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 toners fit it better.

## Why this fit

- Offers moderate exfoliation suitable for normal skin, as gluconolactone and lactic acid gently promote cell turnover without causing irritation.
- While beneficial for general skin health, the formula does not directly target your specific concerns of redness and irritation.
- The product is safe for your sensitive skin, with no harsh ingredients or prohibited substances that could cause adverse reactions.

## What the research says

- Glycolic acid, salicylic acid, gluconolactone, and licochalcone A combined with 0.1% adapalene showed no hindrance compared to adapalene monotherapy and provided benefits in reducing complications in 25 subjects with mild-to-moderate acne vulgaris. ([Clinical, Cosmetic and Investigational Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30858720/))
- Gluconolactone and tartaric acid significantly lower transepidermal water loss and erythema after sodium lauryl sulphate challenge compared to vehicle, untreated control, and glycolic acid in healthy subjects. ([The British Journal of Dermatology, 1997](https://pubmed.ncbi.nlm.nih.gov/9470910/))
- Gluconolactone 14% solution significantly improved mild to moderate acne by reducing inflamed and non-inflamed lesions similarly to 5% benzoyl peroxide, but with fewer side-effects in 150 patients. ([The Australasian Journal of Dermatology, 1992](https://pubmed.ncbi.nlm.nih.gov/1303072/))
- 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/))
- Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients. ([CMAJ, 2010](https://pubmed.ncbi.nlm.nih.gov/20837684/))

- Topical 12% ammonium lactate produced a significant sparing of epidermal and dermal atrophy induced by clobetasol propionate in human volunteers, without influencing the corticosteroid's bioavailability or antiinflammatory properties. ([Journal of the American Academy of Dermatology, 1992](https://pubmed.ncbi.nlm.nih.gov/1597538/))

## What reviewers say

Users consistently describe this toner as a "facial in a bottle" specifically suited for mature, dry, or "devitalized" skin due to its vitamin-enriched formula. While gentler than the original P50, it is highly praised for effectively resurfacing texture and creating a "glass skin" glow without stripping moisture, though the application process requires tolerance for its potent scent and sensation.

- Liked: Radiant glow (mostly mentioned)
- Disliked: Unpleasant scent (mostly mentioned)
- Liked: Smoother texture (often mentioned)
- Disliked: High price point (often mentioned)
- Liked: Non-drying/balancing (sometimes noted)
- Liked: Pore refinement (sometimes noted)
- Disliked: Initial irritation (sometimes noted)
- Disliked: Hard to purchase (rarely noted)

## How to apply

- Use your exfoliating toner as part of a PM routine once a week to start. Carefully increase frequency only if your skin tolerates it well.
- Apply this exfoliating toner after cleansing and before your moisturizer. It fits right into your usual step for toners.
- Gently press 2-3 drops of the exfoliating toner into your skin. Avoid rubbing to keep redness down.
- Apply the exfoliating toner on completely dry skin to help improve your skin's tolerance. This helps protect your sensitive face.
- Do a patch test before your first use and avoid the delicate eye area . Skip strong acids or retinoids on the same night.

## Questions and answers

### How well does Lotion P50V work for sensitive skin?

Biologique Recherche Lotion P50V is an average fit for sensitive skin because it gently exfoliates without causing harsh reactions, though it does not actively calm redness. An exfoliating toner for sensitive skin needs soothing ingredients and gentle acids that smooth texture while actively reducing redness and irritation.

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

Gluconolactone and lactic acid help make this toner a good fit by gently promoting cell turnover without causing irritation. Because this is only an average fit for sensitive skin that experiences redness, this type of product needs soothing ingredients and gentle exfoliants that improve texture and radiance without harsh acids.

### What does Gluconolactone do for sensitive skin?

Gluconolactone helps smooth and care for sensitive skin while causing fewer side-effects than traditional blemish treatments. It provides gentle exfoliating and protective benefits without irritating easily upset skin.

### 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 toner go in a skincare routine for sensitive skin?

This exfoliating toner fits into a routine for sensitive skin by starting out just once a week. A sensitive skin routine needs gentle exfoliants and soothing, calming ingredients to keep skin smooth without causing redness or irritation.

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

This toner can be used alongside a retinol, but it is best to apply them on alternate nights or separate times of day to keep sensitive skin calm and comfortable. Using multiple strong active ingredients at once may increase the likelihood of dryness or irritation.

### How often should I use this toner?

Start using this toner just once a week since it is an exfoliating product for sensitive skin, and you can slowly use it more often only if your skin handles it well without irritation.

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

This toner is unlikely to clog pores, but it may cause mild initial irritation on sensitive skin due to its exfoliating ingredients. Because it contains lactic and salicylic acid to promote cell turnover, some minor purging can happen when you first start using it.

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

Yes, it has no fragrance and no drying alcohol.
