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

Brand: [The INKEY List](https://lovi.care/skincare/it/brands/the-inkey-list)
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 exfoliation for your normal skin due to mandelic acid and retinol, which help decongest pores and support cell turnover, but lacks ingredients to specifically address your redness and irritation.
- While the product provides general hydration and soothing benefits, these are not specialized enough to significantly improve your primary concerns.
- The formula is generally safe for your sensitive skin, though the presence of mandelic acid and retinol carries a slight risk of irritation.

## What the research says

- Topical 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle. ([International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/))
- Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging. ([The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/))
- Treatment with 45% mandelic acid peel showed nearly equal overall efficacy as 30% salicylic acid peel in patients with mild-to-moderate facial acne vulgaris, but with fewer adverse effects. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31553119/))
- Chemical peels using 35% glycolic acid, 20% salicylic-10% mandelic acid, and phytic acid reduce acne scores by 70.55%, 74.14%, and 69.7% respectively, and significantly decline the postacne hyperpigmentation index in Asian patients with mild to moderate acne. ([Journal of Cutaneous and Aesthetic Surgery, 2019](https://pubmed.ncbi.nlm.nih.gov/31619887/))
- Commonly used chemical peels showed no significant differences in effectiveness for acne vulgaris in most comparisons, though combined salicylic and mandelic acid peeling was superior to glycolic acid and glycolic acid was superior to placebo, based on twelve randomized controlled trials. ([BMJ Open, 2018](https://pubmed.ncbi.nlm.nih.gov/29705755/))
- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Silicone particles encapsulating retinol increased its half-life by 9-fold and yielded 12-23% lower skin irritation in human subjects compared to Microsponge particles while maintaining biological activity. ([Journal of Controlled Release, 2018](https://pubmed.ncbi.nlm.nih.gov/29604311/))
- Topical stabilized retinol treatment induced HAS gene expression and increased hyaluronic acid production in human skin in vitro, ex vivo, and in vivo compared to vehicle. ([Archives of Dermatological Research, 2017](https://pubmed.ncbi.nlm.nih.gov/28247017/))
- Topical application of all-trans-retinol induced epidermal thickening and increased retinoid binding protein expression similar to all-trans-retinoic acid in normal human skin, but without causing significant erythema or measurable retinoic acid levels. ([The Journal of Investigative Dermatology, 1995](https://pubmed.ncbi.nlm.nih.gov/7561157/))
- Treatment with 14% ferulic acid and 12% l-ascorbic acid significantly reduced pigmentation and erythema while improving hydration and elasticity in 20 women with photoaged skin, with neither acid proving definitively more effective overall though ascorbic acid showed slightly greater skin lightening. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/34877760/))
- Combining fractional microneedle radiofrequency with a topical antioxidant serum significantly reduced wrinkle severity by 29.9% versus 18.0%, increased elasticity by 12.9% versus 2.3%, and improved aesthetic outcomes in 31 participants compared to radiofrequency and placebo. ([The Journal of Dermatological Treatment, 2025](https://pubmed.ncbi.nlm.nih.gov/40464749/))
- Pretreatment with a topical antioxidant mixture of vitamin C, ferulic acid, and phloretin attenuated ultraviolet-induced sunburn cell formation, thymine dimer formation, matrix metalloproteinase-9 expression, p53 protein expression, and the suppression of CD1a-expressing Langerhans cells in human skin compared to vehicle control. ([Journal of Cosmetic Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/19146606/))

## Why other serums fit sensitive skin better

- Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging. ([The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/))
- Topical application of TAT-SOD significantly suppresses UVB-induced erythema formation, blood flow rise, and apoptotic sunburn cell formation in human volunteers compared to a vehicle control. ([European Journal of Pharmaceutics and Biopharmaceutics, 2016](https://pubmed.ncbi.nlm.nih.gov/27460952/))

## Questions and answers

### How well does The INKEY List Mandelic Acid work for sensitive skin?

The INKEY List Mandelic Acid Treatment is an average fit for sensitive skin because, while it offers moderate exfoliation and general hydration, it lacks targeted ingredients to address redness and irritation and carries a slight risk of irritation. A treatment of this type needs soothing ingredients like niacinamide and snail secretion filtrate to properly care for sensitive skin.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Glycerin helps make this exfoliant a fit by providing gentle hydration, while mandelic acid and retinol offer moderate surface renewal. However, because this product only works as an average fit for sensitive skin, treatments of this type need soothing ingredients like niacinamide or snail secretion filtrate to properly target redness and irritation without triggering discomfort.
Sources: [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/), [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Mandelic acid is generally well tolerated by sensitive skin, helping to smooth roughness and improve firmness while keeping side effects low. It may also help clear acne and reduce dark spots effectively without being too harsh.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/35796684/), [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31553119/)

### What does Glycerin do for sensitive skin?

Glycerin helps keep sensitive skin soft and deeply hydrated while supporting the skin barrier. It is unlikely to cause irritation and may protect against dryness and roughness.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [Acta Dermato-venereologica, 1999](https://pubmed.ncbi.nlm.nih.gov/10598752/)

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

This treatment goes in your evening routine, starting at once a week to lower the chance of irritation. Sensitive skin needs gentle soothing and calming ingredients to manage redness while it gets used to active ingredients.

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

You can use this treatment with niacinamide, applying the niacinamide first and letting it soak in before putting on this treatment to help keep your skin calm. Sensitive skin needs a product of this type to include extra calming and redness-reducing ingredients alongside gentle hydrators.

### How often should I use it?

Start by using this treatment once a week in your evening routine, and carefully use it more often only if your skin tolerates it well without irritation. The formula is generally safe for your sensitive skin, but the presence of mandelic acid and retinol carries a slight risk of stinging and dryness.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/), [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

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

This treatment helps clear pores and support skin renewal, but the mandelic acid and retinol in it carry a slight risk of causing irritation or breakouts on sensitive skin. To truly fit sensitive skin, a product of this type needs calming ingredients and extra soothing support that reduce redness.
Sources: [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/), [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Is it fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (benzyl alcohol). Cetearyl alcohol is a fatty alcohol, which soften the skin.
