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

Category: [Serums and treatments](https://lovi.care/skincare/ie/best/serums)

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

- Offers moderate skin strengthening for your combination skin due to the presence of Panax Ginseng Root Extract and Schisandra Chinensis Fruit Extract, which enhance barrier resilience, but lacks targeted ingredients for your oily shine concerns.
- Glycerin and sodium acetylated hyaluronate provide humectant action, offering general hydration benefits that are supportive but not primary for managing excess oil.
- The formula is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## What the research says

- Exposure of epidermal full-thickness skin equivalents to a blend of betaine, pentylene glycol, Saccharomyces cerevisiae, and Rhodiola rosea root extract significantly increased antioxidant, skin barrier, and oxidative stress biomarkers while reducing the negative impact of hydrogen peroxide on MMP3, MMP12, FBN2, ANXA1, and HGF, whereas a blend of Narcissus tazetta bulb extract and Schisandra chinensis fruit extract significantly increased 8 growth factors, 7 signaling, 7 structural/barrier function, 7 oxidative stress biomarkers, and specific microRNAs over control levels. ([International Journal of Molecular Sciences, 2018](https://pubmed.ncbi.nlm.nih.gov/30373163/))

## What reviewers say

Users frequently praise this serum for its lightweight, milky texture that deeply hydrates and visibly plumps the skin, often noting a "glowy" and more resilient complexion after consistent use. The product is polarizing due to its strong herbal scent and high alcohol/essential oil content, which has caused irritation and breakouts for those with sensitive skin conditions.

## Questions and answers

### How well does Kiehl's Vital Skin-Strengthening Super Serum work for combination skin?

This serum works reasonably well for combination skin by offering moderate skin strengthening and general hydration, though other products fit this skin type better.

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

Panax ginseng root extract and schisandra chinensis fruit extract help strengthen your skin barrier. Additionally, glycerin and sodium acetylated hyaluronate provide general hydration that supports your skin. A product for combination skin of this type needs ingredients like niacinamide and zinc PCA to regulate oily shine and keep the skin balanced.

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

Hyaluronic acid helps combination skin by boosting hydration, smoothing texture, and keeping moisture balanced across dry and oily areas. Clinical studies show it significantly increases skin moisture and improves overall smoothness without causing irritation.
Sources: [Dermatology and Therapy, 2021](https://pubmed.ncbi.nlm.nih.gov/34176098/), [The Journal of Clinical and Aesthetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/32038748/)

### What does Adaptogenic Herbal Complex do for combination skin?

Sources: [Drug Design, Development and Therapy, 2023](https://pubmed.ncbi.nlm.nih.gov/36776447/), [Frontiers in Bioscience, 2023](https://pubmed.ncbi.nlm.nih.gov/38179774/)

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

This treatment goes in the evening routine after cleansing and before moisturizing, though some serums may also be used in the morning or twice a day. Combination skin additionally needs targeted ingredients that help control oily 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 give your skin general hydration before your retinol product. The formula is safe for your combination skin, with no risks of irritation due to the absence of harsh ingredients.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

You can use this serum in your evening routine. Combination skin needs a product of this type that also balances excess oil and targets shine.

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

This serum is unlikely to cause irritation or breakouts on combination skin, as the formula is safe and free of harsh ingredients. However, it lacks targeted ingredients to control oily shine, which means combination skin of this type needs balancing ingredients like niacinamide or clay to properly manage excess oil.

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

It contains fragrance (limonene, eugenol, citral, citronellol, linalool, and geraniol) and drying alcohol (alcohol denat).
