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

Brand: [La Roche-Posay](https://lovi.care/skincare/it/brands/la-roche-posay)
Category: [Serums and treatments](https://lovi.care/skincare/it/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.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate benefits for your normal skin, as retinol and niacinamide work to renew texture and minimize fine lines, while glycerin and sodium hyaluronate provide essential hydration.
- While supportive for redness and irritation, the formula lacks specialized ingredients to directly target these concerns, offering general skincare advantages instead.
- The product is safe for your sensitive skin, with no harsh ingredients and the inclusion of soothing niacinamide.

## Questions and answers

### How well does La Roche-Posay Retinol B3 work for sensitive skin?

La Roche-Posay Retinol B3 Serum is an average fit for sensitive skin, offering moderate texture renewal and hydration while lacking specialized ingredients for redness and irritation. A treatment for this skin needs ingredients that directly target redness and irritation with no risk of irritation, like niacinamide and snail secretion filtrate.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this serum a good fit for sensitive skin?

Niacinamide and soothing thermal spring water help calm sensitive skin, while glycerin and sodium hyaluronate provide essential hydration without harsh effects. For sensitive skin needing a better fit, treatments require specialized ingredients that directly target redness and irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Journal of the European Academy of Dermatology and Venereology, 2020](https://pubmed.ncbi.nlm.nih.gov/32870553/)

### What does Retinol do for sensitive skin?

Retinol is generally too harsh for sensitive skin and may cause stinging, scaling, and irritation. A product for this skin needs gentle ingredients that smooth and calm without causing redness.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/), [Toxicology Letters, 2003](https://pubmed.ncbi.nlm.nih.gov/14615068/)

### What does Niacinamide do for sensitive skin?

Niacinamide helps calm sensitive skin by strengthening the skin barrier and reducing redness and irritation. It is very well tolerated and may improve overall comfort and resilience with regular use.
Sources: [Cutis, 2005](https://pubmed.ncbi.nlm.nih.gov/16209160/), [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/)

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

This treatment goes in the evening routine after cleansing and toning, and before moisturizing. It is safe for sensitive skin because it avoids harsh ingredients and includes soothing niacinamide, though this skin type needs extra calming and barrier-supporting ingredients to best target redness and irritation.

### Can I use this serum with vitamin C, and in what order?

You can use this serum with vitamin C by applying your vitamin C in the morning and this serum at night to avoid overwhelming your skin. Using strong active ingredients separately helps keep your skin calm and comfortable.

### How often should I use this serum?

Use this treatment serum in your evening routine, starting slowly to see how your skin adjusts. While it is generally safe, this skin type needs extra soothing ingredients and targeted calming agents to manage redness and irritation effectively.

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

This serum is unlikely to cause breakouts, but it may cause mild purging as the retinol helps renew your skin texture and smooth fine lines. Because this is an average fit for sensitive skin, a product of this type needs extra soothing ingredients and gentle hydrators to keep your skin calm and comfortable.

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

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