This fit is calculated for the concerns frequently associated with dark spots: hyperpigmentation, sun spots, and uneven skin tone. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for skin with dark spots; other serums fit it better.

## Why this fit

- Offers moderate brightening and evening of skin tone for your normal skin due to the presence of tetrahexyldecyl ascorbate and glutathione, which support your main goal of pigmentation. Glycerin and tocopherol provide general skincare benefits like hydration and antioxidant protection, which are supportive but not directly targeted at your primary concern.
- The formula is highly suitable for normal skin, with ingredients like tetrahexyldecyl ascorbate and ascorbic acid stimulating collagen and providing antioxidant activity.
- The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.

This treatment works moderately well for skin with dark spots, offering some brightening and evening of skin tone while keeping your normal skin calm and hydrated.

### Which ingredients make this serum a good fit for skin with dark spots?

This serum fits skin with dark spots thanks to tetrahexyldecyl ascorbate and glutathione, which help brighten the skin and even out its tone. To work best for this skin type, a product of this type needs a blend of effective antioxidants and soothing ingredients that fade dark spots without causing irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/25378941/)

### What does Vitamin C do for skin with dark spots?

Vitamin C helps fade dark spots and brightens uneven skin. It works by slowing down pigment production and boosting overall skin clarity.
Sources: [Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029672/)

### What does Glutathione do for skin with dark spots?

Glutathione helps brighten skin with dark spots and evens out skin color. Topical and oral use may reduce dark patches and protect against environmental stress with a good safety profile.
Sources: [Journal of Cosmetic Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30895708/), [International Journal of Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/39444151/)

### Where does this serum go in a skincare routine for skin with dark spots?

This treatment goes in the evening routine after cleansing and before moisturizing, which keeps application simple and safe around sun exposure. Skincare for dark spots generally needs targeted brightening ingredients like vitamin C and antioxidants to help fade spots and even out tone.
Sources: [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36607762/)

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

You can use this serum with retinol by applying the retinol first, letting it absorb, and then following with this treatment, or by using retinol on alternate nights to keep your skin calm. This product works for dark spots, but to truly fade them effectively, skin with dark spots needs dedicated brightening ingredients like pure vitamin C and powerful antioxidants.

### How often should I use this serum?

This treatment serum works well for evening out skin tone, though skin with dark spots often needs products with more targeted brighteners and antioxidants to see the best results. You can use it in the evening, and a product for this skin needs strong brightening ingredients like kojic acid, alpha arbutin, or niacinamide alongside antioxidants to effectively fade dark spots.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/25378941/)

### Can this serum clog pores, cause breakouts or purging for skin with dark spots?

This serum is unlikely to cause breakouts for skin with dark spots, as reviewers rarely report clogged pores and the formula has a very safe profile. Skin with dark spots typically benefits most from a treatment that combines high-strength brightening ingredients like hydroquinone, kojic acid, or tranexamic acid with reliable gentle exfoliants.

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

Yes, it has no fragrance and no drying alcohol. Cetyl alcohol is a fatty alcohol, which soften the skin.
