## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Capryloyl salicylic acid peel reduced fine lines, wrinkles, and hyperpigmentation comparably to glycolic acid peel in 44 female volunteers, with no statistically significant differences between the two treatments. ([Journal of Cosmetic Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/19146601/))
- Daily treatment with a facial serum containing multiple acids reduced post-inflammatory hyperchromia lesion grade and number by 29.4% at 56 days, and decreased skin oiliness by 30.7% at 7 days in Brazilian patients with acne vulgaris. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/))
- Repeated short-contact 70% glycolic acid peels provided superior results in atrophic acne scars compared to daily low-strength glycolic acid cream or placebo in 58 women over 24 weeks. ([International Journal of Dermatology, 2000](https://pubmed.ncbi.nlm.nih.gov/11095203/))
- Serial glycolic acid peels combined with a modified Kligman formula significantly reduced facial PIH severity in Indian patients compared to the modified Kligman formula alone. ([Dermatologic Surgery, 2017](https://pubmed.ncbi.nlm.nih.gov/28114204/))
- 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/))
- 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/))
- 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 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/))
- Combining a salicylic acid and lipohydroxy acid facial serum and mask improved closed comedones and acne severity significantly more than serum alone in adults with acne over 8 weeks, with no adverse reactions reported. ([Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36999489/))

## What reviewers say

Based on a very large amount of data, this serum is highly rated by users with oily, acne-prone, and textured skin for its ability to rapidly reduce breakouts and smooth skin surface. While effective for many in clearing congestion and tightening pores, a notable minority of users experience purging, stickiness, or irritation due to its potent acid blend.

## Questions and answers

### What makes La Roche-Posay Effaclar Ultra Concentrated Serum a great fit for skin with dark spots?

This serum is a great fit for skin with dark spots because glycolic acid, salicylic acid, and capryloyl salicylic acid help renew skin texture and fade dark spots, while niacinamide makes skin brighter and smoother. It is unlikely to cause irritation and has a safe profile for normal skin.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/19146601/)

### Which ingredients make this serum a good fit for skin with dark spots?

Glycolic acid, salicylic acid, and capryloyl salicylic acid help renew skin texture and fade dark spots, while niacinamide helps make skin brighter and more even. Using these acids together helps reduce stubborn dark spots and promotes a smooth, clear look.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/), [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/)

### What does Glycolic Acid do for skin with dark spots?

Glycolic acid helps fade dark spots and improves uneven skin tone by encouraging the shedding of pigmented surface cells. When used in treatments or peels alongside other brightening ingredients, it may further reduce the severity of stubborn discoloration.
Sources: [Dermatologic Surgery, 1999](https://pubmed.ncbi.nlm.nih.gov/10417583/), [The Journal of Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17204097/)

### What does Salicylic Acid do for skin with dark spots?

Salicylic acid helps fade dark spots and uneven skin tone left behind after breakouts. It gently clears away surface buildup, which may improve the look of dark marks and support a smoother, more even complexion over time.
Sources: [Dermatologic Surgery, 2009](https://pubmed.ncbi.nlm.nih.gov/19400885/), [Dermatologic Surgery, 1999](https://pubmed.ncbi.nlm.nih.gov/9935087/)

### Where does it go in a skincare routine for skin with dark spots?

This exfoliant treatment goes in your evening routine after cleansing and before moisturizing, starting just once a week so your skin can adjust. Lovi routines put treatments 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 in your evening routine, but it is best to alternate nights with your retinol to keep your skin calm and smooth. Using both exfoliating acids and retinoids at the same time may easily lead to dryness or irritation.

### How often should I use it?

Start by using this treatment once a week in the evening, and if your skin feels comfortable and you see good results, you can carefully use it more often. It helps smooth skin texture and renew dark spots with a very safe profile.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32356917/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38406974/)

### Can this serum clog pores, cause breakouts or purging for skin with dark spots?

This serum helps smooth skin texture and renew skin, but reviewers report moderate initial breakouts because its acids clear out congestion. It is unlikely to cause lasting irritation or clogged pores since it avoids harsh ingredients.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/)

### Is it fragrance-free and alcohol-free?

It contains fragrance (parfum) and drying alcohol (alcohol denat).
