elasticity. Taking them daily may support overall skin health and help keep your skin looking smooth and firm.
Sources: [Oxidative Medicine and Cellular Longevity, 2016](https://pubmed.ncbi.nlm.nih.gov/26904164/), [Journal of Cosmetic Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/26362110/)

### What does Argireline do for oily skin?

Argireline is generally safe for oily skin, but it is primarily used for anti-aging and smoothing wrinkles rather than controlling oil. To properly care for oily skin while targeting signs of aging, this type of product needs a lightweight, oil-free formula that hydrates without feeling heavy.

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

This serum goes in the evening routine after cleansing and toning, and before moisturizing. Oily skin works better with products that include oil-controlling ingredients to manage shine.

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

You can use this serum with retinol by applying the serum first to help keep your skin comfortable and smooth, followed by the retinol. This type of routine for oily skin needs ingredients that also help control shine and balance oil production.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this serum?

You can use this serum in the evening as part of your routine. It is unlikely to irritate oily skin, but to truly fit this skin well, a product of this type needs oil-control ingredients that manage shine.

### 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 because it has a safe formula free of harsh ingredients and includes soothing glycerin. However, because it lacks oil control ingredients, oily skin types often need a formula with mattifying minerals or balancing acids to keep shine in check.

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

Yes, you can use this serum around the eyes and on your body because its gentle formula has a good safety profile and is unlikely to cause irritation. Oily skin around the eyes and body needs lightweight moisture and firming ingredients like glycerin and peptides to keep skin smooth and plump.
Sources: [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/), [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/)

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

Yes, it has no fragrance and no drying alcohol.
