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 treatment for acne-prone skin, as salicylic acid and niacinamide effectively reduce acne lesions and blemishes, while glycerin and dimethicone provide hydration and emollience that are generally suitable for combination skin.
- The formulation is safe for your combination skin, lacking harsh ingredients that could cause irritation.
- While the product offers general skincare benefits, its primary focus on acne treatment may not fully address your specific concern of oily shine.

## What the research says

- 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/))
- A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase. ([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))
- Twice daily application of a multitargeted dermocosmetic cream provided comparable efficacy to benzoyl peroxide 5% gel in reducing inflammatory, non-inflammatory, and total lesions in 150 Caucasian subjects with mild-to-moderate acne over 56 days, while demonstrating superior skin tolerability. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/))
- The use of a salicylic acid-based dermocosmetic significantly reduces the needed quantity of benzoyl peroxide without impacting efficacy in mild to moderate acne, and as maintenance post-benzoyl peroxide allows a significant reduction of acne relapse compared to vehicle. ([Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38051857/))
- 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/))
- Zinc PCA inhibits UVA-induced matrix metalloproteinase-1 production through suppressed AP-1 activation and enhances type I collagen synthesis by increasing SVCT2 mRNA expression in cultured normal human dermal fibroblasts. ([International Journal of Cosmetic Science, 2012](https://pubmed.ncbi.nlm.nih.gov/21834944/))
- Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients. ([CMAJ, 2010](https://pubmed.ncbi.nlm.nih.gov/20837684/))
- Treatment with 2% supramolecular salicylic acid hydrogel resulted in a regression and markedly improvement rate of 51.01% compared to 43.10% for Adapaline gel in patients with mild to moderate facial acne vulgaris, showing no significant difference in efficacy. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38590107/))
- Topical 5% benzoyl peroxide plus salicylic acid achieved the greatest lesion reduction at early 2 to 4 week time points compared to benzoyl peroxide, clindamycin, and combination benzoyl peroxide/clindamycin, while 5% benzoyl peroxide plus salicylic acid and combination benzoyl peroxide/clindamycin showed similar efficacy at 10 to 12 weeks in acne patients. ([Journal of the American Academy of Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20488582/))

## Why other serums fit combination skin better

- A panthenol-enriched mask improved skin hydration, regulated sebum, and reduced redness and TEWL across dry sensitive, oily sensitive, and oily acne skin subgroups with excellent tolerance and no adverse reactions. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38366684/))

## Questions and answers

### How well does La Roche-Posay Effaclar Duo (+) work for combination skin?

This product works decently for combination skin by treating blemishes while keeping dry areas soft with glycerin and dimethicone, though other options may control oily shine better. Combination skin of this type needs products that regulate oiliness, enhance radiance, and provide balanced hydration without causing excess oiliness or dryness.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/)

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

Salicylic acid and niacinamide help clear blemishes while glycerin and dimethicone provide suitable hydration for combination skin. To best fit this skin type, a product of this type needs ingredients like niacinamide and propolis or zinc PCA that regulate oiliness, enhance radiance, and provide optimal hydration without causing excess oiliness or dryness.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/)

### What does Niacinamide do for combination skin?

Niacinamide helps balance oily areas by reducing excess shine and pore size while keeping dry patches hydrated and smooth. It also works to calm redness and even out skin tone, making it very suitable for combination skin.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

### What does Zinc PCA do for combination skin?

Zinc PCA helps keep combination skin clear by balancing oil and calming redness. This ingredient is unlikely to irritate your skin and works well to reduce blemishes in oily areas without drying out your face.
Sources: [The Journal of Clinical and Aesthetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32983333/), [Journal of Drugs in Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23652948/)

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

This cream is used as a treatment step in the evening routine. Treatments like this go after cleansing and toning, and right before applying your moisturizer.

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

You can use this treatment with retinol by applying the retinol first, letting it dry, and then following with this product to help keep your skin comfortable. Because this is an average fit for your skin, a product for combination skin also needs oil-controlling ingredients to properly target shine.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38102855/)

### How often should I use this cream?

You can use this treatment in the evening as part of your routine. Combination skin needs ingredients like niacinamide and salicylic acid to help clear blemishes, along with lightweight hydrators like glycerin that keep skin soft without feeling heavy.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/), [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38051857/)

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

This treatment is unlikely to cause harsh irritation on combination skin, but new formula breakouts and dryness or peeling may happen for some users. Combination skin of this type needs lightweight hydration and ingredients that balance oil without heavy oils that clog pores.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/), [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38051857/)
