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

Brand: [Curology](https://lovi.care/skincare/ca/brands/curology)
Category: [Serums and treatments](https://lovi.care/skincare/ca/best/serums)

This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

A weak match for sensitive skin; the serums alongside fit it better.

## Why this fit

- Offers moderate benefits for redness and irritation due to azelaic acid, but tretinoin and clindamycin may pose risks of worsening sensitivity in concentrations that can cause irritation for your normal skin with sensitivity.
- The keratolytic action and melanogenesis regulation from tretinoin and azelaic acid offer some benefits for normal skin, but additional hydrating ingredients would better address your skin's needs.

## What the research says

- Application of 15% azelaic acid gel significantly reduced post-inflammatory erythema and hyperpigmentation, decreased hemoglobin and melanin content, improved quality of life, and contributed to acne improvement in patients with mild to moderate acne compared to placebo. ([Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/))
- 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/))
- 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/))
- Topical tretinoin improves clinical appearance of photoaging in terms of wrinkling, mottled hyperpigmentation, sallowness, and lentigines and is safe and well tolerated. ([International Journal of Women's Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35620028/))
- 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/))
- Topical tretinoin significantly improved photoaging and caused histologic changes in the forearms and faces of treated patients compared to vehicle cream, with side effects limited to skin irritation. ([JAMA, 1988](https://pubmed.ncbi.nlm.nih.gov/3336176/))
- 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/))
- Topical application of a dermocosmetic containing Myrtus communis extract and azelaic acid reduced acne relapses and helped maintain remission compared to a light moisturizing cream in adult females in the acne maintenance phase over 16 weeks.

- 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 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. ([Journal of the American Academy of Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37656094/))
- Clindamycin-BPO 2.5% aqueous gel applied once daily provided statistically significant greater efficacy than individual active ingredients and vehicle in reducing inflammatory and noninflammatory lesions and acne severity in 2813 patients with moderate to severe acne vulgaris.

## Questions and answers

### Why is Curology Formula a weak match for sensitive skin?

Curology Curology Formula is a weak match for sensitive skin because its tretinoin and clindamycin may cause irritation and worsen sensitivity, even though azelaic acid helps with redness. A treatment of this type needs soothing ingredients, potent antioxidants, hydrating components, and skin-repairing ingredients to keep sensitive skin calm and comfortable.
Sources: [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/)

### Which ingredients make this treatment a poor fit for sensitive skin?

Tretinoin and clindamycin make this treatment a weak match because they may worsen sensitivity and cause irritation for your skin. Treatments for sensitive skin need soothing and hydrating ingredients, like niacinamide, snail secretion filtrate, and antioxidants, alongside no risk of irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32210603/), [Archives of Dermatological Research, 2022](https://pubmed.ncbi.nlm.nih.gov/34146120/)

### What does Tretinoin do for sensitive skin?

Tretinoin can be used on sensitive skin when integrated into a comprehensive skincare routine with gentle cleansers and moisturizers, though it requires careful introduction to manage irritation. Lower retinoid concentrations and specific formulations are associated with improved facial tolerability in healthy volunteers.
Sources: [International Journal of Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/39551973/), [Journal of Drugs in Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/15624747/)

### What does Azelaic Acid do for sensitive skin?

Azelaic acid helps calm sensitive, red, or easily irritated skin by soothing inflammation and reducing redness. It is generally well-tolerated and is unlikely to cause severe reactions, making it a gentle option for skin that flares up easily.
Sources: [Experimental Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20545756/), [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/21637903/)

### Where does this treatment go in a skincare routine for sensitive skin?

This treatment goes in the evening routine after cleansing and toning and before moisturizing, though it is a weak match that may worsen your sensitive skin. A product of this type for sensitive skin needs extra hydrating ingredients and soothing agents to calm redness and prevent irritation.

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

You can use this treatment with niacinamide by applying niacinamide first and letting it absorb before putting on this formula. This combination helps calm redness while managing blemishes, though you should watch closely for any dryness or stinging since both ingredients can be strong on easily irritated skin.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38102855/), [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/)

### How often should I use this treatment?

This treatment is unlikely to be a good fit for your sensitive skin because its active ingredients may cause irritation and redness. A product of this type needs soothing and hydrating ingredients to keep sensitive skin calm and soft.

### Can this treatment clog pores, cause breakouts or purging for sensitive skin?

This treatment is unlikely to clog pores, but the tretinoin and clindamycin in it may cause irritation and breakouts on sensitive skin. A product for this skin needs soothing, hydrating ingredients to keep the skin calm and comfortable.
