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

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

This fit is calculated for the concerns frequently associated with dark spots: hyperpigmentation, sun spots, and uneven skin tone. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for skin with dark spots; other serums fit it better.

## Why this fit

- Offers moderate suitability for normal skin as diglucosyl gallic acid and niacinamide provide antioxidant activity and melanogenesis regulation, but lacks sufficient humectant and emollient ingredients for optimal hydration and barrier support.
- The product provides effective skin brightening due to the presence of diglucosyl gallic acid and niacinamide in moderate concentrations for evening skin tone.
- The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.

## Questions and answers

### How well does Gundry MD Dark Spot Diminisher work for skin with dark spots?

Gundry MD Polyphenol Dark Spot Diminisher works moderately well for skin with dark spots because ingredients like niacinamide and diglucosyl gallic acid help even skin tone and provide antioxidant benefits. However, it lacks enough hydrating and softening ingredients for optimal moisture and barrier support, which a treatment for this skin needs to keep the skin fully hydrated and protected.
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/)

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

Diglucosyl gallic acid and niacinamide make this cream a good fit by helping even out skin tone and reduce dark spots. To fit this skin even better, a product of this type needs stronger hydrating and skin-softening ingredients to fully support the moisture barrier.
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 skin with dark spots?

Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
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 Diglucosyl Gallic Acid do for skin with dark spots?

Diglucosyl gallic acid helps brighten skin and fade dark spots, ultraviolet spots, and redness. It works by blocking the enzyme that causes skin darkening, and it has a very strong antioxidant effect.
Sources: [International Journal of Cosmetic Science, 2022](https://pubmed.ncbi.nlm.nih.gov/35211990/), [Current Pharmaceutical Design, 2018](https://pubmed.ncbi.nlm.nih.gov/30657034/)

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

This treatment goes in the evening routine after cleansing and before your moisturizer. Skin with dark spots also needs plenty of hydrating and softening ingredients to keep the barrier strong while brightening.

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

You can use this treatment with retinol by applying retinol first in your evening routine and following with this cream, or by using them on alternating nights to keep your skin calm. This helps you target dark spots while keeping irritation unlikely, though this skin type needs added soothing hydrators and protective moisturizers to stay soft and smooth.
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/)

### How often should I use this cream?

This treatment is used in the evening as part of your routine for skin with dark spots. An average fit for your skin like this product needs extra hydrating and soothing ingredients to keep skin comfortable while brightening dark spots.
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/)

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

This cream is unlikely to clog pores or cause breakouts for skin with dark spots because it has an excellent safety profile without harsh ingredients. However, because it lacks sufficient soft and smooth moisturizing ingredients, skin with dark spots also needs nourishing hydrators and barrier-supporting emollients to stay healthy.

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

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