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

Works for mature skin; other serums fit it better.

## Why this fit

- Offers moderate brightening for your normal skin due to Alpha-Arbutin and Niacinamide, which help regulate melanogenesis and provide antioxidant activity.
- While it offers general hydration and soothing benefits, it lacks specialized ingredients to effectively target your wrinkles and fine lines.
- The product is safe for your normal skin, with no risks of irritation from 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 mature skin better

- Topical application of retinol and retinoic acid both increased epidermal thickness and upregulated collagen genes and proteins in human skin, with retinol producing similar histological and molecular changes to retinoic acid alongside a significant reduction in facial wrinkles after 12 weeks. ([Journal of Cosmetic Dermatology, 2016](https://pubmed.ncbi.nlm.nih.gov/26578346/))
- A topical serum containing vitamin C, vitamin E, and raspberry leaf cell culture extract improved skin color, elasticity, radiance, smoothness, scaliness, and wrinkles compared to the untreated contralateral side in fifty female volunteers. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/))

## 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.

## Questions and answers

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

This treatment works moderately well for mature skin because it brightens and calms, but a product of this type needs specialized anti-aging ingredients and potent antioxidants to effectively smooth fine lines and wrinkles.
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 mature skin?

Alpha-Arbutin and Niacinamide make this a decent fit by offering moderate brightening and antioxidant support. However, mature skin needs treatments with high-quality anti-aging ingredients, potent antioxidants, hydrating components, and skin-repairing elements like nourishing oils and peptides to effectively target wrinkles and fine lines.

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

Tranexamic acid helps reduce brown spots and uneven tone while improving overall skin brightness. Studies show that using it regularly can fade stubborn pigmentation safely and with very little irritation.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38549196/), [Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/33022197/)

### What does Niacinamide do for mature skin?

Niacinamide helps mature skin by smoothing out fine lines and wrinkles, reducing dark spots, and improving overall skin elasticity. It is also very well tolerated and supports a strong skin barrier to keep skin looking healthy.
Sources: [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/), [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/)

### Where does this treatment go in a skincare routine for mature skin?

This treatment goes in your evening routine, applied after cleansing and before your moisturizer. Mature skin also needs specialized ingredients like firming peptides and retinoids to effectively target wrinkles and fine lines.

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

You can use this treatment with retinol by applying the retinol first and following with this product, or by using retinol on some nights and this treatment on others. It is safe for your skin, though a product for mature skin also needs specialized ingredients to effectively target wrinkles and fine lines.

### How often should I use this treatment?

This treatment is used in the evening, applying it during your night routine. It is safe for your skin, though mature skin also needs specialized ingredients that smooth fine lines and wrinkles.

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

This treatment is unlikely to cause breakouts or clog pores on mature skin, as it has a very low risk of irritation and reviewers rarely report breakouts. To better care for mature skin, this type of product needs added ingredients that target fine lines and wrinkles.
