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 tretinoin and azelaic acid promote skin renewal and regulate melanogenesis to target pigmentation and acne lesions.
- The formula provides excellent treatment for acne lesions and blemishes, though it lacks sufficient humectant and emollient ingredients for optimal results.
- The safety profile is excellent, with no risks of irritation due to the absence of prohibited or harsh ingredients.

([Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/))
- Azelaic acid nanocrystal hydrogel 10% achieved a higher success rate and greater lesion reduction than azelaic acid cream 20% in patients with mild to moderate facial acne. ([Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33923739/))
- Tretinoin-loaded nano lipid carriers resulted in a significantly higher rate of decrease in acne lesions and greater reduction in porphyrin production compared to conventional tretinoin cream in patients with mild to moderate acne vulgaris. ([Archives of Dermatological Research, 2022](https://pubmed.ncbi.nlm.nih.gov/34146120/))
- A galenic compound containing essential oils and tretinoin demonstrated anti-acne efficacy and anti-inflammatory activity, significantly reducing papular erythema and retinoid-induced rashes compared to clindamycin-tretinoin gel in sixty volunteers over 30 days. ([Clinical, Cosmetic and Investigational Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32210603/))
- Once-daily fixed-dose clindamycin phosphate 1.2%/benzoyl peroxide 3.1%/adapalene 0.15% gel achieved superior treatment success (52.5%) and greater reductions in inflammatory and noninflammatory lesions compared to vehicle (8.1%) and dyad component gels in participants with moderate-to-severe acne over 12 weeks. ([American Journal of Clinical Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/34674160/))

- Topical tretinoin daily application for 10 to 12 months produced an 80 percent increase in collagen I formation in photodamaged human skin compared with a 14 percent decrease with vehicle alone. ([The New England Journal of Medicine, 1993](https://pubmed.ncbi.nlm.nih.gov/8336752/))
- Topical tretinoin precursors and tretinoin showed no significant difference in efficacy for moderate to severe facial photodamage in 20 patients, while tretinoin precursors caused erythema six times less frequently. ([JAMA Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35675051/))

- Azelaic acid 15% gel showed comparable efficacy to adapalene 0.1% gel in reducing lesions, severity, and Dermatology Life Quality Index in women with adult acne, with significantly lower dryness and scaling, and demonstrated superiority during maintenance compared to no further treatment. ([Journal of the European Academy of Dermatology and Venereology, 2015](https://pubmed.ncbi.nlm.nih.gov/25399481/))
- Topical clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide 3.1% gel achieved significantly greater treatment success and lesion reductions compared to vehicle in participants with moderate-to-severe acne.

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

Tretinoin and azelaic acid make this treatment a good fit by promoting skin renewal and targeting dark spots. To fit this skin best, a product of this type needs a blend of effective antioxidants, soothing and hydrating ingredients, and skin-repairing components.
Sources: [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/), [Archives of Dermatological Research, 2022](https://pubmed.ncbi.nlm.nih.gov/34146120/)

### What does Tretinoin do for skin with dark spots?

Tretinoin helps fade dark spots and uneven pigmentation by improving the look of sun-damaged skin over time. It is generally safe and well tolerated, though results depend on consistent application.
Sources: [International Journal of Women's Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35620028/), [Archives of Dermatological Research, 2025](https://pubmed.ncbi.nlm.nih.gov/39833642/)

Azelaic acid helps fade dark spots and uneven skin tone by slowing down the overactive pigment production in your skin cells. It is unlikely to cause irritation and may gradually clear up stubborn marks left behind by breakouts or sun exposure.
Sources: [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/), [Archives of Dermatological Research, 1990](https://pubmed.ncbi.nlm.nih.gov/2114832/)

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

This treatment goes in the evening routine before your moisturizer. Skin with dark spots also needs extra hydrating and softening ingredients to give you the best results.

### Can I use this treatment with niacinamide, and in what order?

You can use this treatment with niacinamide by applying niacinamide first in your routine and following it with this treatment. This combination helps brighten dark spots safely, though this product needs extra hydrating and softening ingredients for the best results on this skin type.
Sources: [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/)

### How often should I use it?

Use this treatment in your evening routine, applying it once a week at first and carefully increasing the frequency if your skin handles it well.

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

This treatment is unlikely to cause breakouts or clog pores on skin with dark spots because it has a very safe formula without harsh ingredients. However, to work best on dark spots, a product of this type needs extra softening and moisture-locking ingredients.
