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

Brand: [The INKEY List](https://lovi.care/skincare/es/brands/the-inkey-list)
Category: [Serums and treatments](https://lovi.care/skincare/es/best/serums)

This fit is calculated for the concerns frequently associated with dry sensitive skin: flakiness, tightness, redness, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

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

## Why this fit

- Offers moderate exfoliation for dry or flaky skin due to Mandelic Acid, but the inclusion of Retinol may pose risks of further drying and irritation for your sensitive, dry skin.
- The formula is moderately unsuitable for dry skin as it lacks sufficient emollient and occlusive ingredients to counteract the potential dryness and irritation from Mandelic Acid.

## What the research says

- 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/))
- 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/))
- 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/))
- 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 dry 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/))
- In 50 participants with sensitive skin, a Ceramide NP C15-containing emollient improved skin barrier function with a significant reduction in transepidermal water loss and induced modest changes in skin microbiota compared to the vehicle. ([Skin Pharmacology and Physiology, 2026](https://pubmed.ncbi.nlm.nih.gov/41758783/))
- 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/))

## How to apply

- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

## Questions and answers

### Why is INKEY List Mandelic Acid Treatment a weak match for dry sensitive skin?

This treatment is a weak match because mandelic acid and retinol may cause extra dryness, scaling, and irritation on dry sensitive skin. It also lacks enough rich, softening ingredients to protect and hydrate this skin type. A product for dry sensitive skin needs soothing moisturizers and gentle hydrators that smooth and comfort without irritation.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Mandelic acid and retinol make this treatment a weak match because they may cause extra dryness and irritation on sensitive, dry skin. A product of this type needs rich nourishing and moisturizing ingredients that lock in moisture and support the skin barrier without any risk of irritation.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Mandelic acid is very well tolerated by sensitive skin, and it helps smooth out rough patches and improves firmness without causing too much irritation.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/35796684/)

### What does Glycerin do for dry sensitive skin?

Glycerin helps dry sensitive skin by drawing moisture into the skin and keeping it there, making the skin soft and smooth. It is very gentle and unlikely to cause irritation while improving how well the skin holds onto water. This type of skin needs ingredients that boost hydration and repair the barrier without causing stinging.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/)

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

This treatment goes in the evening routine once a week, as dry sensitive skin needs a careful approach with strong exfoliating acids and retinol. A product of this type for dry sensitive skin needs plenty of rich, softening ingredients and moisture-locking barriers to prevent dryness and irritation.

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

You can use this treatment with niacinamide, but apply niacinamide first and let it absorb before applying this product to help keep your dry skin calm. Because this product contains exfoliating acid and retinol, your dry and sensitive skin needs extra rich, soothing creams and barrier-protecting ingredients to prevent dryness and stinging.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38102855/), [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### How often should I use this exfoliant?

This product is a weak fit for your dry sensitive skin because the exfoliating acid and retinol may cause dryness and irritation. A product of this type needs plenty of rich, softening ingredients and skin-protecting oils to keep dry sensitive skin smooth, calm, and comfortable.

### Can it clog pores, cause breakouts or purging for dry sensitive skin?

It is unlikely to clog pores, but the retinol inside may cause some flaking and irritation on your dry sensitive skin. A product of this type needs rich softening and sealing ingredients to keep dry skin smooth and comfortable.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Is this exfoliant 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.
