This fit is calculated for the concerns frequently associated with combination skin: an oily T-zone, enlarged pores, and dry cheeks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for combination skin; other serums fit it better.

## Why this fit

- This serum offers moderate treatment for minimizing fine lines and wrinkles, as retinol and sodium hyaluronate work to smooth texture for your combination skin.
- Glycerin and sodium hyaluronate provide general hydration benefits, which are supportive but not specifically targeted for oily shine on combination skin.
- The safety profile is excellent, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## Questions and answers

### How well does RoC Derm Correxion Fill + Treat Serum work for combination skin?

This serum works moderately well for your combination skin, using retinol and sodium hyaluronate to smooth fine lines while providing gentle hydration. It is safe and unlikely to cause irritation, though it does not specifically target oily shine. Treatments that fit combination skin better need ingredients like niacinamide, propolis, and zinc PCA to regulate oiliness while keeping the skin balanced.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Retinol and sodium hyaluronate make this serum a good fit for combination skin by smoothing texture and providing general hydration. To work best for this skin type, a product of this type needs ingredients like niacinamide, propolis, and zinc PCA to regulate oiliness and balance combination skin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Retinol do for combination skin?

Retinol helps smooth out uneven skin tone, softens fine lines, and keeps pores clear for a balanced look. Because combination skin can sometimes be sensitive or dry in certain areas, starting slowly helps your skin adjust and minimizes any irritation.
Sources: [International Journal of Cosmetic Science, 2008](https://pubmed.ncbi.nlm.nih.gov/18452434/), [The Journal of Clinical and Aesthetic Dermatology, 2016](https://pubmed.ncbi.nlm.nih.gov/27354885/)

### What does Triple Hyaluronic Acid do for combination skin?

Triple Hyaluronic Acid helps combination skin by deeply boosting moisture in dry areas while keeping the face feeling soft and smooth. This ingredient is unlikely to cause irritation and supports a healthy skin barrier.
Sources: [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/), [Journal of Drugs in Dermatology, 2016](https://pubmed.ncbi.nlm.nih.gov/27050698/)

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

This treatment goes in the evening routine for your combination skin. A product of this type for combination skin needs ingredients that smooth fine lines while balancing oily shine.

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

You can use this serum with niacinamide by applying niacinamide first, letting it dry, and then applying this treatment. This combination is unlikely to cause irritation because this product has a very safe formula, but combination skin needs lightweight hydration and ingredients that balance oily shine rather than heavy butters.

### How often should I use it?

This treatment is meant to be used in the evening for simplicity and extra safety around sun exposure, starting once a week and slowly increasing frequency if your skin tolerates it well. Retinol and hydrating ingredients like hyaluronic acid help smooth texture and soften fine lines with a very low risk of irritation.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

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

This serum is unlikely to cause breakouts or clog pores on combination skin, as its safety profile is excellent without harsh ingredients. Retinol may cause mild purging when you first start using it, but it helps smooth your skin texture over time.
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. Stearyl alcohol and cetearyl alcohol are fatty alcohols, which soften the skin.
