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

Brand: [COSRX](https://lovi.care/skincare/de/brands/cosrx)
Category: [Serums and treatments](https://lovi.care/skincare/de/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 brightening for your normal skin, as Alpha-Arbutin and Niacinamide work to even skin tone and regulate melanogenesis.
- While beneficial for general skincare, the formula lacks specialized ingredients to target your redness and irritation.
- The product is safe for your normal skin with sensitivity, as it contains no harsh or prohibited ingredients.

## Key ingredients

Tranexamic Acid, Niacinamide, N-Acetyl Glucosamine Nag

## What the research says

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Encapsulation of alpha arbutin in an optimized ethosomal gel significantly improved skin melanin reduction, moisture content, and elasticity in human volunteers compared to conventional formulations. ([Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/))
- 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/))
- N-acetylglucosamine dose dependently increased hyaluronan production in cultured keratinocytes, and its combination with retinoic acid or retinol exerted a synergistic effect. ([Skin Pharmacology and Physiology, 2004](https://pubmed.ncbi.nlm.nih.gov/14976384/))
- Exogenous N-acetylglucosamine promotes hyaluronan production while having no effect on the expression of hyaluronan-synthesizing enzymes 1, 2, and 3 mRNA in cultured human dermal fibroblasts. ([Archives of Dermatological Research, 2009](https://pubmed.ncbi.nlm.nih.gov/19247681/))
- Global gene expression profiling and in vitro biomarker approaches in human skin equivalent cultures successfully detected specific skin barrier, matrix, and hydration responses to topical compounds including niacinamide, hexamidine, Pal-KT, Pal-KTTKS, and N-acetylglucosamine. ([Journal of Drugs in Dermatology, 2009](https://pubmed.ncbi.nlm.nih.gov/19623777/))

## Why other serums fit sensitive skin better

- 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/))

## What reviewers say

This serum is highly praised for its lightweight, watery texture that absorbs quickly and layers well, making it suitable for sensitive and acne-prone skin. While many users report positive results in fading dark spots and brightening skin tone, some note that significant improvements in hyperpigmentation take several weeks of consistent use.

## How to apply

- Use your serum in the PM routine, starting 3 times a week before building up to daily use if your skin is happy.
- Apply the serum after cleansing and toning, but before putting on your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin and wait a minute ⏱ for it to soak in.
- Since your skin is sensitive and easily irritated, apply the serum on completely dry skin to help keep it calm.
- Always do a patch test before your first use and avoid getting the serum too close to your eyes .

## Questions and answers

### How well does COSRX The Alpha-Arbutin 2 Discoloration Care work for sensitive skin?

This product is an average fit for your sensitive skin because, while it is safe and helps even out your skin tone, it lacks specialized ingredients to target your redness and irritation. Treatments that fit this skin better need soothing ingredients that reduce redness and irritation while keeping the skin calm.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Heliyon, 2023](https://pubmed.ncbi.nlm.nih.gov/37681127/)

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

Alpha-Arbutin and Niacinamide help even skin tone on sensitive skin by regulating pigment production, while Tranexamic Acid and N-Acetyl Glucosamine further support this brightening effect. However, because this treatment lacks specialized ingredients to soothe redness and irritation, a product for this skin type needs calming plant extracts, soothing antioxidants, and deep hydrators to provide a better fit.

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

Tranexamic acid helps calm sensitive skin by strengthening the skin barrier and reducing redness and flushing. It is unlikely to cause severe reactions, making it a well-tolerated choice for reactive or easily irritated skin.
Sources: [International Journal of Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/23967870/), [Clinical, Cosmetic and Investigational Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38895607/)

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

This treatment goes in the evening routine after cleansing and a soothing toner, followed by a moisturizer. A product of this type needs calming ingredients to help soothe redness and irritation for this skin.

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

You can use this treatment alongside retinol by applying the treatment first and following with your retinol on separate nights or spaced carefully to avoid irritation. A product for sensitive skin needs calming ingredients and extra soothing agents to help prevent redness and keep the skin calm.

### How often should I use this treatment?

Apply this treatment in the evening, starting once a week to see how your skin reacts. This product needs calming and soothing ingredients like centella or green tea to better target redness and irritation on sensitive skin.

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

This treatment is unlikely to clog pores or cause breakouts for sensitive skin, as reviewers report very low rates of breakouts and irritation. A product of this type for sensitive skin needs calming ingredients like centella asiatica or soothing plant extracts to help keep redness and irritation down.
