This fit is calculated for the concerns frequently associated with acne-prone skin: breakouts, blackheads, and post-acne marks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for acne-prone skin; other serums fit it better.

## Why this fit

- Offers moderate brightening for your combination skin as diglucosyl gallic acid and niacinamide help even skin tone and provide antioxidant activity. Glycerin and shea butter offer hydration and soothing benefits for your acne, blemishes, and breakouts.
- The formula is safe for your combination skin with no risks of irritation due to the absence of harsh ingredients.
- While it provides general skincare benefits and moderate brightening, it lacks sufficient ingredients for optimal oil control on your oily areas.

## Key ingredients

Niacinamide, Diglucosyl Gallic Acid, Terminalia Ferdinandiana Fruit Extract, Vitis Vinifera Seed Oil Grape Seed Oil, Resveratrol

## 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/))
- Diglucosyl gallic acid exhibits stronger tyrosinase inhibition than VC with an IC50 of 2.68 mg/mL, and its application as a cosmetic ingredient improves skin brightness while reducing ultraviolet spots, melanin, and erythema in human volunteers. ([International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/))
- 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/))
- Grapeseed oil-loaded dermocosmetic nanoemulgel applied on the cheeks of healthy volunteers significantly reduced skin melanin, erythema, sebum production, and pores while increasing moisture and elasticity compared to a placebo. ([Journal of Cosmetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35713012/))
- Topical treatment with cranberry oil and grape oil improved wound healing in rats, with cranberry oil showing an 88.1% wound area reduction and grape oil showing 84.6% compared to 74.1% in controls and 78.4% in the mupirocin standard group on day 13. ([Phytotherapy Research, 2011](https://pubmed.ncbi.nlm.nih.gov/21305631/))
- An ionic liquid-based grapeseed oil emulsion increased transdermal penetration by 4.63-fold and improved skin hydration, firmness, elasticity, and facial wrinkles after 28 days of continuous use compared to ordinary emulsion. ([Pharmaceuticals, 2024](https://pubmed.ncbi.nlm.nih.gov/39458914/))
- Topical CE Ferulic plus resveratrol BE serum following ablative fractional CO2 laser treatment reduced erythema index (308.9 vs. 325.3), shortened complete scabbing detachment time (6.0 vs. 6.5 days), decreased melanin index (-7.4% vs. +0.2%), and improved skin hydration compared to normal saline in 51 Chinese patients. ([Journal of the European Academy of Dermatology and Venereology, 2024](https://pubmed.ncbi.nlm.nih.gov/38828801/))
- Topical treatment with a combination of pyridine-2, 4-dicarboxylic acid diethyl ester and resveratrol significantly increased hair density in 79 Caucasian female subjects starting from 1.5 months compared to baseline. ([International Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/31960447/))
- A nighttime topical antioxidant containing resveratrol, baicalin, and vitamin E significantly improved fine lines, wrinkles, firmness, elasticity, laxity, hyperpigmentation, radiance, roughness, and dermal thickness in subjects with mild to moderately photodamaged skin over 12 weeks. ([Journal of Drugs in Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/25607790/))

## Why other serums fit acne-prone 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/))
- A cream combining propolis, tea tree oil, and Aloe vera reduced erythema scars, acne severity index, and total lesion count better than erythromycin cream in sixty patients with mild to moderate acne vulgaris compared to placebo. ([Clinical Pharmacology, 2018](https://pubmed.ncbi.nlm.nih.gov/30588129/))
- Topical nicotinamide plus an antibacterial adhesive agent and zinc-pyrrolidone carboxylic acid combined with adapalene significantly reduced noninflammatory acne lesions by the second week of therapy compared to placebo with adapalene in patients with moderate acne vulgaris.

## Questions and answers

### How well does Gundry MD Polyphenol Dark Spot Diminisher work for acne-prone skin?

Gundry MD Polyphenol Dark Spot Diminisher works moderately well for acne-prone skin, offering helpful brightening and soothing hydration without causing irritation. However, it lacks sufficient oil-control ingredients for oily areas. Acne-prone skin needs products containing ingredients like zinc PCA and propolis to balance oil and manage breakouts effectively.

### Which ingredients make this cream a good fit for acne-prone skin?

Diglucosyl gallic acid and niacinamide help even skin tone, while glycerin and shea butter offer hydration and soothing benefits for blemishes. However, acne-prone skin needs additional ingredients like propolis or zinc PCA to provide optimal oil control and balance.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/)

### What does Niacinamide do for acne-prone skin?

Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38299457/), [Cureus, 2024](https://pubmed.ncbi.nlm.nih.gov/38725769/)

### What does Diglucosyl Gallic Acid do for acne-prone skin?

Diglucosyl gallic acid helps brighten skin and fade dark spots, but acne-prone skin also needs ingredients that clear pores and calm redness.
Sources: [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31584241/)

### Where does it go in a skincare routine for acne-prone skin?

This treatment goes in your evening routine after cleansing and before moisturizing. A product for this skin needs extra oil-controlling ingredients to manage oily areas.

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

You can use this treatment alongside retinol by applying the retinol first at night and following it with this cream to keep your skin calm and hydrated. Because this product lacks oil control, acne-prone skin needs a product with ingredients that balance oil production and clear pores.

### How often should I use it?

You can use this treatment in the evening as part of your routine. It is safe for your skin with no risks of irritation, though acne-prone skin needs extra ingredients for oil control.

### Can this cream clog pores, cause breakouts or purging for acne-prone skin?

This treatment is unlikely to cause irritation on your acne-prone skin since the formula leaves out harsh ingredients. However, it may not work as well as other products for this skin type because it lacks enough oil-controlling ingredients to properly manage oily areas.

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

It has no drying alcohol and contains fragrance (parfum).
